  NameDescription
Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)

The StreamResourceInfo class is not just for pure application model scenarios. You can use a StreamResourceInfo to process a stream that happens to be a package (a XAP or ZIP file). This is useful if you have returned an asynchronous stream result from a WebClient request and the returned stream is really a package that contains multiple parts. To get at these parts, you must request each of the parts as a URI that you specify in the GetResourceStream call, with the initial package specified as the StreamResourceInfo for the zipPackageStreamResourceInfo parameter.

The following code example demonstrates how to use this class.


using Microsoft.Phone.Controls;
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 PhoneApp1
{
    public partial class MainPage : PhoneApplicationPage
    {
        public MainPage()
        {
            InitializeComponent();

            // 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(
                "/PhoneApp1;component/EmbeddedInApplicationAssembly.png");
            this.stackPanel.Children.Add(img1);

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

        }

        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();
            bi.SetSource(sri.Stream);
            Image img = new Image();
            img.Source = bi;

            return img;
        }
    }
}
