取得或設定 COM 驗證等級,以使用於這個連接中的作業。
public:
property System::Management::AuthenticationLevel Authentication { System::Management::AuthenticationLevel get(); void set(System::Management::AuthenticationLevel value); };
public System.Management.AuthenticationLevel Authentication { get; set; }
member this.Authentication : System.Management.AuthenticationLevel with get, set
Public Property Authentication As AuthenticationLevel
屬性值
傳回 AuthenticationLevel 列舉值,表示連接到本機或遠端電腦所使用的 COM 驗證等級。
範例
下列範例會連線到遠端電腦,並顯示遠端電腦上的作業系統相關信息。 會建立 , ConnectionOptions 以使用所需的連線選項連線到遠端電腦。

備註
在 Windows 2000 和更新版本上,WMI 服務會要求 Connect 層級驗證,而在 Windows XP 和更高版本上,則會要求封包層級驗證。 如果用戶端需要特定的驗證設定,這個屬性可用來控制此特定連線上的驗證層級。 例如,如果用戶端需要加密所有通訊,則可以將 屬性設定 AuthenticationLevel.PacketPrivacy 為 。
屬性值
要用於此連線中作業的 COM 驗證層級。 預設值為 AuthenticationLevel.Unchanged,表示用戶端會根據標準 DCOM 交涉程式,使用伺服器所要求的驗證層級。
