You can test available disk space using:
DriveInfo di= new DriveInfo("C:");
long freeSpace = di.TotalFreeSpace;
and the exeption would be IOException.

Probably better to test you have space available before attemting the write though.

You can add the general error, and after you got the right error you can perhaps specify it a little bit better (I'm not sure if there is a specific diskfull-exception)
Example
try
    {
      // We're simply copying a file here.
      System.IO.File.Copy(strFile, strFile + ".new");
    }
    catch (Exception ex)
    {
      Console.WriteLine("Failed to copy the file: " +  ex.Message);
    }

It should be IOException.
You can test it out easily by writing to a floppy drive or USB thumbdrive (which is near full) ;)

If you are unsure, follow what Dhaest suggested by catching a generic exception and simulate the disk full scenario. Then you can find out the Exception type by putting a breakpoint on the catch line and open your "Watch" panel in VS.
