MethodBase.IsFamilyAndAssembly Propriété

Définition

Espace de noms:

System.Reflection

Assembly:

System.Runtime.dll

Source:

MethodBase.cs

Obtient une valeur indiquant si la visibilité de cette méthode ou de ce constructeur est décrite par FamANDAssem, c'est-à-dire si la méthode ou le constructeur peut être appelé par des classes dérivées, mais uniquement si elles se trouvent dans le même assembly.

public:
 property bool IsFamilyAndAssembly { bool get(); };

public bool IsFamilyAndAssembly { get; }

member this.IsFamilyAndAssembly : bool

Public ReadOnly Property IsFamilyAndAssembly As Boolean

Valeur de propriété

Boolean

true si l'accès à cette méthode ou à ce constructeur est décrit exactement par FamANDAssem ; sinon, false.

Exemples

L’exemple de code suivant définit des méthodes avec différents niveaux de visibilité et affiche les valeurs de leurs IsAssemblypropriétés , IsFamily, IsFamilyOrAssemblyet IsFamilyAndAssembly .

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

Remarques

La visibilité d’une méthode ou d’un constructeur est décrite exactement par MethodAttributes.FamANDAssem si le modificateur de visibilité est private protected en C#, Private Protected en Visual Basic ou protected private en C++.
