HttpWebRequest向https网址post的时候总是无法连接到远程服务器，怎么办啊

Question

用同一个方法访问http的完全正常。。。
我也加了设置：

 if (url.StartsWith("https", StringComparison.OrdinalIgnoreCase))   //https请求
            {
                ServicePointManager.ServerCertificateValidationCallback =
                    new RemoteCertificateValidationCallback(CheckValidationResult);
                myRequest = WebRequest.Create(url) as HttpWebRequest;
                myRequest.ProtocolVersion = HttpVersion.Version11;
            }
                        ...
                        private static bool CheckValidationResult(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors errors)
        {
            return true; //总是接受  
        }  

每次在Stream newStream = myRequest.GetRequestStream();这句的时候就异常，实在找不到原因了！

你用普通的html表单post过去看能正常执行没有，如果不行就是接口的问题，和httpwebrequest无关了
