Definición
Importante
Parte de la información hace referencia a la versión preliminar del producto, que puede haberse modificado sustancialmente antes de lanzar la versión definitiva. Microsoft no otorga ninguna garantía, explícita o implícita, con respecto a la información proporcionada aquí.
Obtiene un valor que indica si el objeto Type actual representa un tipo cuya definición está anidada dentro de la definición de otro tipo.
public:
property bool IsNested { bool get(); };
public bool IsNested { get; }
member this.IsNested : bool
Public ReadOnly Property IsNested As Boolean
Valor de propiedad
Es true
si Type está anidado dentro de otro tipo; de lo contrario, es false
.
Ejemplos
En el ejemplo siguiente se crea una clase externa con una serie de clases anidadas que tienen varios tipos de visibilidad. A continuación, recupera el valor de una serie de propiedades relacionadas con Type la visibilidad para el tipo primario y cada uno de sus tipos anidados.
using System;
// Create a class with a number of nested classes.
public class OuterClass
{
private class PrivateClass
{}
protected class ProtectedClass
{}
internal class InternalClass
{}
protected internal class ProtectedInternalClass
{}
public class PublicClass
{}
public static void Main()
{
// Create an array of Type objects for all the classes.
Type[] types = { typeof(OuterClass),
typeof(OuterClass.PublicClass),
typeof(OuterClass.PrivateClass),
typeof(OuterClass.ProtectedClass),
typeof(OuterClass.InternalClass),
typeof(OuterClass.ProtectedInternalClass) };
// Display the property values of each nested class.
foreach (var type in types) {
Console.WriteLine("\n{0} property values:", type.Name);
Console.WriteLine(" Public Class: {0}", type.IsPublic);
Console.WriteLine(" Not a Public Class: {0}", type.IsNotPublic);
Console.WriteLine(" Nested Class: {0}", type.IsNested);
Console.WriteLine(" Nested Private Class: {0}", type.IsNestedPrivate);
Console.WriteLine(" Nested Internal Class: {0}", type.IsNestedAssembly);
Console.WriteLine(" Nested Protected Class: {0}", type.IsNestedFamily);
Console.WriteLine(" Nested Family Or Assembly Class: {0}", type.IsNestedFamORAssem);
Console.WriteLine(" Nested Family And Assembly Class: {0}", type.IsNestedFamANDAssem);
Console.WriteLine(" Nested Public Class: {0}", type.IsNestedPublic);
}
}

Comentarios
La IsNested propiedad devuelve true
para todos los tipos anidados, independientemente de la visibilidad. Para probar el anidamiento y la visibilidad al mismo tiempo, use las propiedades IsNestedAssemblyrelacionadas , IsNestedFamily, IsNestedFamANDAssem, IsNestedFamORAssem, IsNestedPrivateo IsNestedPublic.
Nota:
El VisibilityMask miembro de enumeración selecciona los atributos de visibilidad de un tipo.
