MethodBase.IsFamilyOrAssembly プロパティ

定義

このメソッドまたはコンストラクターを参照可能な範囲が FamORAssem 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任意の場所にある派生クラスと、同じアセンブリ内のクラスから呼び出すことができるものであることです。Gets a value indicating whether the potential visibility of this method or constructor is described by FamORAssem; that is, the method or constructor can be called by derived classes wherever they are, and by classes in the same assembly.

public:
 property bool IsFamilyOrAssembly { bool get(); };
public bool IsFamilyOrAssembly { get; }
member this.IsFamilyOrAssembly : bool
Public ReadOnly Property IsFamilyOrAssembly 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 FamORAssem 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 FamORAssem; otherwise, false.

注釈

型のメンバーが MethodAttributes.FamORAssem 可視性を持つ場合は、派生クラス内の任意のメンバー、または同じアセンブリ内の任意のメンバーから呼び出すことができますが、他の型からは呼び出せません。If a type member has MethodAttributes.FamORAssem visibility, it can be called from any member in a derived class or any member in the same assembly, but not from any other type.

メソッドの実際の可視性は、その型の可視性によって制限されます。The actual visibility of a method is limited by the visibility of its type. プロパティは、 IsFamilyOrAssembly メソッドの場合もあり true ますが、入れ子になったプライベート型のメソッドである場合、メソッドは、それを含んでいる型の外部では参照できません。The IsFamilyOrAssembly property might be true for a method, but if it is a method of a private nested type then the method is not visible outside the containing type.

MethodAttributes.FamORAssem可視性修飾子が protected internal C# (Visual Basic では C++) にある場合、メソッドまたはコンストラクターの可視性はによって正確に記述され Protected Friend protected public ます。The visibility of a method or constructor is exactly described by MethodAttributes.FamORAssem if the visibility modifier is protected internal in C# (Protected Friend in Visual Basic, protected public in C++).
