IsNotPublic Property

Type.IsNotPublic Property

Gets a value indicating whether the Type is not declared public.

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

public bool IsNotPublic { get; }

Property Value

Type: System.Boolean
true if the Type is not declared public and is not a nested type; otherwise, false.

Implements

_Type.IsNotPublic

Do not use this property with nested types; use the IsNestedPublic property instead.

If the current Type represents a type parameter of a generic type, this property returns false.

This example uses the IsNotPublic property to get the visibility of the type.

using System;
using System.IO;
using System.Reflection;

class Example
{ 
    public static void Main()
    { 
        // Get the Type and MemberInfo.
        Type t = Type.GetType("System.IO.File");
        MemberInfo[] members = t.GetMembers();
        // Get and display the DeclaringType method.
        Console.WriteLine("\nThere are {0} members in {1}.",
                          members.Length, t.FullName);
        Console.WriteLine("Is {0} non-public? {1}",
                          t.FullName, t.IsNotPublic);
    }
}
// The example displays output like the following: 
//       There are 60 members in System.IO.File. 
//       Is System.IO.File non-public? False

The following code example demonstrates why you cannot use IsPublic and IsNotPublic for nested classes.

public class A 
{
    public class B { }
    private class C { }
}

For nested classes, ignore the results of IsPublic and IsNotPublic and pay attention only to the results of IsNestedPublic and IsNestedPrivate. The reflection output for this code fragment would be as follows:
