Type.IsNested Property

Gets a value indicating whether the current Type object represents a type whose definition is nested inside the definition of another type.

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

'Declaration
Public ReadOnly Property IsNested As Boolean

Property Value

Type: System.Boolean
true if the Type is nested inside another type; otherwise, false.

The IsNested property returns true for all nested types, regardless of visibility. To test for nesting and visibility at the same time, use the related properties IsNestedAssembly, IsNestedFamily, IsNestedFamANDAssem, IsNestedFamORAssem, IsNestedPrivate, or IsNestedPublic.

NoteNote

The VisibilityMask enumeration member selects the visibility attributes for a type.

The following code example displays the value of the IsNested property for both a protected nested class and a public nested class.


Imports System

Public Class Example
    Protected Class NestedProtected
    End Class

    Public Class NestedPublic
    End Class

    Public Shared Sub Main()
        With GetType(NestedProtected)
            Console.WriteLine("Is " & .FullName & " nested? " & .IsNested)
        End With
        With GetType(NestedPublic)
            Console.WriteLine("Is " & .FullName & " nested? " & .IsNested)
        End With
    End Sub
End Class

' This example produces the following output:
'
'Is Example+NestedProtected nested? True
'Is Example+NestedPublic nested? True
