Try reading the documentation on the DateTime structure, here[^].
Dim databaseUtcTime = dateTimeFromDatabase
databaseUtcTime = databaseUtcTime.SpecifyKind(DateTimeKind.Utc)
Debug.WriteLine(String.Format("UtcTime: {0}", databaseUtcTime.ToString()))
Debug.WriteLine(String.Format("LocalTime: {0}", databaseUtcTime.ToLocalTime().ToString()))

Alright, this is not exactly a programming question, but I also doubt that it would fit into the Lounge.
Situation: I am currently implementing the Syslog Protocol in .Net, starting with the Base classes (Message, Header, Struct. Data). The Header contains a timestamp which's formatting is exactly defined.
A timestamp may look as follows:
2014-2-4T14:22:56.235Z+1
2014-2-4T14:22:56.235Z-1.5
2014-2-4T14:22:56.235123Z+1
What I have done so far is that I consider System.DateTime being unuseable as timestamp, even with a wrapper around it it would be highly difficult since setting a single field (e.g. Day, Year, Month and so on) is only possible by parsing an entire time string, or adding a Time span.
Now to avoid these circumstances, I have implemented the following class SyslogTimestamp:
using System;

Assert.AreEqual(true, (timestamp4 > timestamp1));
Assert.AreEqual(false, (timestamp1 < timestamp2));
Assert.AreEqual(true, (timestamp1 >= timestamp2));
Assert.AreEqual(false, (timestamp1 <= timestamp2));
Assert.AreEqual(true, (timestamp1 == timestamp3));
Assert.AreEqual(false, (timestamp1 != timestamp3));
Assert.AreEqual(false, (timestamp1 == timestamp4));
Assert.AreEqual(false, (timestamp1 == timestamp2));
}
[TestMethod]
public void SyslogTimestampStringConversionIntegrity()
{
DateTime now = DateTime.Now;
SyslogTimestamp timestamp = new SyslogTimestamp();
SyslogTimestamp timestamp2 = new SyslogTimestamp();
timestamp.FromDateTime(now);
timestamp.UtcOffset = 1;
Assert.AreEqual(true, timestamp2.FromString(timestamp.ToFormattedString()));
Assert.AreEqual(true, (timestamp2 == timestamp));
}
}
}
Now my question is: Can I achieve the same with System.DateTime?
I seriously doubt that, since System.DateTime's ParseExact method tends to have problems dealing with a variable amount of microseconds, and does not provide any field to store the UTC Offset.
Edit: I provided the new class implementation, since I have added various improvements.

personally I would never re-write it. I once tried and though it was more than a reasonable effort, the amount of rules and things to think of becomes very large and does not outwheigh the disadvantages of being stuck with the standard DateTime.
([SMALL RANT]And I'm now working with Java's GregorianCalendar, how I wish I had a DateTime object  [/SMALL RANT])
Marco Bertschi wrote: since System.DateTime's ParseExact method tends to have problems dealing with a variable amount of microseconds, and does not provide any field to store the UTC Offset.
Variable microseconds can be handled with a few lines of business logic I think and for the UTC Offset you could create a new DateTime Object that inherits from the DateTime class? (just a quick thought)
good luck.

The big deal is that the Syslog Timestamp has special characters in it, in order to make it better parseable. ParseExact can't handle them properly, somehow.
V. wrote: for the UTC Offset you could create a new DateTime Object that inherits from the DateTime class? (just a quick thought)
And then I'd end up with what I already have, since the UTC Offset must be recognized when comparing two types of the new datetime class.
In the end I'd say that it is a reasonable amount of work, especially since Date/Time stuff isn't going to change too soon, and if it has proven itself worth the work it will last longer than both of us will ever live.

DateTime is a sealed class, so you can't inherit from it.

Crap. I saw "Timestamp" read it "Timespan".

Based on the observation that all of your Properties, except milliseconds, are 'get only, I would say "yes," if you were willing to accept the limitations of inheriting from a data-structure like a Tuple<T1,T2,T3> ... given the fact that Tuple instances are immutable.
I don't claim to have thought through your use scenario here in any great depth, or to fully understand your goals here, but here's a quick sketch:
using System;
namespace Feb4_2014_InheritFromTupleT1T2T3
{
public class DateTimeEx: Tuple<DateTime, long, Int32>
{
private const string msPrefix = ":Z";
private const string tzPlus = "+";
private string tzPre;
public DateTime dateTime { set; get; }
public long milliSeconds { set; get; }
public Int32 utcOffset { set; get; }
public DateTimeEx(DateTime datetime, long millisec, Int32 utcoff) : base(datetime, millisec, utcoff)
{
dateTime = datetime;
milliSeconds = millisec;
utcOffset = utcoff;
}
public override string ToString()
{
tzPre = (milliSeconds < 0) ? "" : tzPlus;
return string.Format("{0}-{1}-{2}T{3}:{4}:{5}.{6}Z{7}{8}", Item1.Year, Item1.Month, Item1.Day, Item1.Hour, Item1.Minute, Item1.Second, milliSeconds, tzPre, utcOffset);
}
}
}Here's the results of a simple test:
DateTime rightNow = DateTime.Now;
DateTimeEx dEx1 = new DateTimeEx(rightNow, 0, 7);
DateTimeEx dEx2 = new DateTimeEx(rightNow, 0, 7);
DateTimeEx dEx3 = new DateTimeEx(rightNow, 230, 4);
Console.WriteLine(dEx1);
Console.WriteLine(dEx3);
Console.WriteLine(dEx1.Equals(dEx2));
Console.WriteLine(dEx1.Equals(dEx3)); I would hope what you would get from this is being able to use Parse, and ParseExact on the DateTime component, and, hopefully, save you from writing some of the overloads. But, whether you could use in the context of whatever your doing with SysLog: I ain't got a clue.
Hope this is helpful.

