设计一个类，类名为person，此类具有属性（name,age,sex）,设计person的子类teacher，具有属性（teacher_years,professional）,设计person的子类saler,具有属性（work_years,sale）,在main中创建不同的集合，存放teacher的对象和saler的对象，并按照teacher的teacher_years排序输出集合中的对象，按照saler的work_years排序输出集合中的对象。 --------------------编程问答-------------------- public class person{
public person()

public teacher Teacher

public saler Saler

//同上
} --------------------编程问答-------------------- 那数据类型是那些啊？ --------------------编程问答-------------------- 这个自己写写比较好~ --------------------编程问答-------------------- 好用～顶！！ --------------------编程问答-------------------- 个人觉得使用接口System.IComparable不好。你还不如直接用op <, op >, op ==呢

赞同，自己写体会的比较深刻
补充：.NET技术 , .NET Framework
