備註

使用這個方法來建立新的 Process 元件,並將它與本機計算機上的進程資源產生關聯。 進程資源必須已經存在計算機上,因為 GetProcessById(Int32) 不會建立系統資源,而是將資源與應用程式產生的 Process 元件產生關聯。 只能針對目前在計算機上執行的進程擷取進程 Id 。 進程終止之後,如果您傳遞過期的標識符, GetProcessById(Int32) 則會擲回例外狀況。

在任何特定的計算機上,進程的標識碼是唯一的。 GetProcessById(Int32) 最多會傳回一個進程。 如果您要取得執行特定應用程式的所有行程,請使用 GetProcessesByName(String)。 如果執行指定應用程式的計算機上存在多個進程,則 GetProcessesByName(String) 傳回包含所有相關聯進程的陣列。 您可以依序查詢每個處理程式的識別碼。 進程標識元可以在 Windows 任務管理員的面板中檢視 Processes 。 數據 PID 行會顯示指派給進程的進程標識碼。

參數 processIdInt32 (32 位帶正負號的整數) ,雖然基礎 Windows API 會針對類似的 API 使用 DWORD 不帶正負號的 32 位整數 () 。 這是基於歷史原因。
