将BitmapImage转换为System.Windows.Media.Brush

Question

How would I convert a BitmapImage to a System.Windows.Media.Brush ?

I have a BitmapImage imaginatively called bitmap , and I have a Canvas (also imaginatively titled) canvas .

How would I set the value of canvas to the value of bitmap ?

I've tried canvas.Background = bitmap; , but that didn't work: image.Source = bitmap; works for images, but not Canvases: and

ImageSourceConverter imgs = new ImageSourceConverter(); canvas.SetValue(Image.SourceProperty, imgs.ConvertFromString(bitmap.ToString()));

didn't work either.

All of these worked with images, however.

Maybe something with bitmap.ToString() would work?

Answer 1

Create an ImageBrush and use that as the background:

 ImageBrush ib = new ImageBrush();
 ib.ImageSource = bitmap;
 canvas.Background = ib;

Answer 2

只是：

canvas.Background = new ImageBrush(bitmap);
