I can see this post was viewed over 46 000 times   I would bet many of the 46 000 viewers are asking this question simply because they just want the file name    and these answers can be a rabbit hole if you cannot make your substring verbatim using the at sign   If you simply want to get the file name  then there is a simple answer which should be mentioned here  Even if it s not the precise answer to the question   result   Path GetFileName fileName     see https   msdn microsoft com en-us library system io path getfilename v vs 110  aspx

You can get the position of the last - with str LastIndexOf  -    So the next step is obvious   var result   str Substring str LastIndexOf  -     1     Correction   As Brian states below  using this on a string with no dashes will result in the same string being returned
