  3. Redirection message (300 - 399)
  4. Client error response (400 - 499)
  5. Server error response (500 - 599)

How to Create a Web Request?

To create a web request you need to use the HttpWebRequest class that enables you to request a server using Http by using WebRequest.Create() method.Remember to add System.Net namespace so you can access theses classes.

using System.Net;

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(“https://debug.to”);

Then you need to get the response for that site request using the class HttpWebResponse and the method GetResponse()

HttpWebResponse response = (HttpWebResponse)request.GetResponse();

Now you can get the status code for that response using the HttpStatusCode class 

HttpStatusCode statusCode = response.StatusCode;
