In WPF how do I specify the path to a file nested in a Directory using XAML?

I am trying to do this...

<Image x:Name="imgGroupImage" Source="Images\unlock.png" Margin="0,0,5,0" />

But I get this error...

Cannot convert string 'Images\unlock.png' in attribute 'Source' to object of type 'System.Windows.Media.ImageSource'. Cannot locate resource 'forms/images/unlock.png'. Error at object 'System.Windows.HierarchicalDataTemplate' in markup file 'Fuse;component/forms/mainwindow.xaml' Line 273 Position 51.

As you can see, my form that includes this XAML is in a folder named Forms. My Images are in a folder named Images. How do I map from Forms to Images?

I tried Source="..Images\unlock.png" which does not work in WPF.

Any help?

In order to use resource located in folder different that the one where your XAML is, do this: 

<Image Source="pack://application:,,,/Resources/image.png"/>

Where Resources is name of directory which you want to use resources from and image.png is name of image to display. Answer found thanks to @matt-hamilton and @brian-hinchey and their mention of Pack URI.
Works perfectly with your own Converters. You just have to return string matching schema above.

Have you tried setting the source to a BitmapImage?

<Image x:Name="imgGroupImage" Margin="0,0,5,0"  >
   <Image.Source>
      <BitmapImage UriSource="Images/unlock.png" />
   </Image.Source>
</Image>

I believe the default type of Uri for UriSource is a relative Uri, which works off the application's base class. You might find you can configure the BitmapSource a bit easier than trying to find the exact way you have to enter the file path in the Source attribute.

  1. Add your image to the Project in VS
  2. Right click on that image unlock.png
  3. Go to Context menu /Properties
  4. Change Build Action to Resource

Thats it :-)

Try slashes rather than backslashes, and use an absolute path by leading with a slash:

Source="/Images/unlock.png"

That generally works for me.

Failing that, take a look at Pack URIs.
