Gets a value indicating whether the Type is nested and visible only within its own family.
public:
property bool IsNestedFamily { bool get(); };
public bool IsNestedFamily { get; }
member this.IsNestedFamily : bool
Public ReadOnly Property IsNestedFamily As Boolean
Property Value
true
if the Type is nested and visible only within its own family; otherwise, false
.

Examples
The following example creates an outer class with a number of nested classes that have various types of visibility. 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);
}
}

Remarks
If the current Type represents a type parameter of a generic type, this property always returns false
.
TypeAttributes.VisibilityMask selects the visibility attributes.
A Type object's family is defined as all objects of the exact same Type and of its subtypes.
