Console.WriteLine("Private component called successfully."); } } public class PrivateComponentAttribute_Test : ServicedComponent { public void Test() { // Create a new instance of the example class. PrivateComponentAttribute_Example example = new PrivateComponentAttribute_Example(); // Call a method on the class. example.Example(); } }
