Question

I am trying to get Web Page Contents in Code with C# but its giving me error. Please help me to fix it.

  string url = "http://www.abesoft.org/query.asp
                searchtype=ANY&
                query_param=USDOT&original_query_param=NAME&
                query_string=2134430&original_query_string=NATIONAL GRASS LLC";

 WebRequest request = WebRequest.Create(url);
 WebResponse response = request.GetResponse();
 Stream data = response.GetResponseStream();
 string html = String.Empty;
 using (StreamReader sr = new StreamReader(data))
 {
      html = sr.ReadToEnd();
 }

Error- "The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel."

You can probably use:

 ServicePointManager.CertificatePolicy = delegate { return true; };

To ignore the certificate errors. Source is this article:

Basically you are just trying to ignore the bad certificate on that site.
