範例

下列範例會連線到遠端電腦，並顯示遠端電腦上作業系統的相關信息。 會建立 ， ConnectionOptions 以使用所需的連線選項連線到遠端電腦。

備註

當提供者是受信任的應用程式或服務時，此 ImpersonationLevel.Impersonate 設定會很有利。 它不需要提供者執行要求的作業的用戶端身分識別和存取檢查。 不過，如果基於某些原因，提供者無法信任，允許它模擬用戶端可能會構成安全性威脅。 在這種情況下，我們建議用戶端將此屬性設定為較低的值，例如 ImpersonationLevel.Identify。 請注意，這可能會導致提供者無法執行要求的作業，因為沒有足夠的許可權或無法執行存取檢查。

屬性值

要用於此連線中作業的 COM 模擬層級。 預設值為 ImpersonationLevel.Impersonate，表示 WMI 提供者可以在此連接中執行要求的作業時模擬用戶端。
