Hey guys,

Now i want to ask you someting about creating directory. I know how to create dir with names that i write in my code but i want to create directory that name is date of today. Here is my code;

C#

DateTime now1 = new DateTime();
           now1 = DateTime.Today;
           string bugun = now1.ToString();


           if (!Directory.Exists(@"c:\data\" + bugun))
               Directory.CreateDirectory(@"c:\data\" + bugun);

The error code is "An unhandled exception of type 'System.NotSupportedException' occured in mscore.lib" Something is wrong about directory codes.

What is your date separator?
I'd suggest to use something like this:

string myDate = DateTime.Today.ToString("yyyyMMdd");
Directory.CreateDirectory(initialDir + myDate);

C#

string bugun = DateTime.Now.ToString("yyyyMMdd"); 
if (!Directory.Exists(@"c:\data\" + bugun))
{
   Directory.CreateDirectory(@"c:\data\" + bugun);
}

If you use a debugger it says: The given path's format is not supported.

bugun is 12.12.2014 00:00:00

So you are trying to create a path called c:\data\12.12.2014 00:00:00

':' is not allowed in a path name.

Change the format of your date e.g.:

C#

string bugun = now1.ToString("yyyy-MM-dd");

The resulting path will be: C:\data\2014-12-12

Solution 1

You should use the following code to combine strings into a path

colorPath = System.IO.Path.Combine(@"c:\data\", bugun);

The Combine method takes care of adding or removing backslashes where necessary.
DateTime.Today returning date which contains '/',spaces and/or special character. Combine method will take care of that.

Unfortunately your code results in an 'System.NotSupportedException' exception.
It still says: "The given path's format is not supported"
I thought it worked, because I still had "string bugun = now1.ToString("yyyy-MM-dd");"
in my code.
