public:
 property AppDomainInitializer ^ AppDomainInitializer { AppDomainInitializer ^ get(); void set(AppDomainInitializer ^ value); };

Public Property AppDomainInitializer As AppDomainInitializer

プロパティ値

アプリケーション ドメインの初期化時に呼び出されるコールバック メソッドを表すデリゲート。A delegate that represents a callback method that is invoked when the application domain is initialized.

次の例では、という名前の子アプリケーション ドメインを作成するChildDomainを使用して、AppDomainSetupオブジェクトと既定のアプリケーション ドメインからの証拠。The following example creates a child application domain named ChildDomain, using an AppDomainSetup object and evidence from the default application domain. AppDomainInitializerコールバック メソッドに設定されてAppDomainInit、子ドメインの初期化時に呼び出されます。The AppDomainInitializer property is set to the callback method AppDomainInit, which is invoked when the child domain is initialized. コールバック メソッドの引数に割り当てられている、文字列の配列に配置されます、AppDomainInitializerArgumentsプロパティ。The arguments for the callback method are placed in an array of strings, which is assigned to the AppDomainInitializerArguments property. 子ドメインが作成されると、コールバック メソッドの文字列が出力されます。When the child domain is created, the callback method simply prints the strings.

注釈

情報をコールバック メソッドに渡すために文字列の配列を割り当てる、AppDomainInitializerArgumentsプロパティ。To pass information to the callback method, assign an array of strings to the AppDomainInitializerArguments property. 配列が毎回、コールバック メソッドに渡される、AppDomain初期化されます。The array is passed to the callback method each time an AppDomain is initialized.

コールバック メソッドは、新しく作成されたアプリケーション ドメインのコンテキストで実行されます。The callback method is executed in the context of the newly created application domain.
