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. This helps prevent security breaches.

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>");
