Actually, I think you mean your list is called mResults, so in that case I would do...
mResults.Sort((i, j) => { return i.Field2.CompareTo(j.Field2); });

This article[^] tells you how to do it without LINQ.

Nah. It's crap.  Only kidding - it's a good article.
A small critique - the plural of criterion is criteria, so you have s singular of "the criterion is...", where the plural would be "Multiple sort criteria are easy to implement". A criterium is actually a bike race.

Thanks Pete.
In Dutch we use the Latin word criterium for both; English apparently has borrowed the Greek word κριτήριο; all fixed now.

I am confused with the process to export datagridview data to excel or pdf format. Could somebody help me on this please?
Thank you
|
|
|
|
|
I am sure there is no need to shout. To export data to excel look up
ADO.Net or
Excel Interop . to export data to pdf try iTextSharp library. In future you don't need to use bold letters. Most people in these forums can read quite fine.
|
|
|
|
|
For Excel, just put it on the clipboard. (DataGridView.GetClipboardContent.)
For PDF there is no obvious meaning for what you want, never mind a method to do it. PDF is a display format not a data table one. If you want to create a PDF which has within it some text and lines that makes it look like a table, you can do that yourself (or find a library that does it).

Hi,
I have two classes say Class A and Class B. I am trying to find how
do I get reference the loaded instance of Class A in Class B.
I do not want to get a new instance of Class A. I want to be able to
reference to the loaded instance and use the loaded methods and properties.
Class A
{
...
Class A myClass = New Class A();
...
...
Class B clsb = New Class B();
clsb.DoSomething(int a, int b)
}
Class B
{
...
public void DoSomething(int a, int b)
{
....
//I want to be able to reference to the loaded instance which is 'myClass' of the Class A. (not a new instance)
}
}
Can some one please help me with this.
Thanks,
L

ClassA should provide a static method or a static property which returns the instance created inside it. This method/property will help others access that instance.
|
|
|
|
|
If having a static reference (or the Singleton pattern, basically the same thing) is inappropriate, you could pass it in in the constructor or as a method parameter on class B.
I'm surprised this works, though - maybe it's the pseudo-code you've presented, but this:
public class ClassA()
{
private ClassA myClass = new ClassA();
}
is the same as:
public class ClassA()
{
private ClassA myClass = null;
public ClassA()
{
myClass = new ClassA();
}
}
Won't this end up with a stack overflow?

Why not just run it and see for yourself. I guess it will.

It was more intended as a rhetorical question, like a "have you thought about this...?" 'sides, too busy hating on BizTalk to play around

Pass it to the constructor or a property.
B b = new B() ;
A a = new A ( b ) ;
or
a.B = b ;

Hi,
You need to use the Singleton pattern to achieve this. Please find the example below
public class A
{
private static A _instance;
private A()
{}
public static A GetInstance()
{
if(_instance == nulll)
_instance = new A();
return _instance;
}
}
public class B
{
public void Somemethod()
{
A a = A.GetInstance();
.
.
.
do somethig
.
.
}
}
Note that we make the constructor of class A private. And class A holds a instance of itself in _instance variable. This is for to make sure that an out side method cannot create an instance of A. Then we will provide a static method in class A like GetInstance where we create a new instance if an instance is already not exist and return the current instance
Hope this helps

No, never a singleton, especially with .net languages; they're not needed and generally a symptom of poor design. I have never found a situation that wuold benefit from a singleton.

In .net everyone has access to your privates.

Hi,
I want to separate number and date and time from a string in c#. here is an example:
+CMGR: "REC READ","+923365483536",,"10/09/15,08:16:11+20"
from this i want to put cell number in one array and date and time in another.I dont know how to do this.
Thanks for any kind of help in advance
Regards,
Aeman

Well, you could always use a string split on this based on the commas and take the array items at index 1 and index 3.
|
|
|
|
|
index 3 and 4!
I cannot remember: What did I before google?
|
|
|
|
|
So cell isn't stored in the bit +9....? Index 3 is an empty string in his example.
Nevermind - I see what you're saying. I'd missed the , in the date.
I'm not a stalker, I just know things. Oh by the way, you're out of milk. Forgive your enemies - it messes with their heads

You could use a regular expression but then you may end up with not one problem but two 
using System.Text.RegularExpressions;
...
string txt = "+CMGR: \"REC READ\",\"+923365483536\",,\"10/09/15,08:16:11+20";
Match m = Regex.Match(txt, @"[0-9]{2}/[0-9]{2}/[0-9]{2},[0-9]{2}:[0-9]{2}:[0-9]{2}");
if(m.Success)
{
String date = m.Value.Replace(",", " ");
DateTime dt = DateTime.Parse(date);
}
The snippet above should work but you may want to refine the expression. I just hacked that one up quickly
"You get that on the big jobs."

May I humbly suggest Rive[^]?

Try to use regular expression,MAN.
Hope this helps.
Hi, i am from china.Like to make friends with you from all of the world.

It's very easy
First store the entire string in a string variable
and then use the split method and assign it to a character array
split(",,")
and from that array fetch the appropriate value like
string s="+CMGR: "REC READ","+923365483536",,"10/09/15,08:16:11+20";
char[] temp=s.split(",,");
now your temp[1] consists both time and date.
if you want separate both use the same technique.
