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 bool IsNestedFamily { get; }

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
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";
