Type.IsPublic Property

Gets a value indicating whether the Type is declared public.

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

virtual property bool IsPublic {
	bool get () sealed;
/** @property */
public final boolean get_IsPublic ()

public final function get IsPublic () : boolean

Not applicable.

Property Value

true if the Type is 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 true.

TypeAttributes.VisibilityMask selects the visibility attributes.

The following example creates an instance of MyTestClass, checks for the IsPublic property, and displays the result.

using namespace System;

namespace SystemType

   // Declare MyTestClass as public.
   public ref class MyTestClass{};

   public ref class MyClass{};


int main()
      bool myBool = false;
      SystemType::MyTestClass^ myTestClassInstance = gcnew SystemType::MyTestClass;
      // Get the type of myTestClassInstance.
      Type^ myType = myTestClassInstance->GetType();
      // Get the IsPublic property of the myTestClassInstance.
      myBool = myType->IsPublic;
      Console::WriteLine( "\nIs {0} public? {1}.", myType->FullName, myBool.ToString() );
   catch ( Exception^ e ) 
      Console::WriteLine( "\nAn exception occurred: {0}", e->Message );


package SystemType; 

import System.*;

// Declare MyTestClass as public.
public class MyTestClass
} //MyTestClass

public class MyClass
    public static void main(String[] args)
        try {
            boolean myBool = false;
            MyTestClass myTestClassInstance = new MyTestClass();

            // Get the type of myTestClassInstance.
            Type myType = myTestClassInstance.GetType();

            // Get the IsPublic property of the myTestClassInstance.
            myBool = myType.get_IsPublic();
            Console.WriteLine("\nIs {0} public? {1}.", myType.get_FullName(),
        catch (System.Exception e) {
            Console.WriteLine("\nAn exception occurred: {0}", e.get_Message());
    } //main
} //MyClass

For nested classes, ignore the results of IsPublic and IsNotPublic and pay attention only to the results of IsNestedPublic and IsNestedPrivate.
