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)

public bool IsNested { get; }

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.


using System;

public class Example
{
    protected class NestedProtected
    {
    }

    public class NestedPublic
    {
    }

    public static void Main()
    {
        Type t = typeof(NestedProtected);
        Console.WriteLine("Is {0} nested? {1}", t.FullName, t.IsNested);
        t = typeof(NestedPublic);
        Console.WriteLine("Is {0} nested? {1}", t.FullName, t.IsNested);
    }
}

/* This example produces the following output:

Is Example+NestedProtected nested? True
Is Example+NestedPublic nested? True 
 */
