Type.IsNotPublic Property (System)

.NET Framework Class Library

Type..::.IsNotPublic Property

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

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

Syntax

Visual Basic (Declaration)

Public ReadOnly Property IsNotPublic As Boolean

Visual Basic (Usage)

Dim instance As Type
Dim value As Boolean

value = instance.IsNotPublic

public bool IsNotPublic { get; }

Visual C++

public:
virtual property bool IsNotPublic {
    bool get () sealed;
}

JScript

public final function get IsNotPublic () : boolean

Property Value

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

Implements

_Type..::.IsNotPublic

Remarks

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.

Examples

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

Visual Basic

Imports System
Imports System.IO
Imports System.Reflection
Imports Microsoft.VisualBasic
Class MyMemberInfo
    Public Shared Sub Main()
        Console.WriteLine(ControlChars.Cr + "Reflection.MemberInfo")
        'Get the Type and MemberInfo.
        Dim MyType As Type = Type.GetType("System.IO.File")
        Dim Mymemberinfoarray As MemberInfo() = MyType.GetMembers()
        'Get and display the DeclaringType method.
        Console.WriteLine(ControlChars.Cr + "There are {0} members in {1}.", _
           Mymemberinfoarray.Length, MyType.FullName)
        Console.WriteLine("Is {0} nonpublic? {1}", MyType.FullName, _
           MyType.IsNotPublic.ToString())
    End Sub
End Class

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());
    }
}

Visual C++

using namespace System;
using namespace System::IO;
using namespace System::Reflection;
int main()
{
   Console::WriteLine( "\nReflection.MemberInfo" );

   //Get the Type and MemberInfo.
   Type^ MyType = Type::GetType( "System.IO.File" );
   array<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 );
}

JScript

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.

Visual Basic

Public Class A
    Public Class B
    End Class
    Private Class C
    End Class
End Class

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

Visual C++

public ref class A
{
public:
   ref class B{};


private:
   ref class C{};


};

JScript

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:

Class	IsNotPublic	IsPublic	IsNestedPublic	IsNestedPrivate
A	FALSE	TRUE	FALSE	FALSE
B	FALSE	FALSE	TRUE	FALSE
C	FALSE	FALSE	FALSE	TRUE
