Re: DateTime Hour Minute Question [modified] - C# Discussion Boards

3-May-08 22:38

Hi Guys. I am using DateTime.Today.ToString("ddMMyyyyhhmmss") as part of my file name. I get the correct date and hour returned but the minute and seconds seem to default to 0000. Any idea why?

StreamWriter sw = new StreamWriter(@"C:\SOLZ_PROV_" + DateTime.Today.ToString("ddMMyyyyhhmmss") + ".txt");

Ah, yet again I have answered my Own Question.

DateTime.Now.ToString("ddMMyyyyhhmmss") seems to work just fine.

Hi again,

four remarks this time:

1.
if you were to change the order to "yyyyMMddhhmmss" then the alphabetical order
would be the same as the chronological order, which makes life easier.

2.
you can embed some more characters in the date format string, the ToString() does not
mind about some characters such as an underscore. it just copies them to the output, e.g. I often use "_yyyyMMdd_hhmmss" to get a filename that is more readable.

3.
you don't have to try and do everything in a single line; splitting a statement in two
or three smaller statements yields more readable code, and facilitates debugging, since
now you can set breakpoints on the parts, and watch intermediate results.

4.
if your code is executed repeatedly, you might generate the same filename more than once,
since a modern CPU can do a lot in one second. Even adding milliseconds may be insufficient
since the milliseconds don't get incremented by one, as you might expect; instead they
increase by a larger number but at a lower frequency. For more on this, read my timers
article. A possible remedy is to insert a Thread.Sleep() so the time advances before
you have a chance to generate yet another filename (assuming single-thread use here).

Smile | :)

Thanks Luc. In South Africa we use "ddMMyyyy" as date format. I wa using DateTime.Today which consistantly returned the correct date but the time as 120000 which is probably the start of the day. When I changed to DateTime.Now it returned the time correctly.

I expect to only create one file per day so I should be OK but I wanted to add the date time to show when the report was generated.

I will take this advice and use it. I usually do that.

Thanks again mate. Much appreciated. I try and learn everyday and browsing the posts and Boards helps loads.

It takes a little time to create a file, but the time it takes is enough to pretty much guarantee a unique name every time, especially if your code is performing exception handling (which it should), and properly closing the file (which it should). If you include the millisecond portion of the date time, you should be good to go. Besides, if you think there's a chance of it, the simple solution is to insert the line Thread.Sleep(25); just before you create the file. Doing so guarantees a unique filename using the date/time naming method, and it will introduce unnoticeable latency in your code.

If you don't really care what the file name is as long as it's unique, use a GUID for the name. A GUID is guaranteed to be unique no matter how many you create in a given second.

CPU and RAM Usage

Good Day everyone,

Is it possible to get the total CPU and RAM usage of your application and display it on your form?

Thanks! Smile | :)

It is said that the most complex structures built by mankind are software systems. This is not generally appreciated because most people cannot see them. Maybe that's a good thing because if we saw them as buildings, we'd deem many of them unsafe.

Hi. There are a few good articles here on CP. Have a look at the below link.

The first Article is a good one to look at I think.
