ApplicationContext クラスを使用すると、メッセージ ループを終了させる条件を再定義できます。既定では、ApplicationContext がアプリケーションのメイン Form の Closed イベントを待機してから、スレッドのメッセージ ループを終了します。
2 つのフォームを表示し、両方のフォームが閉じられたときにアプリケーションを終了するコード例を、次に示します。アプリケーションの開始時と終了時に、各フォームの位置が記憶されます。この例では、ApplicationContext を Application.Run(context) メソッドと共に使用して、アプリケーションの起動時に複数のフォームを表示する方法を示します。
MyApplicationContext クラスは、ApplicationContext の継承クラスで、各フォームがいつ閉じられたのかを追跡し、両方のフォームが閉じられたときに現在のスレッドを終了します。このクラスは、ユーザーの代わりに各フォームの位置を格納します。フォームの位置データは、Appdata.txt という名前のファイルに格納されます。このファイルは、UserAppDataPath で指定された場所に作成されます。
Main メソッドは、Application.Run(context) を呼び出すことにより、ApplicationContext を指定してアプリケーションを起動します。
