備註

使用這個方法來建立新 Process 元件的數位，並將其與本機計算機上的所有進程資源產生關聯。 進程資源必須已存在於本機計算機上，因為 GetProcesses 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。 因為操作系統本身正在執行背景進程，所以這個數位永遠不會是空的。

如果您不想擷取電腦上執行的所有進程，您可以使用 或 GetProcessesByName 方法來限制其數目GetProcessById。 GetProcessById 會 Process 建立元件，該元件與您傳遞至 方法的進程標識符，與系統上識別的進程相關聯。 GetProcessesByName 會建立元件數位， Process 其相關聯的進程資源會共用您傳遞至 方法的可執行檔。

注意

您可以在服務主機進程的相同實例內載入多個 Windows 服務 (svchost.exe) 。 GetProcesses 不會識別這些個別服務;如需此專案，請參閱 GetServices。
