Question

How to GetResourceStream from absolute uri.

When I am running the below code I am getting null in sri.

StreamResourceInfo sri = Application.GetResourceStream(new Uri("http://----", UriKind.RelativeorAbsolute));
BitmapImage src = new BitmapImage();
src.SetSource(sri.Stream);
// Get WriteableBitmap
WriteableBitmap bitmap = new WriteableBitmap(src);

Any help is highly appreciated.

GetResourceStream method is not for http requests. See the documentation here.

Returns a resource file from a location in the application package.

uriResource Type: System.Uri A relative URI that identifies the resource file to be loaded. If the file has a Build Action of Content, the URI is relative to the application package and you should not use a leading forward slash. If the file has a Build Action of Resource , you can use a leading forward slash, but it is not required.

Resource data is a data compiled into your assembly/package

Basically, there are two types of resources which you can load via that method:

• Files Embedded in the application assembly in the application package Uri("/Application;component/EmbeddedInApplicationAssembly.png")

• Files included in the application package Uri("IncludedInApplicationPackage.png");
