MethodBase.IsAssembly MethodBase.IsAssembly MethodBase.IsAssembly MethodBase.IsAssembly Property

Definition

Ruft einen Wert ab, der angibt, ob die potenzielle Sichtbarkeit dieser Methode bzw. dieses Konstruktors von Assembly beschrieben wird, d. h., die Methode oder der Konstruktor ist höchstens für andere Typen in derselben Assembly sichtbar, nicht jedoch für abgeleitete Typen außerhalb der 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

Eigenschaftswert

true, wenn die Sichtbarkeit dieser Methode oder dieses Konstruktors von Assembly genau beschrieben wird, andernfalls false.true if the visibility of this method or constructor is exactly described by Assembly; otherwise, false.

Implementiert

Beispiele

Im folgenden Codebeispiel werden Methoden mit unterschiedlichen Sichtbarkeits Ebenen definiert, und die Werte der IsAssemblyEigenschaften IsFamily, IsFamilyOrAssembly, und IsFamilyAndAssembly werden angezeigt.The following code example defines methods with varying levels of visibility, and displays the values of their IsAssembly, IsFamily, IsFamilyOrAssembly, and IsFamilyAndAssembly properties.

Hinweis

Die Visual Basic und C# Sprachen können keine Methoden mit MethodAttributes.FamANDAssem Sichtbarkeit definieren; diese Zugriffsebene wird nur C++ im Beispiel angezeigt.The Visual Basic and C# languages cannot define methods with MethodAttributes.FamANDAssem visibility; that access level appears only in the C++ example.

Hinweise

Die tatsächliche Sichtbarkeit einer Methode wird durch die Sichtbarkeit des Typs eingeschränkt.The actual visibility of a method is limited by the visibility of its type. Die IsAssembly -Eigenschaft kann true für eine Methode sein, aber wenn es sich um eine Methode eines privaten, nicht untergeordneten Typs handelt, ist die Methode außerhalb des enthaltenden Typs nicht sichtbar.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.

Die Sichtbarkeit einer Methode oder eines Konstruktors wird von MethodAttributes.Assembly genau beschrieben, wenn der einzige Sichtbarkeitsmodifizierer (Friend in Visual Basic) ist internal .The visibility of a method or constructor is exactly described by MethodAttributes.Assembly if the only visibility modifier is internal (Friend in Visual Basic). Diese Eigenschaft ist false für MethodenProtected Friend IsFamilyOrAssemblyin( in C++Visual Basic). verwenden Sie die-Eigenschaft, um solche Methoden zu identifizieren. protected public C# protected internalThis 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.
