C# 编程/关键字/new

来自 Wikibooks,开放世界中的开放书籍

new 关键字有两个不同的含义

  1. 它是一个运算符,它请求由其参数标识的类的新的实例。
  2. 它是一个修饰符,它明确地隐藏了成员。

例如,请参见下面的代码

public class Car
{
    public void go()
    {
    }
}

Car theCar = new Car();       // The new operator creates a Car instance

int i = new int();            // Identical to … = 0;

public class Lamborghini : Car
{
    public new void go()      // Hides Car.go() with this method
    {
    }
}
