Type.IsSpecialName プロパティ
Type の名前が特別な処理を必要とするかどうかを示す値を取得します。
Public ReadOnly Property IsSpecialName As Boolean
[C#]
public bool IsSpecialName {get;}
[C++]
public: __property bool get_IsSpecialName();
[JScript]
public function get IsSpecialName() : Boolean;
プロパティ値
Type の名前が特別な処理を必要とする場合は true 。それ以外の場合は false 。
解説
アンダースコア (_)、プロパティ アクセサ、メソッドをオーバーロードする演算子などで始まるか、それらを含む名前の型は、一部のコンパイラでは特別な処理が必要になります。
使用例
IsSpecialName を使用して、内部メンバまたはプライベート メンバをリストから抽出するコード例を次に示します。
