MethodBase.IsAssembly Propriété

Définition

Obtient une valeur indiquant si la visibilité potentielle de cette méthode ou de ce constructeur est décrite par Assembly, c'est-à-dire si la méthode ou le constructeur est visible au maximum par d'autres types du même assembly, et n'est pas visible par des types dérivés à l'extérieur de l'assembly.Gets a value indicating whether the potential visibility of this method or constructor is described by Assembly; that is, the method or constructor is visible at most to other types in the same assembly, and is not visible to derived types outside the assembly.

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

Valeur de propriété

true si la visibilité de cette méthode ou de ce constructeur est décrite exactement par Assembly ; sinon, false.true if the visibility of this method or constructor is exactly described by Assembly; otherwise, false.

Exemples

L’exemple de code suivant définit des méthodes avec différents niveaux de visibilité et affiche les valeurs de IsAssemblyleurs IsFamilypropriétés IsFamilyOrAssembly,, IsFamilyAndAssembly et.The following code example defines methods with varying levels of visibility, and displays the values of their IsAssembly, IsFamily, IsFamilyOrAssembly, and IsFamilyAndAssembly properties.

Notes

Les Visual Basic et C# les langages ne peuvent MethodAttributes.FamANDAssem pas définir de méthodes avec visibilité ; ce niveau C++ d’accès apparaît uniquement dans l’exemple.The Visual Basic and C# languages cannot define methods with MethodAttributes.FamANDAssem visibility; that access level appears only in the C++ example.

Remarques

La visibilité réelle d’une méthode est limitée par la visibilité de son type.The actual visibility of a method is limited by the visibility of its type. La IsAssembly propriété peut être true pour une méthode, mais s’il s’agit d’une méthode d’un type imbriqué privé, la méthode n’est pas visible à l’extérieur du type conteneur.The IsAssembly 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.

La visibilité d’une méthode ou d’un constructeur est décrite MethodAttributes.Assembly exactement par si le seul modificateur internal deFriend visibilité est (en Visual Basic).The visibility of a method or constructor is exactly described by MethodAttributes.Assembly if the only visibility modifier is internal (Friend in Visual Basic). Cette propriété est false destinée aux méthodes qui protected internal se C# trouventProtected Friend dans (dans protected public Visual Basic C++, dans); IsFamilyOrAssembly utilisez la propriété pour identifier de telles méthodes.This property is false for methods that are protected internal in C# (Protected Friend in Visual Basic, protected public in C++); use the IsFamilyOrAssembly property to identify such methods.
