使用SSL從C＃應用程序調用WebService

Question

在我的C＃桌面應用程序中，我打電話使用PHP開發的Web服務。我可以擁有CA文件。我不知道如何通過SSL調用Web服務並驗證證書。我需要通過什麼服務器以及對服務器進行身份驗證時的響應情況？老實說，我不知道。

編輯： 從推介：http://weblogs.asp.net/jan/archive/2003/12/04/41154.aspx

//之前調用Web服務 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; 
    } 
} 

是檢查無誤上面的方法？如果不是爲什麼，可以解決什麼問題。我也得到這個警告：''System.Net.ServicePointManager.CertificatePolicy'已經過時：'CertificatePolicy已經過時了，請使用ServerCertificateValidationCallback。「

有了這個如何知道CheckValidationResult（）是否返回false？

任何幫助，高度讚賞。

感謝

Answer 1

您是否按照過時消息中的建議嘗試使用ServerCertificateValidationCallback？一旦這樣做了

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

，你可以用下面的替換現有

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

線：例如，你可以像下面的方法添加到您現有的MyPolicy類

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