我只是在同一个问题上挣扎了很长一段时间,我认为原版中出现问题的部分原因是缺少“组件”这个词。例如,我有
myBitmapImage.UriSource = new Uri(@"pack://application:,,,/MyApp;images/mona2.jpg");
但应该有
... = new Uri(@"pack://application:,,,/MyApp;component/images/mona2.jpg");
The word "component" is not part of the pathname, despite its appearance -- it's a string literal that has to be there. Why? Someone thought it'd be a good idea, I guess.
And for those struggling with another part of the thing, what about "MyApp"? That's the name of the Assembly. Right-click on your project name, select "Properties...", and under the "Application" tab you'll see the "Assembly name:" field.
If you don't feel like searching for that (or worry that it might change, breaking your code), you can do this:
String appUri = @"pack://application:,,,/" +
System.Reflection.Assembly.GetEntryAssembly().GetName().Name + ";";
String path = appUri + "component/images/mona2.jpg";
myBitmapImage.UriSource = new Uri(path);
Not very pretty code, I admit -- it can clearly be shortened -- but it'll gets you where you need to go, I hope. Remember to set the "Build" property on your image file to "Resource"!
