Application.GetResourceStream Method (Uri)

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

Namespace:  System.Windows
Assembly:  System.Windows (in System.Windows.dll)

public static StreamResourceInfo GetResourceStream(
	Uri uriResource


Type: System.Uri
A relative URI that identifies the resource file to be loaded. The URI is relative to the application package and does not need a leading forward slash.

Return Value

Type: System.Windows.Resources.StreamResourceInfo
A StreamResourceInfo that contains the stream for the desired resource file.


The application class is not initialized.


uriResource is an absolute URI.


uriResource is null.

The GetResourceStream method allows you to load an arbitrary resource file from one of the following locations:

  • Embedded in the application assembly in the application package.

  • Embedded in a library assembly that is included in the application package.

  • Included in the application package.

The following code shows how to use GetResourceStream to load an image resource file from these three locations.

Run this sample

<UserControl x:Class="SilverlightApplication.PageShort"

    <StackPanel x:Name="stackPanel" />


using System; // Uri
using System.IO; // Stream
using System.Windows; // Application
using System.Windows.Controls; // TextBlock, Image
using System.Windows.Media.Imaging; // BitmapImage
using System.Windows.Resources; // StreamResourceInfo

namespace SilverlightApplication
    public partial class PageShort : UserControl
        public PageShort()

            // Load image resource files included in the application package 
            // and resources that are embedded in assemblies included in the
            // application package.

            // Load an image resource file embedded in the application assembly.
            Image img1 = LoadImage(

            // Load an image resource file included the application package.
            Image img2 = LoadImage("IncludedInApplicationPackage.png");

            // Load an image resource file embedded in a library assembly, 
            // which is included in the application package.
            Image img3 = LoadImage(

        public Image LoadImage(string relativeUriString)
            // Get the image stream at the specified URI that
            // is relative to the application package root.
            Uri uri = new Uri(relativeUriString, UriKind.Relative);
            StreamResourceInfo sri = Application.GetResourceStream(uri);

            // Convert the stream to an Image object.
            BitmapImage bi = new BitmapImage();
            Image img = new Image();
            img.Source = bi;

            return img;
