Process.Exited Process.Exited Process.Exited Process.Exited Event

定義

プロセスが終了したときに発生します。Occurs when a process exits.

public:
 event EventHandler ^ Exited;
public event EventHandler Exited;
member this.Exited : EventHandler 
Public Custom Event Exited As EventHandler 

次のコード例では、ファイルを出力するプロセスを作成します。The following code example creates a process that prints a file. 生成、Exitedため、プロセスが終了するときにイベントをEnableRaisingEventsプロセスの作成時にプロパティが設定されました。It raises the Exited event when the process exits because the EnableRaisingEvents property was set when the process was created. Exitedイベント ハンドラーは、プロセス情報を表示します。The Exited event handler displays process information.

注釈

Exitedイベントは、関連付けられたプロセスが終了していることを示します。The Exited event indicates that the associated process exited. この状況の発生を意味するか、プロセス終了 (中止) または正常に終了します。This occurrence means either that the process terminated (aborted) or successfully closed. 場合にのみ、このイベントが発生する可能性がの値、EnableRaisingEventsプロパティはtrueします。This event can occur only if the value of the EnableRaisingEvents property is true.

関連付けられたプロセスが終了したときに通知する 2 つの方法がある: 同期的および非同期的にします。There are two ways of being notified when the associated process exits: synchronously and asynchronously. 同期の通知呼び出し元の意味、WaitForExitプロセスを終了するまで、現在のスレッドをブロックするメソッド。Synchronous notification means calling the WaitForExit method to block the current thread until the process exits. 非同期通知を使用して、Exitedイベントで、呼び出し元スレッドがその間に実行を続行することができます。Asynchronous notification uses the Exited event, which allows the calling thread to continue execution in the meantime. 後者の場合、EnableRaisingEventsに設定する必要がありますtrueExited イベントを受信する呼び出し元のアプリケーション。In the latter case, EnableRaisingEvents must be set to true for the calling application to receive the Exited event.

オペレーティング システムをシャット ダウン、プロセス、Exited イベントのハンドラーを登録している他のすべてのプロセスを通知します。When the operating system shuts down a process, it notifies all other processes that have registered handlers for the Exited event. この時点でだけが終了したプロセスのハンドルを使用してなど一部のプロパティにアクセスするExitTimeHasExitedそのハンドルを完全に解放するまで、オペレーティング システムが維持されます。At this time, the handle of the process that just exited can be used to access some properties such as ExitTime and HasExited that the operating system maintains until it releases that handle completely.

注意

呼び出すことはできません、終了プロセスを識別するハンドルがある場合でもStart再接続するには、同じプロセスです。Even if you have a handle to an exited process, you cannot call Start again to reconnect to the same process. 呼び出すStart自動的に関連付けられたプロセスを解放し、同じファイルが完全に新しいプロセスに接続Handleします。Calling Start automatically releases the associated process and connects to a process with the same file but an entirely new Handle.
