Getting a URI from a XAML type

[Paul Stovell]

Hi all,

I'm trying to make a bit of code like this work:

  Type pageType = typeof(Page1);
  Uri pageUri = GetPackUriForType(pageType);

The problem is I can't find any way of getting the URI from a type.

In the .g.cs files that are built, the URI is embedded as part of the InitializeComponent:

        public void InitializeComponent() {
            if (_contentLoaded) {
                return;
            }
            _contentLoaded = true;
            System.Uri resourceLocater = new System.Uri("/PageCollection;component/pages/page1.xaml", System.UriKind.Relative);
           
            #line 1 "..\..\..\Pages\Page1.xaml"
            System.Windows.Application.LoadComponent(this, resourceLocater);
           
            #line default
            #line hidden
        }

But that URI doesn't appear to be public anywhere. I know IUriContext can be used at runtime, but I'm trying to avoid instantiating the type just to get its URI.

I was considering using using ResourceReader and Assembly.GetManifestResourceStream to get all the BAML resources and implement a dumb BAML reader, but that seems a little dangerous.

The only half decent solution I can come up with is to try to assume the URI using conventions based on the namespace. But that's whack!

Sounds like a job for T4 Paul. :)
Prompted by your question, I've incorporated the generation of pack
URIs for all XAML files into the T4 Metadata generation stuff I did a
while ago. Seems to be working ok. I just blogged about it:

Not to be a Johnny-Come-Lately, seeing as this mail was from 2009, but I thought I needed this functionality recently and came across this old thing.  I ended up prototyping this function, quick and dirty like, before realizing I didn't need it.

Anyways, I put it up on codepaste here for posterity: http://codepaste.net/439f6u
