NetworkCredential UseDefaultCredentials不起作用

我們編寫了一段代碼，可以調用具有域憑據的服務。現在域名已更改，並計劃使用默認的Windows帳戶NetworkCredential UseDefaultCredentials不起作用

所以我想通過配置爲asmx webservice重置網絡憑證。我創建了一個SoapExtentsion類，並試圖覆蓋那裏，即使它執行該行。但它從來沒有得到應用，並始終下面的現有代碼贏得

實際代碼

EmployeeService prxy = new EmployeeService(); 
prxy.Credentials = new System.Net.NetworkCredential("MyAccount", "pwd", "MyDomain"); 
//prxy.UseDefaultCredentials = true;// It works but we dont want code change 
prxy.GetEmployee(empId);

新代碼/配置變化只

規劃通過額外的DLL和配置的變化來注入。因此，在原來上面的代碼的代碼改變是不需要/現在禁止

public class WindowsDefCredSoapExtn : SoapExtension 
{ 
    public override object GetInitializer(Type serviceType) 
    { 
     return ""; 
    } 

    public override object GetInitializer(LogicalMethodInfo methodInfo, SoapExtensionAttribute attribute) 
    { 
     return ""; 
    } 

    public override void Initialize(object initializer) 
    { 
     //throw new NotImplementedException(); 
    } 

    public override void ProcessMessage(SoapMessage message) 
    { 

     if (message is SoapClientMessage) 
      { 
      if (message.Stage == SoapMessageStage.BeforeSerialize) 
       {        
       ((SoapClientMessage)message).Client.Credentials=null; 
       (((SoapClientMessage)message)).Client.UseDefaultCredentials = true; 

       } 
      }     

     } 

    } 
} 


<system.web> 
    <webServices> 
     <soapExtensionTypes> 
     <add type="MyAssembly.WindowsDefCredSoapExtn, MyAssembly" priority="1" group="Low"/> 
     </soapExtensionTypes> 
    </webServices> 
    </system.web>

任何一個知道如何動態地更改用於通過配置一個ASMX服務網絡憑據？

UPDATE：

雖然調試，我可以看到網絡憑據被重置。但不知怎的，它在調用請求時發送給服務器。

EmployeeService prxy = new EmployeeService(); 
prxy.Credentials = new System.Net.NetworkCredential("MyAccount", "pwd", "MyDomain"); 
//while debug, prxy.UseDefaultCredentials= false here 
//My soap extension gets executed and resets credentials. 
prxy.GetEmployee(empId); 
//while debug, prxy.UseDefaultCredentials= true here 
//while debug prxy.Credentials are null here.

輸出窗口：

參見最後一行AcquireCredentialsHandle通過authdata。即使重置我的服務擴展，也會使用prxy.Credentials = new System.Net.NetworkCredential("MyAccount", "pwd", "MyDomain")中設置的憑據。

更新2

我只是做了tesing代碼變化及以下的插座通信

AcquireDefaultCredential(package = NTLM, intent = Outbound)

差Vs

AcquireCredentialsHandle(package = NTLM, intent = Outbound, authdata = MyDomain\MyAccount)

如果我還記得，代碼配置總是戰勝的配置文件，在.NET框架的設計。首先加載Config，當代碼運行時，它將覆蓋設置。 – Nikki9696

通過配置注入我的代碼再次運行並重置值。但不知何故，它已經發送了憑據集。 – Billa

如果我理解你正確的話，我認爲你需要爲你的Acc添加密鑰ount，配置文件中appSettings下的用戶名和密碼。

<appSettings> 
    <add key="YourDomain" value="yourAccount"/> 
    <add key="UserName" value="yourAccount"/> 
    <add key="Password" value="yourAccount"/> 
</appSettings>

之後，在你的代碼，

EmployeeService prxy = new EmployeeService(); 
prxy.Credentials = new System.Net.NetworkCredential(System.Configuration.ConfigurationManager.AppSettings["UserName"].ToString(), System.Configuration.ConfigurationManager.AppSettings["Password"].ToString(), System.Configuration.ConfigurationManager.AppSettings["YourDomain"].ToString()); 
//while debug, prxy.UseDefaultCredentials= false here 
//My soap extension gets executed and resets credentials. 
prxy.GetEmployee(empId);

這是我目前的想要擺脫這個...真正的問題是如何通過配置擺脫這一點。 – Billa

它不可能擺脫這一點。 –
