详细介绍C#中new的几种用法

using System;

 public class MyBaseC

 {

 public class MyClass

 {

 public int x = 200;

 public int y;

 }

 }

 public class MyDerivedC : MyBaseC

 {

 new public class MyClass // nested type hiding the base type members

 {

 public int x = 100;

 public int y;

 public int z;

 }

 public static void Main()

{

 // Creating object from the overlapping class:

 MyClass S1 = new MyClass();

 // Creating object from the hidden class:

MyBaseC.MyClass S2 = new MyBaseC.MyClass();

 Console.WriteLine(S1.x);

 Console.WriteLine(S2.x);

 }

 }
