MethodBase.Attributes プロパティ
アセンブリ: mscorlib (mscorlib.dll 内)

Public MustOverride ReadOnly Property Attributes As MethodAttributes
public abstract MethodAttributes Attributes { get; }
MethodAttributes 値の 1 つ。

すべてのメンバが属性のセットを持っています。属性は、メンバの特定の型との関係で定義されます。
MethodAttributes を取得するには、最初に型を取得します。型からメソッドを取得します。メソッドから MethodAttributes を取得します。
実装時の注意 Attributes プロパティを使用して、メソッドが public、private、final、virtual、その他のいずれであるかを確認します。
ユーザー定義のメソッド Mymethod の属性を表示するコードの例を次に示します。
