https网站访谒第三方https网站时候报错：

The request was aborted:Could not create SSL/TLS secure channel.

解决步伐：

if(Url.StartsWith("https",StringComparison.OrdinalIgnoreCase))//https请求 { ServicePointManager.Expect100Continue = true; //如果是4.5以上版本可以直接使用 //ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls // | SecurityProtocolType.Tls11 // | SecurityProtocolType.Tls // | SecurityProtocolType.Ssl3; ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls | (SecurityProtocolType)768 | (SecurityProtocolType)3072 | SecurityProtocolType.Ssl3; ServicePointManager.ServerCertificateValidationCallback = new System.Net.Security.RemoteCertificateValidationCallback(CheckValidationResult); request = WebRequest.Create(Url_Temp) as HttpWebRequest; request.ProtocolVersion = HttpVersion.Version10; } else { request = WebRequest.Create(Url_Temp) as HttpWebRequest; }

回调函数：

private static bool CheckValidationResult(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors) { //为了通过证书验证，，总是返回true return true; }
