System. Drawing. image data to system. Windows. Media. imagesource (WPF)

1. Use memeorystream

 1 Imagebrush backbrush = New  Imagebrush ();  2 Bitmapimage Bi = New  Bitmapimage ();  3   Bi. begininit ();  4 Memorystream MS = New  Memorystream ();  5 Imove. App. eastonline. properties. Resources. Background. Save (MS, imageformat. BMP ); // System. Drawing. image;  6 Ms. Seek ( 0  , Seekorigin. Begin );  7 Bi. streamsource = MS;  8   Bi. endinit ();  9 Backbrush. imagesource = Imaging. createbitmapsourcefromhbitmap (hbitimage, intptr. Zero, int32rect. empty,  10   Bitmapsizeoptions. fromemptyoptions ());  11 Backbrush. Stretch = Stretch. Fill;  12                   This . Background = backbrush;

 

 

2. Use Imaging

 
Imagebrush backbrush =NewImagebrush (); intptr hbitimage=Imove. App. eastonline. properties. Resources. Background. gethbitmap (); backbrush. imagesource=Imaging. createbitmapsourcefromhbitmap (hbitimage, intptr. Zero, int32rect. Empty, bitmapsizeoptions. fromemptyoptions (); backbrush. Stretch=Stretch. Fill;This. Background = backbrush;
