please suggest me correct way. thanks

you can use backgroundworker class this:

        string[] images = new string[50];         foreach (var path in images)         {             backgroundworker w = new backgroundworker();             //50 independently async threads             w.dowork += delegate (object s, doworkeventargs args)              {                 upload(args.argument.tostring());             };             w.runworkerasync(path);         }
