You have to check if you can open the file exclusively:

C#

FileStream stream = null;
bool isInUse = false;
                   try
                   {
                       // check if the file can be opened exclusive.
                        using (stream = File.Open(FolderAndFileName, FileMode.Open, FileAccess.Write, FileShare.None))
                       {
                           isInUse = !stream.CanWrite;
                       }
                   }
                   catch (Exception err)
                   {
                        isInUse = true;
                   }