The read-only behavior will change soon, I only have to implement the value validation first.
BillWoodruff wrote: would hope what you would get from this is being able to use Parse, and ParseExact on the DateTime component,
I will almost certainly not be able to, since the UTC-Offset at the end (after the "Z") can't be handled by these functions. An overload may make sense, but will eventually end up in a big mess with the comparison operators.
I did some thinking myself in the meantime, and I consider an overloading of DateTime bein highly unusable, especially since DateTime has to present a Date/Time pair which may change, and a Timestamp has to represent a single Date/Time/UTC-Offset pair which is not going to change after its initialization (Apart from the problems of inheriting a struct which you already have mentioned).

You have effectively two 'layers' which needs a 'translation' layer in between.
That doesn't require a new timestamp class. What it requires is that you create functionality that parses (and formats if needed) and that goes in your translation layer. On the C# (application side) the input/output is a DateTime. On the syslog interface side it is a string.

Yes, that's why the new class has a "FromDateTime(DateTime dateTime)"-Method.
jschell wrote: On the syslog interface side it is a string.
I am the one who provides the classes to serialize/deserialze the Syslog message, therefore a class might be useful, especially afterwards when showing the messages in the Logviewer (Ordering them by a timestamp type has almost certainly advantages over ordering them by a string which represents a timestamp).
I might be wrong in some point here (or I may not). I'll just go ahead and see what I'll learn. It's a side project which I do in my free time, so I am allowed to spend time making errors (and learning from them).

Marco,
In your lounge post[^] you say that you imposing RFC5424[^] as the criteria. Based on the following format that I found online, you will not be able to properly store a RFC5424 timestamp in a DateTime structure due to the possibility of the TIME-SECFRAC being allowed to have up six digits. The DateTime structure can only accommodate milliseconds (3 digits).
Quote: TIMESTAMP = NILVALUE / FULL-DATE "T" FULL-TIME
FULL-DATE = DATE-FULLYEAR "-" DATE-MONTH "-" DATE-MDAY
DATE-FULLYEAR = 4DIGIT
DATE-MONTH = 2DIGIT ; 01-12
DATE-MDAY = 2DIGIT ; 01-28, 01-29, 01-30, 01-31 based on
; month/year
FULL-TIME = PARTIAL-TIME TIME-OFFSET
PARTIAL-TIME = TIME-HOUR ":" TIME-MINUTE ":" TIME-SECOND
[TIME-SECFRAC]
TIME-HOUR = 2DIGIT ; 00-23
TIME-MINUTE = 2DIGIT ; 00-59
TIME-SECOND = 2DIGIT ; 00-59
TIME-SECFRAC = "." 1*6DIGIT
TIME-OFFSET = "Z" / TIME-NUMOFFSET
TIME-NUMOFFSET = ("+" / "-") TIME-HOUR ":" TIME-MINUTE
You also have shown TimeStamp examples[^] that you say are valid. However these have decimal TIME-NUMOFFSET values instead of "Hours:Minutes"; again this conflicts with the specification. Is it your intent to allow these deviations?
Just courious, is there a reason that you have implemented your own GetDayMaxDaysOfMonth and Is LeapYear versus using those from the DateTimeStructure (DateTime.DaysInMonth[^], DateTime.IsLeapYear[^])?

Pssst - I simply forgot about those
On the other hand side I didn't really bothered to check for something existing, since I had to learn the leap year rules anyways.

Marco,
My statement "The DateTime structure can only accommodate milliseconds (3 digits)" was incorrect.  Sorry about that.
You can access higher resolution through the usage of the Ticks property that has a 100 nanosecond resolution[^].
You could use DateTime.TryParseExact with this format string: "yyyy-MM-dd\THH:mm:ss"
If that succeeds then, then you would need to extract the fractional second component (if it exists) as microseconds (upto 6 digits) and convert the microseconds to Ticks. Then you you can use the DateTime.AddTicks method on the DateTime value returned from the TryParseExact method.
I have put together a class to parse a TimeStamp string using this methodolgy and can make a copy of the code available if you are interested in it.
Yeah, its cold and I saw this as an interesting exercise.

