Aşağıdaki örnek, bir sınıfının bir örneğini oluşturur sealed , IsSealed özelliği denetler ve sonucu görüntüler.

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.

using System;

 public class Example
 {
     // Declare InnerClass as sealed.
     sealed public class InnerClass
     {
     }

     public static void Main()

          InnerClass inner = new InnerClass();
          // Get the type of InnerClass.
          Type innerType = inner.GetType();
          // Get the IsSealed property of  innerClass.
          bool isSealed = innerType.IsSealed;
          Console.WriteLine("{0} is sealed: {1}.", innerType.FullName, isSealed);
     }
}
// The example displays the following output:
//        Example+InnerClass is sealed: True.

Public Class Example
