在代码后面设置WPF图像控件的源

Question

Recently I've been strugling with setting the Setting the source of WPF Image control inside code.

I've tried something like:

Image.Source = new BitmapImage(new Uri(@"/hrc.Hands;component/Images/BlueFolder.png", UriKind.RelativeOrAbsolute));

But it doesn't seem to work and thorws Object reference not set to an instance of an object exception. Here's the screenshot of the path to my image inside hierachy:

You can use..

var imageSource = new Uri(@"pack://application:,,,/" + Assembly.GetExecutingAssembly().GetName().Name + ";component/" + "Images/BlueFolder.png", UriKind.Absolute);
Image.Source = imageSource;

Also, make sure that BlueFolder.png is set as a Resource . Right click the image, and select Properties to do this.
