HttpRequest.LogonUserIdentity 屬性

定義

命名空間:

System.Web

組件:

System.Web.dll

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

WindowsIdentity

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

例外狀況

InvalidOperationException

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。

    *  in IIS 6.x NETWORK SERVICE), and give it write permissions
    *  to the folder.*/

    private const string INFO_DIR = @"c:\temp\";

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 LogonUserIdentity 的 WindowsIdentity 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。
