new 与override 区别

?

1 2 3 4 5 6

BaseC baseC=new BaseC ();             baseC.Invoke();             BaseC derivedC =new DerivedC ();              derivedC.Invoke();             SuperA superA = new SuperA(); //new 必须申明也是本类             superA.Invoke();BaseC superA1 = new SuperA(); //申明是父类<br> superA1.Invoke();

　输出如下：　

　　　　BaseC
　　　　DerivedC
　　　　SuperA
　　　　BaseC //申明是父类

new 隐藏父类，而申明必须也是子类才可以。
