摘要:The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel

Question:
the code is:
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://192.168.1.6/api/genreport.htm?id=413&periodoffset=0&repstart=1899-12-30-00-00-00&repend=1899-12-30-00-00-00&login=admin&password=123456&noclean=1");

            StreamReader sr = new StreamReader(request.GetResponse().GetResponseStream());  
            string result = sr.ReadToEnd();  
            File.WriteAllText("c:\\Resulst.xml", result);

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