Hello,
I am trying to add DataTime.Now.ToString() to a file name but I get an
exception while doing it that such format is not supported in path. How
can I solve this and cast this issue?

Thank you!

Standard DateTime Format contains '/' signs, which are not allowed in
path, so you have to use ToString with format parameter (you can see in
MSDN help how to specify wanted format).
 
Check your filename against System.IO.Path.GetInvalidPathChars() and
System.IO.Path.GetInvalidFileNameChars(). More than likely you have at
least a couple of violations. A fix I have used is to use
DateTime.Now.Ticks.

DateTime dt = System.DateTime.Now;
string s1 = dt.ToShortDateString().ToString
(System.Globalization.CultureInfo.CurrentCulture);
string s2 = dt.ToString
(System.Globalization.CultureInfo.CurrentCulture);

s1 = s1.Replace("/", null);
s1 = s1.Replace(":", null);
s2 = s2.Replace("/", null);
s2 = s2.Replace(":", null);

Console.WriteLine(s1);
Console.WriteLine(s2);

The above code snippet may help

There are multiple ways to do this, obviously. One of my favorite ways,
which also enables sorting to continue through the date (in chronological
order):

DateTime.Now.ToString("yyyyMMdd_hhmmss"); // includes time
DateTime.Now.ToString("yyyyMMdd"); // does not include time

Then append one of the above methods to the file name (before adding the
extension), then add the extension and voila! Filename + valid date :)
