備註

你可以用這個 ServiceController 類別連接並控制現有服務的行為。 當你建立該類別的實例 ServiceController 時，你會設定它的屬性，使其與特定的 Windows 服務互動。 接著你可以用這個類別來啟動、停止或以其他方式操作服務。

你很可能會以行政身份使用這個 ServiceController 元件。 例如，你可以建立一個 Windows 或網頁應用程式，透過實 ServiceController 例向服務發送自訂指令。 這很有用，因為 Microsoft 管理控制台的服務控制管理器（SCM）不支援自訂指令。

在建立一個 ServiceController實例 後，必須設定兩個屬性來識別它所互動的服務：電腦名稱和你想控制的服務名稱。

通常，服務作者會撰寫程式碼，來自訂與特定指令相關的動作。 例如，一個服務可以包含回應 ServiceBase.OnPause 指令的程式碼。 在這種情況下，該任務的自訂處理 Pause 會在系統暫停服務之前執行。

服務能處理的指令集合取決於其屬性;例如，你可以將某項服務的屬性設定 CanStop 為 false。 此設定會使 Stop 該指令在該服務中無法使用;它阻止你透過停用必要的按鈕來停止服務。 如果你嘗試從程式碼停止服務，系統會跳出錯誤並顯示「Failed to stop servicename.」的錯誤訊息。
