Type.IsNestedPublic 属性

定义

获取一个值,通过该值指示类是否是嵌套的并且声明为公共的。Gets a value indicating whether a class is nested and declared public.

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

属性值

如果类是嵌套的并且声明为公共的,则为true ;否则为 falsetrue if the class is nested and declared public; otherwise, false.

实现

示例

下面的示例创建一个外部类,其中包含多个具有不同类型的可见性的嵌套类。The following example creates an outer class with a number of nested classes that have various types of visibility. 然后,它检索父类型及其每个嵌套类型的多个与可见性相关的 Type 属性的值。It then retrieves the value of a number of visibility-related Type properties for the parent type and each of its nested types.

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);
        }
    }
}

注解

如果当前 Type 表示泛型类型的类型参数,则此属性始终返回 falseIf the current Type represents a type parameter of a generic type, this property always returns false.
