Type.IsNestedFamily Property

Microsoft Silverlight will reach end of support after October 2021. Learn more.

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

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

Syntax

'Declaration
Public ReadOnly Property IsNestedFamily As Boolean

public bool IsNestedFamily { get; }

Property Value

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

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.

Examples

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

Note:
To run this example, see Building Examples That Use a Demo Method and a TextBlock Control.

' Enclose a class.
Class MyClassA

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

Class Example
   Inherits MyClassA

   Public Shared Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)
      ' Get the Type of the nested class.
      Dim myTypeB As Type = GetType(MyClassA.MyClassB)
      ' Get the 'IsNestedFamily' property the of the nested class
      ' 'Type'.
      outputBlock.Text &= (ControlChars.Cr + "The nested class has the property 'IsNestedFamily' value: " + myTypeB.IsNestedFamily.ToString()) & vbCrLf
   End Sub 'Main
End Class 'MyTestClass

// Enclose a class.
class MyClassA
{
   // Protected nested class.
   protected class MyClassB
   {
   }
}
class Example : MyClassA
{
   public static void Demo(System.Windows.Controls.TextBlock outputBlock)
   {
      // Get the Type of the nested class.
      Type myTypeB = typeof(MyClassA.MyClassB);
      // Get the 'IsNestedFamily' property the of the nested class
      // 'Type'.
      outputBlock.Text += "\nThe nested class has the property 'IsNestedFamily' value: " +
                        myTypeB.IsNestedFamily.ToString() + "\n";
   }
}
