Application.GetResourceStream Method (StreamResourceInfo, Uri)
Returns a resource file from a location in the specified zip package.
Assembly: System.Windows (in System.Windows.dll)
'Declaration Public Shared Function GetResourceStream ( _ zipPackageStreamResourceInfo As StreamResourceInfo, _ uriResource As Uri _ ) As StreamResourceInfo
- 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.
The 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.
Imports System.Windows.Resources Imports System.IO Imports System.Windows.Media.Imaging Partial Public Class PageLong Inherits UserControl Private WithEvents webClient As New WebClient Public Sub New() InitializeComponent() ' 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. Dim uri As New Uri("ZIPPackageWithImage.zip", UriKind.Relative) ' Download the zip package. webClient.OpenReadAsync(uri) End Sub Private Sub webClient_OpenReadCompleted(ByVal sender As Object, _ ByVal e As OpenReadCompletedEventArgs) _ Handles webClient.OpenReadCompleted ' Extract the desired image from the zip package. Dim zipPackageStream As Stream = e.Result Dim image As Image = LoadImageFromZipPackage( _ "ImageInZipPackage.png", zipPackageStream) Me.stackPanel.Children.Add(image) End Sub Public Function LoadImageFromZipPackage( _ ByVal relativeUriString As String, _ ByVal zipPackageStream As Stream) 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 zipPackageSri As New StreamResourceInfo(zipPackageStream, Nothing) Dim imageSri As StreamResourceInfo = _ Application.GetResourceStream(zipPackageSri, uri) ' Convert the stream to an Image. Dim bi As New BitmapImage() bi.SetSource(imageSri.Stream) Dim img As New Image() img.Source = bi Return img End Function End Class
