c#(asp.net) new与override的区别

class Base
{
public virtual void F1()
{
Console.WriteLine("Base's virtual function F1");
}
public virtual void F2()
{
Console.WriteLine("Base's virtual fucntion F2");
}
}
class Derived:Base
{
public override void F1()
{
Console.WriteLine("Derived's override function F1");
}
public new void F2()
{
Console.WriteLine("Derived's new function F2");
}
}
class Program
{
public static void Main(string[] args)
{
Base b1 = new Derived();
//由于子类覆盖了父类的方法，因此这里调用的是子类的F1方法。也是OO中多态的体现
b1.F1();
//由于在子类中用new隐藏了父类的方法，因此这里是调用了隐藏的父类方法
b1.F2();
}
}
