void GetPage( String^ url )
{
   try
   {
      Uri^ fileUrl = gcnew Uri( String::Concat( "file://", url ) );
      // Create a FileWebrequest with the specified Uri.
      FileWebRequest^ myFileWebRequest = dynamic_cast<FileWebRequest^>(WebRequest::Create( fileUrl ));
      // Send the 'fileWebRequest' and wait for response.
      FileWebResponse^ myFileWebResponse = dynamic_cast<FileWebResponse^>(myFileWebRequest->GetResponse());
      // Process the response here.
      Console::WriteLine( "\nResponse Received::Trying to Close the response stream.." );
      // Release resources of response Object*.
      myFileWebResponse->Close();
      Console::WriteLine( "\nResponse Stream successfully closed." );
   }
   catch ( WebException^ e ) 
   {
      Console::WriteLine( "\r\nWebException thrown. The Reason for failure is : {0}", e->Status );
   }
   catch ( Exception^ e ) 
   {
      Console::WriteLine( "\nThe following Exception was raised : {0}", e->Message );
   }
}

         // Create a FileWebrequest with the specified Uri.
         FileWebRequest myFileWebRequest = (FileWebRequest)WebRequest.Create(fileUrl);
         // Send the 'fileWebRequest' and wait for response.
         FileWebResponse myFileWebResponse = (FileWebResponse)myFileWebRequest.GetResponse();
         // Process the response here.
         Console.WriteLine("\nResponse Received.Trying to Close the response stream..");

        ' Send the 'fileWebRequest' and wait for response.
        Dim myFileWebResponse As FileWebResponse = CType(myFileWebRequest.GetResponse(), FileWebResponse)
        ' Process the response here
        Console.WriteLine(ControlChars.Cr + "Response Received.Trying to Close the response stream..")
        ' The method call to release resources of response object.
        myFileWebResponse.Close()
        Console.WriteLine(ControlChars.Cr + "Response Stream successfully closed")
    Catch e As WebException
        Console.WriteLine(ControlChars.Lf + ControlChars.Cr + "The Reason for failure is : {0}", e.Status)
    Catch e As Exception
        Console.WriteLine(ControlChars.Cr + "The following exception was raised : {0}", e.Message)
    End Try

Remarques

La Close méthode nettoie les ressources utilisées par un FileWebResponse et ferme le flux de réponse en appelant la Stream.Close méthode.

Notes

Le flux de réponse doit être fermé pour éviter de manquer de ressources système. Vous pouvez fermer le flux de réponse en appelant ou Stream.CloseClose
