Type.IsPointer プロパティ

Type がポインタかどうかを示す値を取得します。

名前空間: System
アセンブリ: mscorlib (mscorlib.dll 内)

public bool IsPointer { get; }
/** @property */
public final boolean get_IsPointer ()

public final function get IsPointer () : boolean

適用できません。

プロパティ値

Type がポインタである場合は true。それ以外の場合は false

現在の Type がジェネリック型、またはジェネリック型またはジェネリック メソッドの定義の型パラメータを表している場合、このプロパティは常に false を返します。

このプロパティは読み取り専用です。

IsPointer プロパティを使用する例を次に示します。
