Implements

_Type::IsSealed

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

The following example creates an instance of a sealed class, checks for the IsSealed property, and displays the result.

using namespace System;

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

int main()
{
      TestClass^ testClassInstance = gcnew TestClass;

      // Get the type of testClassInstance.
      Type^ type = testClassInstance->GetType();

      // Get the IsSealed property of the myTestClassInstance.
      bool sealed = type->IsSealed;
      Console::WriteLine("{0} is sealed: {1}.", type->FullName, sealed);
}
// The example displays the following output:
//        TestClass is sealed: True.
