通过单击标题对DataGridView进行排序的C#给出了错误的顺序

private void dataGridView1_ColumnHeaderMouseClick(object sender, DataGridViewCellMouseEventArgs e)
{
    DataGridViewColumn clickedColumn = dataGridView1.Columns[e.ColumnIndex];
    
    // 获取当前排序顺序
    SortOrder currentSortOrder = clickedColumn.HeaderCell.SortGlyphDirection;
    
    // 切换排序顺序
    if (currentSortOrder == SortOrder.Ascending)
    {
        clickedColumn.HeaderCell.SortGlyphDirection = SortOrder.Descending;
    }
    else
    {
        clickedColumn.HeaderCell.SortGlyphDirection = SortOrder.Ascending;
    }
    
    // 执行排序
    dataGridView1.Sort(dataGridView1.Columns[e.ColumnIndex], currentSortOrder == SortOrder.Ascending ? ListSortDirection.Ascending : ListSortDirection.Descending);
}
