Przykłady

Aby skorzystać z poniższego przykładu, należy najpierw uruchomić co najmniej jedno wystąpienie Notatnika na komputerze zdalnym.To use the following example you must first start at least one instance of Notepad on a remote computer. Przykład żąda nazwy komputera zdalnego, na którym jest uruchomiony Notatnik, a następnie wyświetla odpowiednie ProcessName Id MachineName właściwości dla każdego wystąpienia.The example requests the name of the remote computer on which Notepad is running, and then displays the respective ProcessName, Id, and MachineName properties for each instance.

Uwagi

Można wyświetlić dane statystyczne i informacje o procesie procesów uruchomionych na komputerach zdalnych, ale nie można wywoływać Start , CloseMainWindow lub Kill na komputerach zdalnych.You can view statistical data and process information for processes running on remote computers but you cannot call Start, CloseMainWindow, or Kill on remote computers.

Uwaga

Gdy skojarzony proces jest wykonywany na komputerze lokalnym, ta właściwość zwraca kropkę (".") dla nazwy maszyny.When the associated process is executing on the local machine, this property returns a period (".") for the machine name. Należy użyć właściwości, Environment.MachineName Aby uzyskać poprawną nazwę komputera.You should use the Environment.MachineName property to get the correct machine name.
