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 */
public final boolean get_IsNotPublic ()

public final function get IsNotPublic () : boolean

Property Value

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

Do not use with nested types; use IsNestedPublic instead.

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

TypeAttributes.VisibilityMask selects the visibility attributes.

This example shows the use of IsNotPublic to get the visibility of the type.

using System;
using System.IO;
using System.Reflection;
class MyMemberInfo 
{ 
    public static void Main(string[] args) 
    { 
        Console.WriteLine ("\nReflection.MemberInfo");
        //Get the Type and MemberInfo.
        Type MyType =Type.GetType("System.IO.File");
        MemberInfo[] Mymemberinfoarray = MyType.GetMembers();
        //Get and display the DeclaringType method.
        Console.WriteLine("\nThere are {0} members in {1}.", Mymemberinfoarray.Length, MyType.FullName);
        Console.WriteLine("Is {0} nonpublic? {1}", MyType.FullName, MyType.IsNotPublic.ToString());
    }
}

import System.*;
import System.IO.*;
import System.Reflection.*;

class MyMemberInfo
{
    public static void main(String[] args)
    {
        Console.WriteLine("\nReflection.MemberInfo");

        //Get the Type and MemberInfo.
        Type myType = Type.GetType("System.IO.File");
        MemberInfo mymemberinfoarray[] = myType.GetMembers();

        //Get and display the DeclaringType method.
        Console.WriteLine("\nThere are {0} members in {1}.", 
            System.Convert.ToString(mymemberinfoarray.length),
            myType.get_FullName());
        Console.WriteLine("Is {0} nonpublic? {1}", myType.get_FullName(),
            System.Convert.ToString(myType.get_IsNotPublic()));
    } //main
} //MyMemberInfo

import System;
import System.IO;
import System.Reflection;

class MyMemberInfo { 

  public static function Main() : void  { 

   Console.WriteLine ("\nReflection.MemberInfo");

   //Get the Type and MemberInfo 

   var MyType : Type =Type.GetType("System.IO.File");

   var Mymemberinfoarray : MemberInfo[] = MyType.GetMembers();

   //Get and display the DeclaringType method

   Console.WriteLine("\nThere are {0} members in {1}.",
      Mymemberinfoarray.Length, MyType.FullName);

   Console.WriteLine("Is {0} public? {1}", MyType.FullName,
      MyType.IsPublic.ToString());
  }
}
MyMemberInfo.Main();

This code produces the following output:

There are 27 members in System.IO.File.

Is System.IO.File 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 { }
}

public class A
{
    public class B
    {
    } //B

    private class C
    {
    } //C
} //A 

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:

IsPublic
