建议10:必须知道如何实现类比较器 接口实现对象排序

public class Salary : IComparable<Salary>
        {
            public int RMB { get; set; }

            public int CompareTo(Salary obj)

                }
            }

List<Salary> salarys = new List<Salary>();
            for (int i = 0; i < 5; i++)

                Salary salary = new Salary() {RMB=100*i };
                salarys.Add(salary);
