自定义类排序

直接上代码

using System;
using System.Collections.Generic;
using System.Text;
using System.Collections;

namespace 自定义类排序
{
//可以让类继承
class Person:IComparable {
public string Name { get; set; }
public bool Sex { get; set; }
public int Age { get; set; }
public Person(string name,bool sex,int age) {
Name = name;
Sex = sex;
Age = age;
}
//实现IComparable
public int CompareTo(object obj) {
Person p = obj as Person;
//逻辑
int iReturn = this.Name.CompareTo(p.Name);
if (iReturn == 0) {
iReturn= this.Age.CompareTo(p.Age);
}
return iReturn;
}
}

//比较排序
class PersonSort : IComparer<Person>
{

#region IComparer<Person> 成员

public int Compare(Person p1, Person p)
{
int iReturn = p1.Name.CompareTo(p.Name);
if (iReturn == 0)
{
iReturn = p1.Age.CompareTo(p.Age);
}
return iReturn;
}

#endregion
}

//根据名字排序 如果名字相同按 年龄

一种是类实现接口ICompareable  另一种是 IComparer<Person>实现比较的接口 关键词 ：Compare
