C# list 多条件排序

private int SortByID(HorseDate a1, HorseDate a2)
{
            if (a1.level.CompareTo(a2.level) != 0)
                return -(a1.level.CompareTo(a2.level));
            else if (a1.ToLevel.CompareTo(a2.ToLevel) != 0)
                return -(a1.ToLevel.CompareTo(a2.ToLevel));
        else if (a1.Quality.CompareTo(a2.Quality) != 0)
                return -(a1.Quality.CompareTo(a2.Quality));
        else if (a1.ID.CompareTo(a2.ID) != 0)
                return -(a1.ID.CompareTo(a2.ID));
            else
                return 1;
}

程序中直接调用

horseList,.Sort(SortByID);

最后，有人注意到为何return返回的降序吗？哈哈，由于前面提到过这个功能是要按照降序排列的，因此前面须要加负号，若是是升序排列就不须要了
