StreamResourceInfo Class
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Provides resource stream information for application resources or other packages obtained through the GetResourceStream method.
Assembly: System.Windows (in System.Windows.dll)
The StreamResourceInfo type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | ContentType | Gets the MIME type of the content in the stream. |
![]() | Stream | Gets the stream that is contained by the resource. |
| Name | Description | |
|---|---|---|
![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.) |
![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | ToString | Returns a string that represents the current object. (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.
Imports Microsoft.Phone.Controls Imports System.IO Imports System.Windows Imports System.Windows.Controls Imports System.Windows.Media.Imaging Imports System.Windows.Resources Partial Public Class MainPage Inherits PhoneApplicationPage Public Sub New() 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. Dim img1 As Image = LoadImage("/PhoneApp1VB;component/EmbeddedInApplicationAssembly.png") Me.stackPanel.Children.Add(img1) ' Load an image resource file included the application package. Dim img2 As Image = LoadImage("IncludedInApplicationPackage.png") Me.stackPanel.Children.Add(img2) End Sub Public Function LoadImage(relativeUriString As String) As Image ' Get the image stream at the specified URI that ' is relative to the application package root. Dim uri As New Uri(relativeUriString, UriKind.Relative) Dim sri As StreamResourceInfo = Application.GetResourceStream(uri) ' Convert the stream to an Image object. Dim bi As New BitmapImage() bi.SetSource(sri.Stream) Dim img As New Image() img.Source = bi Return img End Function End Class
