void webclient_downloaddatacompleted(object sender, downloaddatacompletedeventargs e)         {             mprbprogress.visibility = viewstates.gone;              var bytes = e.result;              if(bytes != null && bytes.length > 0)             {                 var imagebitmap = bitmapfactory.decodebytearray(bytes, 0, bytes.length);                 mimgimage.setimagebitmap(imagebitmap);             }         }
