HttpRequest.LogonUserIdentity 屬性

定義

取得目前使用者的 WindowsIdentity 類型。

public:
 property System::Security::Principal::WindowsIdentity ^ LogonUserIdentity { System::Security::Principal::WindowsIdentity ^ get(); };
public System.Security.Principal.WindowsIdentity LogonUserIdentity { get; }
member this.LogonUserIdentity : System.Security.Principal.WindowsIdentity
Public ReadOnly Property LogonUserIdentity As WindowsIdentity

屬性值

目前 Microsoft Internet Information Services (IIS) 驗證設定的 WindowsIdentity 物件。

例外狀況

Web 應用程式是在 IIS 7 整合模式中執行,而且尚未引發 PostAuthenticateRequest 事件。

範例

下列程式碼範例示範如何擷取 LogonUserIdentity 目前使用者的 屬性,並寫出文字檔中每個專案的值。 將此程式碼放在表單 ACTION 屬性所參考的 ASP.NET 網頁上。

    *  to the folder.*/

備註

屬性 LogonUserIdentity 會公開目前連線使用者之 物件的屬性和方法 WindowsIdentity ,以Microsoft Internet Information Services (IIS) 。 由 追蹤 IIS 要求權杖公開 LogonUserIdentityWindowsIdentity 類別實例,並提供在 ASP.NET 內處理之目前 HTTP 要求的簡單存取權。 系統會自動建立 類別的 WindowsIdentity 實例,因此不需要建構它才能存取其方法和屬性。
