How to convert a drawing image to the source of a WPF control

This example takes canvas as an example

<Canvas>
<image stretch= "Fill" width= "" "" height= "x:name=" MyImage "/>
</Canvas>

One way:
System.Drawing.Image bmp= ...; A valid image that is initialized by itself
System.IO.MemoryStream ms = new System.IO.MemoryStream ();
Bmp. Save (MS, SYSTEM.DRAWING.IMAGING.IMAGEFORMAT.BMP);//format self-processing, here with bitmap
downlink, initial a imagesource as source of MyImage
System.Windows.Media.Imaging.BitmapImage bi=new System.Windows.Media.Imaging.BitmapImage ();
Bi. BeginInit ();
Bi. Streamsource = new MemoryStream (Ms. ToArray ()); Do not use MS directly
Bi. EndInit ();
Myimage.source = bi; done!
Ms. Close ();

Another method (the more common method):
System.Drawing.Image bmp= ...; A valid image that is initialized by itself
System.Windows.Media.Imaging.BitmapSource bi =
System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap (
Bmp. Gethbitmap (),
IntPtr.Zero,
Int32rect.empty,
Bitmapsizeoptions.fromemptyoptions ());
Above in BMP format for example, other format self-processing
Myimage.source = bi; done!

Refer to the following methods of System.Windows.Interop.Imaging:
Createbitmapsourcefromhbitmap ()//Get ImageSource from Hbitmap
Createbitmapsourcefromhicon ()//Get ImageSource from Hicon
Createbitmapsourcefrommemorysection ()//Get ImageSource from Hmem

The following are additional examples of code snippets in the following work:

Captureimagetool capture = new Captureimagetool ();
if (capture. ShowDialog () = = System.Windows.Forms.DialogResult.OK)
{
System.Drawing.Image Image = Capture. Image; Get drawing image
Bitmap bmp = new Bitmap (image); Get bitmap
System.Windows.Media.Imaging.BitmapSource Bmpresource =
System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap (BMP. Gethbitmap (),
IntPtr.Zero,
Int32rect.empty,
Bitmapsizeoptions.fromemptyoptions ()); to bitmap resource
Image1.               Source = Bmpresource; Done
}
