Application.GetContentStream returns null for content Uri

Question

I have file "sample.xml" in my project set as content.

I am running this code:

  Uri uri = new Uri("/sample.xml", UriKind.Relative);
  StreamResourceInfo contentStream = Application.GetContentStream(uri);

Why it returns null contentStream?

Answer 1

It means probably that it does not find the file. Is the path correct?.

Return Value

Type: System.Windows.Resources.StreamResourceInfo

A StreamResourceInfo that contains a content data file that is located at the specified Uri. If a loose resource is not found, null is returned.

Answer 2

You must set file's Build Action as Content, and Copy To Output Directory to Copy Always or Copy if newer.
