注釈

すべてのメンバーには、特定の種類のメンバーに対して定義されている一連の属性があります。All members have a set of attributes, which are defined in relation to the specific type of member.

を取得MethodAttributesするには、最初に型を取得します。To get the MethodAttributes, first get the type. 型からメソッドを取得します。From the type, get the method. メソッドから、 MethodAttributesを取得します。From the method, get the MethodAttributes.

注意 (実装者)

private public virtual finalプロパティを使用して、メソッドが、、、などであるかどうかを判断します。 AttributesUse the Attributes property to determine whether a method is public, private, final, virtual, and so on.
