DateTime /File question

[csharpula csharp]

Hello,
I am trying to add Date and Current time to a name of a log file. I
tried doing this:

string logDateExtentio n = DateTime.Now.To ShortDateString ().ToString() +
DateTime.Now.To ShortTimeString ().ToString();

string logName = Data.Name + Data.ProductNam e + logDateExtentio n;

And this throws exception during the debug that the name is not legal
probably because of the ":" or "/" . Which format of date will work for
this purpose?

Thanks!

My suggestion would be someting like YYYYMMDD (maybe separate them using
underlines) because that also sorts well.

Use e.g.

logDateExtensio n = DateTime.Now.To String("yyyyMMd d");

or

logDateExtensio n = DateTime.Now.To String("yyyy_MM _dd");

Re: DateTime /File question

You may want to avoid using yyyymmdd and the like if your application needs
to use the user's preference / locale for formatting. In which case, use
"g" as the format string to combine short date and short time.

Check out my article on DateTime manipulation, which explains the various
formatting options for more info.
