XmlIncludeAttribute.Type プロパティ

含めるオブジェクトの型を取得または設定します。

Public Property Type As Type
[C#]
public Type Type {get; set;}
[C++]
public: __property Type* get_Type();public: __property void set_Type(Type*);
[JScript]
public function get Type() : Type;public function set Type(Type);

プロパティ値

含めるオブジェクトの Type 。

使用例

[Visual Basic, C#, C++] Employee オブジェクトの配列を返すフィールド Employees を含むクラス Group を定義する例を次に示します。この例では、Employee クラスから Manager クラスを派生させ、 XmlIncludeAttribute を Employee クラスに適用します。Group オブジェクトが作成されると、Manager オブジェクトを Employee 配列に挿入します。最後に、Group オブジェクトをシリアル化します。
