C#: Check if Web Page is Up, Http Status Code

If you need to programmatically check to see if a web page or web service is active before you redirect a user or make a call you can use the HttpWebRequest object to make a call to a URL and get back the HttpWebResponse. Through the HttpWebResponse you can then check the HttpStatusCode to see if it is OK or an # of other statuses base on what you are looking for.

        private void CheckUrl()


            const string SERVICE_URL =



            WebRequest testRequest = WebRequest.Create(SERVICE_URL);

            testRequest.Proxy = null;

            HttpWebResponse testResponse = (HttpWebResponse)testRequest.GetResponse();

            if (testResponse.StatusCode != HttpStatusCode.OK)


                throw new Exception(

                    "Unable to hit Google.");,
