Beispiele

Im folgenden Beispiel wird die- MapPathSecure Methode verwendet, um den physischen Pfad eines virtuellen Verzeichnisses des enthaltenden- Page Objekts oder des-Objekts abzurufen UserControl .The following example uses the MapPathSecure method to obtain the physical path of a virtual directory of the containing Page or UserControl object.

// An HttpException occurs if the server control does not,;
// have permissions to read the resulting mapped file. 
     output.Write("The Actual Path of the virtual directory : "+
     MapPathSecure(TemplateSourceDirectory)+"<br>");

    // Get all the files from the absolute path of 'MyControl';
    // using TemplateSourceDirectory which gives the virtual Directory.
        string [] myFiles=
        Directory.GetFiles(MapPathSecure(TemplateSourceDirectory));
        output.Write("The files in this Directory are <br>");

         // List all the files.
         for (int i=0;i<myFiles.Length;i++)
            output.Write(myFiles[i]+"<br>");
' An HttpException occurs if the server control does not,;
' have permissions to read the resulting mapped file.
output.Write("The Actual Path of the virtual directory : " & _
            MapPathSecure(TemplateSourceDirectory) & "<br>")

' Get all the files from the absolute path of 'MyControl';
' using TemplateSourceDirectory which gives the virtual Directory.
Dim myFiles As String() = Directory.GetFiles(MapPathSecure(TemplateSourceDirectory))
output.Write("The files in this Directory are <br>")

' List all the files.
Dim i As Integer
For i = 0 To myFiles.Length - 1
   output.Write(myFiles(i) & "<br>")
Next i

Hinweise

Diese Methode kann nur von Server Steuerelementen verwendet werden, die über Berechtigungen zum Lesen von Dateien verfügen und die Teil von vollständig vertrauenswürdigen dll-Dateien sind, z. b. System.Web.dll.This method can only be used by server controls that have permissions to read files and which are part of fully trusted .dll files, such as System.Web.dll. Dies trägt dazu bei, Sicherheitsverletzungen zu verhindern.This helps prevent security breaches.
