ICloneable接口创建现有对象的副本,即克隆。
它只有一个方法-
Clone()-该clone()
方法创建一个新对象,该对象是当前实例的副本。
以下是显示如何使用Icloneable接口执行克隆的示例-
using System; class Car : ICloneable { int width; public Car(int width) { this.width = width; } public object Clone() { return new Car(this.width); } public override string ToString() { return string.Format("Width of car = {0}",this.width); } } class Program { static void Main() { Car carOne = new Car(1695); Car carTwo = carOne.Clone() as Car; Console.WriteLine("{0}mm", carOne); Console.WriteLine("{0}mm", carTwo); } }
输出结果
Width of car = 1695mm Width of car = 1695mm
