Type.IsNestedFamily Property

Gets a value indicating whether the Type is nested and visible only within its own family.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

Public ReadOnly Property IsNestedFamily As Boolean

Property Value

Type: System.Boolean
true if the Type is nested and visible only within its own family; otherwise, false.



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.

The following code example demonstrates how to use the IsNestedFamily property to determine whether a type is both nested and protected.

' Enclose a class. 
Class MyClassA

  ' Protected nested class. 
   Protected Class MyClassB
   End Class 'MyClassB
End Class 'MyClassA

Class MyTestClass
   Inherits MyClassA

   Public Shared Sub Main()
      ' Get the Type of the nested class. 
      Dim myTypeB As Type = GetType(MyClassA.MyClassB)
      ' Get the 'IsNestedFamily' property the of the nested class 
      ' 'Type'.
      Console.WriteLine((ControlChars.Cr + "The nested class has the property 'IsNestedFamily' value: " + myTypeB.IsNestedFamily.ToString()))
   End Sub 'Main
End Class 'MyTestClass
