{
    try
      {	
            // Creates an HttpWebRequest for the specified URL.
            HttpWebRequest myHttpWebRequest = (HttpWebRequest)WebRequest.Create(url);
            // Sends the HttpWebRequest and waits for a response.
            HttpWebResponse myHttpWebResponse = (HttpWebResponse)myHttpWebRequest.GetResponse();
            if (myHttpWebResponse.StatusCode == HttpStatusCode.OK)
               Console.WriteLine("\r\nResponse Status Code is OK and StatusDescription is: {0}",
                                    myHttpWebResponse.StatusDescription);
            // Releases the resources of the response.
            myHttpWebResponse.Close();
        }
    catch(WebException e)
       {
            Console.WriteLine("\r\nWebException Raised. The following error occurred : {0}",e.Status);
       }
    catch(Exception e)
    {
        Console.WriteLine("\nThe following Exception was raised : {0}",e.Message);
    }
}

Public Shared Sub GetPage(url As [String])
   Try
        ' Creates an HttpWebRequest with the specified URL.
        Dim myHttpWebRequest As HttpWebRequest = CType(WebRequest.Create(url), HttpWebRequest)
        ' Sends the request and waits for a response.
        Dim myHttpWebResponse As HttpWebResponse = CType(myHttpWebRequest.GetResponse(), HttpWebResponse)
        If myHttpWebResponse.StatusCode = HttpStatusCode.OK Then
            Console.WriteLine(ControlChars.Lf + ControlChars.NewLine + "Response Status Code is OK and StatusDescription is: {0}", myHttpWebResponse.StatusDescription)
        End If
        ' Release the resources of the response.
        myHttpWebResponse.Close()
    
    Catch e As WebException
        Console.WriteLine(ControlChars.Lf + ControlChars.NewLine + "Exception Raised. The following error occurred : {0}", e.Status)

Opmerkingen

De StatusCode parameter is een getal dat de status van het HTTP-antwoord aangeeft. De verwachte waarden voor de status worden gedefinieerd in de HttpStatusCode klasse.
