Příklady

Následující příklad používá ServiceController třídu k zobrazení služeb ovladače zařízení v místním počítači.

Poznámky

GetDevices vrátí pouze služby ovladače zařízení z místního počítače. Pokud chcete načíst služby jiných ovladačů než ovladače zařízení nebo služby, které nejsou ovladači, zavolejte metodu GetServices . Tyto dvě metody společně poskytují přístup ke všem službám v počítači.
