You can just catch the WebException, and then, check the ProtocolError and status code.

}
catch(WebException e) {
    if(e.Status == WebExceptionStatus.ProtocolError) {
        Console.WriteLine("Status Code : {0}", ((HttpWebResponse)e.Response).StatusCode);
        Console.WriteLine("Status Description : {0}", ((HttpWebResponse)e.Response).StatusDescription);
    }
}
catch(Exception e)
{
//
}

Nice answer. Keep in mind you can still add another `catch(Exception e)` after this catch if you want to do other things with other exceptions. – Joelius Jun 09 '19 at 07:38
