      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 );
   }
}

public static void GetPage(String url)

         Uri fileUrl = new Uri("file://"+url);
         // 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..");
         // Release resources of response object.
         myFileWebResponse.Close();

      }
     catch(WebException e)

    }
     catch(Exception e)
    {

     }
}

        ' 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)

Comentarios

El Close método limpia los recursos utilizados por FileWebResponse y cierra el flujo de respuesta mediante una llamada al Stream.Close método .

Nota

El flujo de respuesta debe cerrarse para evitar que se agote el número de recursos del sistema. Puede cerrar el flujo de respuesta llamando a Stream.Close o Close
