IWebProxy.Credentials 屬性

定義

命名空間:

System.Net

組件:

System.Net.Primitives.dll

認證，要送出至 Proxy 伺服器進行驗證。

public:
 property System::Net::ICredentials ^ Credentials { System::Net::ICredentials ^ get(); void set(System::Net::ICredentials ^ value); };

public System.Net.ICredentials? Credentials { get; set; }

member this.Credentials : System.Net.ICredentials with get, set

Public Property Credentials As ICredentials

屬性值

ICredentials

ICredentials 執行個體 (Instance)，包含要驗證 Proxy 伺服器要求所需的認證。

範例

下列範例會 Credentials 使用 屬性來設定將提交至 Proxy 伺服器的認證以進行驗證。

public ref class WebProxy_Interface: public IWebProxy
{
private:
   // The credentials to be used with the web proxy.
   ICredentials^ iCredentials;

   // Uri of the associated proxy server.
   Uri^ webProxyUri;

public:
   WebProxy_Interface( Uri^ proxyUri )
   {
      webProxyUri = proxyUri;
   }

   property ICredentials^ Credentials 
   {
      // Get and Set the Credentials property.
      virtual ICredentials^ get()
      {
         return iCredentials;

      // Always use the same proxy.
      return webProxyUri;
   }

   // Return whether the web proxy should be bypassed for the specified destination (hostUri).
   virtual bool IsBypassed( Uri^ hostUri )
   {

      return false;
   }
};

備註

屬性 Credentials 是 ICredentials 實例，其中包含要傳送至 Proxy 伺服器的授權認證，以回應 HTTP 407 (Proxy 授權) 狀態代碼。
