Application.GetResourceStream Method (StreamResourceInfo, Uri)


Returns a resource file from a location in the specified zip package.

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

public static StreamResourceInfo GetResourceStream(
	StreamResourceInfo zipPackageStreamResourceInfo,
	Uri uriResource


Type: System.Windows.Resources.StreamResourceInfo
A StreamResourceInfo that contains the zip package stream with the desired resource file.
Type: System.Uri
A relative URI that identifies the resource file to be extracted from the zip package. 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.


zipPackageStreamResourceInfo is null.


uriResource is null.

The GetResourceStream(StreamResourceInfo, Uri) method provides more flexibility than GetResourceStream(Uri) by allowing you to extract a resource file from an arbitrary zip package.

The following example shows how to extract an image resource file from a zip package that is located at the Silverlight application's site of origin.

Run this sample

<UserControl x:Class="SilverlightApplication.PageLong"

    <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.Net; // WebClient
using System.Windows.Resources; // StreamResourceInfo

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

            // Load an image resource file that is included in a ZIP package
            // at the site of origin.

            // Specify the zip package with the image resource to get.
            Uri uri = new Uri("", UriKind.Relative);

            // Download the zip package.
            WebClient webClient = new WebClient();
            webClient.OpenReadCompleted += new OpenReadCompletedEventHandler( 

        void webClient_OpenReadCompleted(object sender, 
            OpenReadCompletedEventArgs e)
            // Extract the desired image from the zip package.
            Stream zipPackageStream = e.Result;
            Image image = LoadImageFromZipPackage(
                "ImageInZipPackage.png", zipPackageStream);

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

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

            return img;
