使用SSL从C＃应用程序调用WebService

Question

在我的C＃桌面应用程序中，我打电话使用PHP开发的Web服务。我可以拥有CA文件。我不知道如何通过SSL调用Web服务并验证证书。我需要通过什么服务器以及对服务器进行身份验证时的响应情况？老实说，我不知道。

编辑： 从推介：http://weblogs.asp.net/jan/archive/2003/12/04/41154.aspx

//之前调用Web服务 System.Net.ServicePointManager.CertificatePolicy =新MyPolicy（）;

public class MyPolicy : ICertificatePolicy 
{ 
    X509Certificate clientCert = null; 

    public MyPolicy() { 
     clientCert = X509Certificate.CreateFromSignedFile(HTTPUtility.CERT_FILE); 
    } 

    public bool CheckValidationResult(ServicePoint srvPoint, X509Certificate certificate, WebRequest request, int certificateProblem) 
    { 
     Console.WriteLine("********* Into CheckValidationResult : " + certificate.ToString()); 

     Console.WriteLine("####### Client Certificate : " + clientCert.ToString() + "\n" + "Subject = " + clientCert.Subject); 
     Console.WriteLine("Issuer : " + clientCert.Issuer + "\n Seral No : " + clientCert.GetSerialNumberString()); 
     Console.WriteLine("Not Before : " + clientCert.GetEffectiveDateString() +" \n Not After : " + clientCert.GetExpirationDateString()); 
     Console.WriteLine("Thumb Print : " + clientCert.GetPublicKeyString()); 
     Console.WriteLine("######## EQuals SERVER CERT : " + clientCert.Equals(certificate)); 

     // Force to return true 
     return true; 
    } 
} 

是检查无误上面的方法？如果不是为什么，可以解决什么问题。我也得到这个警告：''System.Net.ServicePointManager.CertificatePolicy'已经过时：'CertificatePolicy已经过时了，请使用ServerCertificateValidationCallback。“

有了这个如何知道CheckValidationResult（）是否返回false？

任何帮助，高度赞赏。

感谢

Answer 1

您是否按照过时消息中的建议尝试使用ServerCertificateValidationCallback？一旦这样做了

public bool ValidateServerCertificate(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors) 
{ 
    Console.WriteLine(sslPolicyErrors); // Or whatever you want to do... 
    return true; 
} 

，你可以用下面的替换现有

System.Net.ServicePointManager.CertificatePolicy = new MyPolicy(); 

线：例如，你可以像下面的方法添加到您现有的MyPolicy类

MyPolicy policy = new MyPolicy(); 
System.Net.ServicePointManager.ServerCertificateValidationCallback = policy.ValidateServerCertificate;
