Blend（XAML）不支持Image.Source中的png图像

Question

I try to show an Image in my WPF application and added the following code:

<Image Height="20" Width="20" DockPanel.Dock="Left" Source="pack://application:/Testapp.Model/Resources/Icons/systemEnviromentActor.png"/>

However I get the error that blend does not support this type of Image. Microsofts page says that Image does support .png .

I created the Image with Paint.net

Answer 1

The URI is invalid. A valid Resource File Pack URI would look like shown below, where Testapp.Model is an assembly name.

pack://application:,,,/Testapp.Model;component/Resources/Icons/systemEnviromentActor.png

If the image file is in the same assembly, you could write it as

pack://application:,,,/Resources/Icons/systemEnviromentActor.png

In XAML, you could then even omit the prefix, and just write

Source="/Resources/Icons/systemEnviromentActor.png"

Also make sure that the Build Action of the image file is set to Resource .
