備註

使用此方法建立一個新 Process 元件，並將其與本地電腦上的程序資源關聯。程序資源必須已存在於電腦上，因為它 GetProcessById(Int32) 不會產生系統資源，而是將資源與應用程式產生 Process 的元件關聯起來。 Id程序只能為目前在電腦上執行的程序檢索。程序終止後，如果你傳給它一個過期的識別碼， GetProcessById(Int32) 它會拋出例外。

在任何特定電腦上，程序的識別碼是唯一的。 GetProcessById(Int32) 最多只能回退一個流程。如果你想讓所有程序在特定應用程式上運行，請使用 GetProcessesByName(String)。如果執行指定應用程式的電腦上存在多個程序，則 GetProcessesByName(String) 會回傳包含所有相關程序的陣列。你可以依序查詢每個程序的識別碼。程序識別碼可在 Windows 工作管理員的 Processes 面板中查看。欄位 PID 顯示分配給程序的程序識別碼。

processId參數為 Int32（32 位元有號整數），但底層 Windows API 對類似 API 使用 DWORD（未簽名 32 位元整數）。這是出於歷史考量。
