WindowClosedEventArgs.GetRuntimeId メソッド

定義

名前空間:

System.Windows.Automation

アセンブリ:

UIAutomationTypes.dll

このイベントに関連付けられているUI オートメーションランタイム識別子 (ID) を取得します。

public:
 cli::array <int> ^ GetRuntimeId();

public int[] GetRuntimeId ();

member this.GetRuntimeId : unit -> int[]

Public Function GetRuntimeId () As Integer()

戻り値

Int32[]

イベントが発生したウィンドウのUI オートメーションランタイム ID。

例

次の例では、ウィンドウを閉じたイベントのハンドラーは、閉じたウィンドウのランタイム ID が開いているウィンドウの ID の一覧にあるかどうかを確認します。 ランタイム ID が存在する場合は、一覧から削除されます。

注釈

アプリケーションがウィンドウ閉じイベントを受信すると、sender対応する Microsoft UI オートメーション 要素が無効になったため、イベント ハンドラーのパラメーターを使用して閉じたウィンドウに関する情報を取得することはできません。 ウィンドウを既知の識別子と一致させるために使用 GetRuntimeId します。
