How to reference image source files that are packaged with my metro style app?
Solution 1
new Uri("ms:appx");
I think that's the source of the original problem. The scheme is ms-appx not ms:appx
Bad URI: ms:appx://Assets/Images/back.png
Good URI: ms-appx://Assets/Images/back.png
But using FrameworkElement is not a bad idea, if you're really trying to scope something like its parent - even if both work, the latter is probably may be clearer to the reader of your intent (assuming that's your intent).
Solution 2
Yes you are right, this is the answer to your question.
img.Source = ImageFromRelativePath(this, "Assets/Images/back.png");
public static BitmapImage ImageFromRelativePath(FrameworkElement parent, string path)
{
var uri = new Uri(parent.BaseUri, path);
BitmapImage bmp = new BitmapImage();
bmp.UriSource = uri;
return bmp;
}

I have a .png file as a content of my application. When I bind it in xaml like this
<ImageBrush x:Key="BtnBackImageBrush" ImageSource="/Assets/Images/back.png" />
everything ok.
I read this article and when I try to get access to this .png programmatically I get an error.
Code I use:
Uri baseUri = new Uri("ms:appx"); Image img = new Image(); img.Source = new BitmapImage(new Uri(baseUri, "/Assets/Images/back.png")); img.ImageFailed += (sender, args) => new MessageDialog("Error").ShowAsync();
And my question is how to reference image source files that are packaged with my metro style app?
Thanks for advices.
UPDATE: I found answer! We need set baseUri using parent FrameworkElement instead of setting it manually. For example:
// Usage myImage.Source = ImageFromRelativePath(this, "relative_path_to_file_make_sure_build_set_to_content"); public static BitmapImage ImageFromRelativePath(FrameworkElement parent, string path) { var uri = new Uri(parent.BaseUri, path); BitmapImage result = new BitmapImage(); result.UriSource = uri; return result; }
Thanks for this article.
