错误 3 “CheckValidationResult”的重载均与委托“System.Net.Security.RemoteCertificateValidationCallback”不匹配
这个是什么意思呢??ServicePointManager.ServerCertificateValidationCallback = new System.Net.Security.RemoteCertificateValidationCallback(CheckValidationResult);

Answer 5

using System.Security.Cryptography.X509Certificates;
我用2003測試正常
