WPF: Convert ImageSource to Stream

How to convert an image source with URI /ReferencedAssembly;component/default.png to Stream?开发者_运维问答

Thank you

This should work:

var uri = new Uri("/ReferencedAssembly;component/default.png", UriKind.Relative);
var streamInfo = System.Windows.Application.GetResourceStream(uri);
var stream = streamInfo.Stream;
