我使用HttpWebRequest访问其他网站时,出现"请求被中止：无法建立 SSL / TLS安全通道"错误,于是goog和百度了一番,提供的答案基本是:ServicePointManager.ServerCertificateValidationCallback写委托

 
          public 
          ResponseModel GetHtml( 
          string 
          url) 
         
          { 
         
          ServicePointManager.ServerCertificateValidationCallback = ValidateServerCertificate; 
         
          HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url); 
         
          } 
         
          private 
          bool 
          ValidateServerCertificate( 
          object 
          sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors) 
         
          { 
         
          return 
          true 
          ; 
         
          }

但这种方法对我无效,该出现的错误还是继续出现.

最终解决办法是,在访问url前执行语句 ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3;即可

 
          public 
          ResponseModel GetHtml( 
          string 
          url)  
         
          { 
         
          ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3;  
         
          　　　HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);  
         
          }
