C# 如何在c语言中对datagridview中的数据进行降序排序#

所以我想把我的txtCourse和txtTimeslot填入datagridview， 然后对txtTimeslot进行降序排序，并在datagridview中显示txtCourse和txtTimeslot

string firstColum = txtCourse.Text;
string secondColum = txtTimeslot.Text;
string[] row = { firstColum, secondColum };

dgvLSD.Rows.Add(row);

我已将txtCourse和txtTimeslot填充到datagridview中

string firstColum = txtCourse.Text;
string secondColum = txtTimeslot.Text;
string[] row = { firstColum, secondColum };

dgvLSD.Rows.Add(row);

我需要知道如何将txtTimeslot按降序排序，并将txtCourse和txtTimeslot显示在datagridview中

将列的

SortMode

属性设置为

Automatic

它已经处于自动模式

string firstColum = txtCourse.Text;
string secondColum = txtTimeslot.Text;
string[] row = { firstColum, secondColum };

dgvLSD.Rows.Add(row);
