名前空間: System.EnterpriseServices
アセンブリ: System.EnterpriseServices (system.enterpriseservices.dll 内)
構文

Visual Basic (宣言)

Public Property Enabled As
 Boolean

Visual Basic (使用法)

Dim instance As ObjectPoolingAttribute
Dim value As Boolean

value = instance.Enabled

instance.Enabled = value

public bool Enabled { get;
 set; }

C++

public:
property bool Enabled {
    bool get ();
    void set (bool value);
}

/** @property */
public boolean get_Enabled ()

/** @property */
public void set_Enabled (boolean value)

JScript

public function get Enabled
 () : boolean

public function set Enabled
 (value : boolean)

プロパティ値
オブジェクトプーリングが有効な場合は true。それ以外の場合は false。既定値は true です。

        attribute.Enabled = true;

            attribute.Enabled);
    }
}

C++

[ObjectPooling(false)]

        Console::WriteLine("ObjectPoolingAttribute.Enabled: {0}",
            attribute->Enabled);
    }
};

/** @attribute ObjectPooling(false)
 */