Which is very difficult.
The biggest problem starts when you try to parse the Miliseconds directly, as in DateTime.TryParseExact(yyyy-MM-dd\THH:mm:ss.fff) where fff defines the miliseconds. DateTime can't handle any conversion if the amount of 'f' is not equal to the amount of the miliseconds, e.g.
parsing 2014-02-13\15:33:12.12 with DateTime.TryParseExact(yyyy-MM-dd\HH:mm:ss.fff) would return false, which is a crucial problem in my case since the amount of miliseconds may differ between 0 and 100000.
Of course I could populate them prior to the conversion, but then I am better of with my own class where I have full control over the conversion.

This is real simple now especially after I noticed the other overload on TryParseExact that takes an array of formats to test.
string[] formats = { "yyyy-MM-dd\\THH:mm:ss\\Z",
"yyyy-MM-dd\\THH:mm:ss.f\\Z",
"yyyy-MM-dd\\THH:mm:ss.ff\\Z",
"yyyy-MM-dd\\THH:mm:ss.fff\\Z",
"yyyy-MM-dd\\THH:mm:ss.ffff\\Z",
"yyyy-MM-dd\\THH:mm:ss.fffff\\Z",
"yyyy-MM-dd\\THH:mm:ss.ffffff\\Z",
"yyyy-MM-dd\\THH:mm:sszzz",
"yyyy-MM-dd\\THH:mm:ss.fzzz",
"yyyy-MM-dd\\THH:mm:ss.ffzzz",
"yyyy-MM-dd\\THH:mm:ss.fffzzz",
"yyyy-MM-dd\\THH:mm:ss.ffffzzz",
"yyyy-MM-dd\\THH:mm:ss.fffffzzz",
"yyyy-MM-dd\\THH:mm:ss.ffffffzzz"
};
DateTime dt1 = default(DateTime);
bool res1 = System.DateTime.TryParseExact("1985-04-12T20:20:59.100000-00:15",
formats, System.Globalization.CultureInfo.InvariantCulture,
System.Globalization.DateTimeStyles.AdjustToUniversal,
out dt1);
DateTime dt2 = default(DateTime);
bool res2 = System.DateTime.TryParseExact("1985-04-12T20:20:59.100001-00:15",
formats, System.Globalization.CultureInfo.InvariantCulture,
System.Globalization.DateTimeStyles.AdjustToUniversal,
out dt2);
Console.WriteLine(dt1.Kind.ToString());
Console.WriteLine(dt1.ToString("u"));
Console.WriteLine((dt1 < dt2).ToString());
This code works, but has the drawback of loosing the original offsets as everything gets adjusted to UTC.
You can maintain the original offset date by using the DateTimeOffset [^]structure (this structure has all the functionality that I so foolishly recreated by custom parsing).  Oh, well it was fun to see if I could do it.
DateTimeOffset dto1 = new DateTimeOffset();
bool res1b = System.DateTimeOffset.TryParseExact("1985-04-12T20:20:59.100000-00:15",
formats,
System.Globalization.CultureInfo.InvariantCulture,
System.Globalization.DateTimeStyles.AssumeLocal,
out dto1);Notice the change to AssumeLocal. The DateTime and Offset properties can then be used to recreate the original string.

I have a file in which each line has a fixed length 1600 char
but each line has its there are different columns
Line 1 will be like this
RA01XYZ--------------------------------------------------------------------201401231
RA is Record Type
01 is Version
XYZ------------------ is client name
201401231 is date
now 2 line
SR0123456789-------------------------011234567890-
SR is record type
0123456789------------------------- is some number
You see that each line will have its own set of defined columns and it cannot be fixed width
So my question is, is it possible/advisable to apply SSIS on this or create a simple win form application using REGEX to extract and process the data.

Regex? No, Substring(start, length).
Read a whole line, determine the "line type", and then get its data into appropriate objects which you then insert into the db.

Bernhard Hiller wrote: get its data into appropriate objects
Which he may do by using an appropriate regex, so not a really bad start.

ok, but i want a view on processing this type of file using ssis??
is it doable and advisable

Hi my name is vishal.For past 10 days i have been going nuts over of how to create barcode in c# windows forms with sql server 2008 using StrokeScribe control of version 4.3.2. i have done some coding here with 5 group boxes with no success. i have four group boxes
1) group box-1-name:fmeStep1,text:Step 1,visible:true.
It has 8 labels,2 comboboxes,3 textboxes,3 datetimepickers.
2) group box-2-name:fmeBarCode,text:"",visible:true
It has i label,i textbox.
3) group box-3-name:fmeDEntry,text:Dialyzer Entry,visible:true.
It has 2 radio buttons
4) group box-4-name:fmeStep2,text:Step 3,visible=true.
It has i textbox named txtDID,visible=true,enabled=true.1 button,1 strokescribe control of version:4.3.2.,name:barCDialyzer.Given below is properties of barCDialyzer:

You should edit your message, it is almost unreadable as it stands. And try to identify exactly where the problem lies, rather than expecting others to work through code which they have never seen before.

It's a sample database used in a lot of example code by Microsoft and others. You may use it as you wish to build code...

Come on! This is ultimate in lazy. You could have typed "What is the Northwind database" into any search engine and found the answer to that in under 30 seconds.
