AppDomainSetup.AppDomainInitializer 屬性
定義
重要
部分資訊涉及發行前產品，在發行之前可能會有大幅修改。 Microsoft 對此處提供的資訊，不做任何明確或隱含的瑕疵擔保。
取得或設定 AppDomainInitializer 委派，其表示當初始化應用程式定義域時所叫用的回呼方法。
public:
property AppDomainInitializer ^ AppDomainInitializer { AppDomainInitializer ^ get(); void set(AppDomainInitializer ^ value); };public AppDomainInitializer AppDomainInitializer { get; set; }member this.AppDomainInitializer : AppDomainInitializer with get, setPublic Property AppDomainInitializer As AppDomainInitializer屬性值
表示回呼方法的委派，在應用程式定義域初始化時會叫用此方法。
範例
下列範例會使用 AppDomainSetup 預設應用程式域中的物件和辨識項，建立名為 的 ChildDomain 子應用程式域。 屬性 AppDomainInitializer 會設定為回呼方法，這個方法 AppDomainInit 會在初始化子域時叫用。 回呼方法的引數會放在指派給 AppDomainInitializerArguments 屬性的字串陣列中。 建立子域時，回呼方法只會列印字串。

備註
若要將資訊傳遞至回呼方法，請將字串陣列指派給 AppDomainInitializerArguments 屬性。 每次初始化 時 AppDomain ，陣列都會傳遞至回呼方法。
回呼方法會在新建立的應用程式域內容中執行。
