MethodBase.IsFamilyAndAssembly プロパティ

定義

このメソッドまたはコンストラクターへの参照範囲が FamANDAssem によって示されるかどうかを表す値を取得します。ここで判定されるのは、メソッドまたはコンストラクターは派生クラスから呼び出すことができるが、それらが同じアセンブリ内にある場合に限るものであることです。Gets a value indicating whether the visibility of this method or constructor is described by FamANDAssem; that is, the method or constructor can be called by derived classes, but only if they are in the same assembly.

public:
 property bool IsFamilyAndAssembly { bool get(); };
public bool IsFamilyAndAssembly { get; }
member this.IsFamilyAndAssembly : bool
Public ReadOnly Property IsFamilyAndAssembly As Boolean

プロパティ値

Boolean

このメソッドまたはコンストラクターへのアクセスが FamANDAssem によって正しく示される場合は true。それ以外の場合は falsetrue if access to this method or constructor is exactly described by FamANDAssem; otherwise, false.

実装

次のコード例では、さまざまなレベルの可視性を持つメソッドを定義し、、、、およびの各プロパティの値を表示し IsAssembly IsFamily IsFamilyOrAssembly IsFamilyAndAssembly ます。The following code example defines methods with varying levels of visibility, and displays the values of their IsAssembly, IsFamily, IsFamilyOrAssembly, and IsFamilyAndAssembly properties.

        "", "IsPublic", "IsFamily", "IsFamilyAndAssembly");

    for each (MethodBase^ m in Example::typeid->GetMethods(
        BindingFlags::Instance | BindingFlags::NonPublic | BindingFlags::Public))
