C#实现Comparable接话把现排序

C#实现Comparable接口实现排序

C#中，实现排序的方法有两种，即实现Comparable或Comparer接口，下面简单介绍实现Comparable接口实现排序功能。

实现Comparable接口需要实现CompareTo(object obj)方法，所以简单实现这个方法就可以很方便的调用其排序功能。

以Student的score为例，进行排序：

具体代码：

using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace ConsoleApplicationtest{    class Program    {        public class Student:IComparable        {            int _socre;            string _name;            public int score            {                set { _socre = value; }                get { return _socre; }            }            public string name            {                set { _name = value; }                get { return _name; }            }            public void Display()            {                Console.WriteLine("姓名：{0}\t分数：{1}",_name,_socre);            }            public int CompareTo(object obj)//实现接口            {                Student stu = (Student)obj;                return this._socre - stu._socre;            }        }        static void Main(string[] args)        {            List<Student> stuList = new List<Student>();            stuList.Add(new Student() { score = 98, name = "Bob" });            stuList.Add(new Student() { score = 56, name = "Alice" });            stuList.Add(new Student() { score = 100, name = "Jerry" });            Console.WriteLine("排序前：");            foreach (Student mystu in stuList)            {                mystu.Display();            }            stuList.Sort();            Console.WriteLine("\n排序后：");            foreach (Student mystu in stuList)            {                mystu.Display();            }            Console.ReadKey();        }    }}
