泛型排序 问题

Question

问题如下
现要对一组数据(name,age,score)进行排序处理，并分别对age,score进行排序
    public class Person : IComparable<Person>
    {
        string name;
        int age;
        int score;
        public Person(string s, int i,int sc)
        {
            name = s;
            age = i;
            score = sc;
        }
        public int CompareTo(Person p)
        {
                return age - p.age;//现在可以对age进行排序，下一句对score排序，但无法调用
           // return score - p.score;
        }
        public override string ToString()
        {
            return name + ":" + age+" scroe:"+score;
        }
        public bool Equals(Person p)
        {
            return (this.age == p.age || this.score==p.score);
        }
    }
    // 尖括号中的类型参数 T。
    public class MyList<T> : IEnumerable<T>
    {
        protected Node head;
        protected Node current = null;        protected class Node
        {
            public Node next;
            private T data;
            public Node(T t)
            {
                next = null;
                data = t;
            }
            public Node Next
            {
                get { return next; }
                set { next = value; }
            }
            public T Data
            {
                get { return data; }
                set { data = value; }
            }
        }        public MyList()
        {
            head = null;
        }
        public void AddHead(T t)
        {
            Node n = new Node(t);
            n.Next = head;
            head = n;
        }
        public IEnumerator<T> GetEnumerator()
        {
            Node current = head;            while (current != null)
            {
                yield return current.Data;
                current = current.Next;
            }
        }
        IEnumerator IEnumerable.GetEnumerator()
        {
            return GetEnumerator();
        }
 
    }    public class SortedList<T> : MyList<T> where T : IComparable<T>
    {
        public void BubbleSort()
        {
            if (null == head || null == head.Next)
                return;            bool swapped;
            do
            {
                Node previous = null;
                Node current = head;
                swapped = false;                while (current.next != null)
                {
                    if (current.Data.CompareTo(current.next.Data) > 0)
                    {
                        Node tmp = current.next;
                        current.next = current.next.next;
                        tmp.next = current;                        if (previous == null)
                        {
                            head = tmp;
                        }
                        else
                        {
                            previous.next = tmp;
                        }
                        previous = tmp;
                        swapped = true;
                    }                    else
                    {
                        previous = current;
                        current = current.next;
                    }                }// 结束 while
            } while (swapped);
        }
    }       static void Main(string[] args)
        {
            SortedList<Person> list = new SortedList<Person>();
            string[] names = new string[] { "Franscoise", "Bill", "Li", "Sandra", "Gunnar", "Alok", "Hiroyuki", "Maria", "Alessandro", "Raul" };
            int[] ages = new int[] { 45, 19, 28, 23, 18, 9, 108, 72, 30, 35 };
            int[] scores = new int[] { 90, 40, 28, 23, 18, 56, 108, 44, 30, 23 };            for (int x = 0; x < names.Length; x++)
            {
                list.AddHead(new Person(names[x], ages[x],scores[x]));
            }
            // 对列表进行排序。
            list.BubbleSort();
         }

Answer 1

        public int CompareTo(Person p) 
        { 
             if(this.age == p.age)
                 return this.score.CompareTo(p.score);
             return this.age.CompareTo(p.age);
        } 

Answer 2

你蓝色注释的那个地方，是什么意思？你“分别对age,score进行排序 ”怎么理解，是对二者分别进行排序，还是当age相等时，再比较score？

Answer 3

排序方法是BubbleSort() 
其要调用public int CompareTo(Person p) 方法有比较结果
如果是按age排序则是取age - p.age的比较值，如果是按要CompareTo(Person p)返回return score - p.score; 
我对CompareTo（）方法进行重载也不行

Answer 4

public class Person Comparer : IComparer<Person >
{
    public enum CompareType
    {
        Name,
        Age
    }    private CompareType type;
    public StudentComparer(CompareType type)
    {
        this.type = type;
    }
    public int Compare(Person  x, Person y)
    {
        switch(this.type)
        {
            case CompareType.Name:
                return x.Name.CompareTo(y.Name);
            case CompareType.Age:
                return x.Age.CompareTo(y.Age);
            default:
                return x.Age.CompareTo(y.Age);
        }
    }
}

Answer 5

SortedList 是系统自带的一个类，你就算要自己写一个，也别用同名啊。其实完全可以用系统的排序类。
