  • Some other program is using the file. It's as simple as that. Do you have the file open in another copy of the program? Some other program? – siride Jul 31 '16 at 18:34
  • Also, if you are uploading the file to the same place as it currently is, you'll get that error. Make sure your source path and destination path are different. – siride Jul 31 '16 at 18:37
  • @siride No the file is not used by another program and yes both the paths are different – Shashikant Jul 31 '16 at 18:38
  • Well, it is, because you are getting that error. – siride Jul 31 '16 at 18:39

It's probably because you are attempting to copy the file to itself. The call to Combine(), as you have it, is just returning fileName. Change the following line:

string destFile = System.IO.Path.Combine(DestPath, fileName);

to

string destFile = System.IO.Path.Combine(DestPath, System.IO.Path.GetFileName(fileName));

  • @Shashikant - if this answer solved your problems, please be sure to mark as Accepted (click the green checkmark) so that others know this was the correct solution if they come visit later. :) – Tommy Jul 31 '16 at 19:37
  • @seairth done, can you please explain like what that function GetFileName() actually do. – Shashikant Jul 31 '16 at 19:41
  • @Shashikant It returns only the "main_background.jpg" portion of the path stored in `fileName`. – seairth Jul 31 '16 at 19:44
  • So the combine function will not work if we pass the pull path of the file,it will work only when we pass the only file name of the source correct ? – Shashikant Jul 31 '16 at 20:01
  • See MSDN on [Path.Combine(path1, path2)](https://msdn.microsoft.com/en-us/library/fyy7a5kt(v=vs.110).aspx): _If path2 includes a root, path2 is returned_. – Patrice Gahide Jul 31 '16 at 20:19
