Type.IsNestedFamANDAssem 属性
定义
重要
一些信息与预发行产品相关,相应产品在发行之前可能会进行重大修改。 对于此处提供的信息,Microsoft 不作任何明示或暗示的担保。
获取一个值,通过该值指示 Type 是否是嵌套的并且只对同时属于自己家族和自己程序集的类可见。
public:
property bool IsNestedFamANDAssem { bool get(); };
public bool IsNestedFamANDAssem { get; }
member this.IsNestedFamANDAssem : bool
Public ReadOnly Property IsNestedFamANDAssem As Boolean
属性值
如果 Type 是嵌套的并且只对同时属于它自己的家族和它自己的程序集的类可见,则为 true
;否则为 false
。
实现
示例
以下示例创建一个外部类,其中包含许多嵌套类,这些类具有各种类型的可见性。 然后,它检索父类型及其每个嵌套类型的许多与可见性相关的 Type 属性的值。
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 false
。
TypeAttributes.VisibilityMask 选择可见性属性。
注意
C# 和 Visual Basic 语言不包括允许定义仅对其程序集中的受保护类型可见的嵌套类型的语义。
protected internal
C# 中的 visibility 和 Protected Friend
Visual Basic 中的可见性定义了一个嵌套类型,该类型对受保护的类型和同一程序集中的类型都可见。
对象的 Type 系列定义为相同 Type 及其子类型的所有对象。
