winformのdatagridviewはリストにバインドされ、昇順と降順を実装します

#region  实现降序排序
    class NameDESC : IComparer<Student>
    {
        public int Compare(Student x, Student y)
        {
            return y.StudentName.CompareTo(x.StudentName);
        }
    }

    class StudentDESC : IComparer<Student>
    {
        public int Compare(Student x, Student y)
        {
            return y.StudentId.CompareTo(x.StudentId);
        }
    }
    #endregion
