systemarray用于數組元素排序的方法？

其實就是讓你寫一個類，實現IComparable接口，再通過調用Sort方法對該類的實例（一維數組）排序。 class Student:IComparable { private string name; private int score; public int CompareTo(object obj) { Student _obj = obj as Student; if (_obj != null) { return this.score.CompareTo(_obj.score); } else throw new ArgumentException("Object is not a Student !"); } }
