multithreading - C#, Thread, Memory -


today know how save image stream (really in memory it's possible don't use appropriate term) , read thread.

to think proceed these steps : - in first thread : 1 - create image object (system.drawing) file 2 - create thumbnail 3 - save thumbnail stream (system.io) 4 - send stream object second thread.

b - in second thread : 1 - receive stream first thread 2 - create bitmapimage object stream 3 - displaying on ui. (wpf)

thks.

i've retrieve part of code show did :

in thread check images in folders :

public void createimgobj(object sender) {     try     {         filestream fs = file.open((string)sender, filemode.open);         bitmap dimg = new bitmap(fs);         memorystream ms = new memorystream();         dimg.save(ms, system.drawing.imaging.imageformat.jpeg);         bitmapimage bi_img = new bitmapimage();         bi_img.begininit();         bi_img.streamsource = new memorystream(ms.toarray());         bi_img.endinit();         evt_send_img(bi_img);     }     catch (exception e)     {         evt_error(e);     } } 

in ui thread :

    private void img_recieve(object sender)     {         try         {             dispatcher.begininvoke(dispatcherpriority.normal, new action(() =>                  {                      items.add(new img { img_in = (bitmapimage)sender });                  }));         }         catch (exception e)         {             messageerreur(e);         }     } 

note : "img_recieve" execute "evt_send_img";

thks
