Gets a value indicating whether the Type is declared public.

public:
 property bool IsPublic { bool get(); };

public bool IsPublic { get; }

member this.IsPublic : bool

Public ReadOnly Property IsPublic As Boolean

Property Value

Boolean

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

Implements

IsPublic

Examples

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

using namespace System;

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

int main()
{
   TestClass^ testClassInstance = gcnew TestClass;
   
   // Get the type of myTestClassInstance.
   Type^ testType = testClassInstance->GetType();
   
   // Get the IsPublic property of the myTestClassInstance.
   bool isPublic = testType->IsPublic;
   Console::WriteLine( "Is {0} public? {1}", testType->FullName, isPublic);
}

using System;

public class TestClass
{
}

public class Example
{
   public static void Main()
   {
      TestClass testClassInstance = new TestClass();
      // Get the type of myTestClassInstance.
      Type   testType = testClassInstance.GetType();
      // Get the IsPublic property of testClassInstance.
      bool isPublic = testType.IsPublic;
      Console.WriteLine("Is {0} public? {1}", testType.FullName, isPublic);
   }
}
// The example displays the following output:
//        Is TestClass public? True

type TestClass() = class end

let testClassInstance = TestClass()
// Get the type of myTestClassInstance.
let testType = testClassInstance.GetType()
// Get the IsPublic property of testClassInstance.
let isPublic = testType.IsPublic
printfn $"Is {testType.FullName} public? {isPublic}"
// The example displays the following output:
//        Is TestClass public? True

Public Class TestClass
End Class

Public Class Example
   Public Shared Sub Main()
      Dim testClassInstance As New TestClass()
      
      ' Get the type of testClassInstance.
      Dim testType As Type = testClassInstance.GetType()
      ' Get the IsPublic property of testClassInstance.
      Dim isPublic As Boolean = testType.IsPublic
      Console.WriteLine("Is {0} public? {1}", testType.FullName, isPublic)
   End Sub 
End Class 
' The example displays the following output:
'       Is TestClass public? True

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

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 true.

TypeAttributes.VisibilityMask selects the visibility attributes.
