关于DataGridView控件部分的使用

if (e.ColumnIndex == 1)
{
m = e.RowIndex;
txt_startTime.Text = dgv_reserve.Rows[e.RowIndex].Cells[e.ColumnIndex].Value.ToString();
tc();
txt_endTime.Text = "";

dgv_reserve.Rows[e.RowIndex].Cells[1].Style.BackColor = Color.MediumOrchid;
//dgv_reserve.Rows[e.RowIndex].Cells[1].Style.SelectionBackColor = Color.Green;
for (int i = e.RowIndex; i >= 0; i--) //涂抹小于此开始时间的结束时间部分
{
if (DateTime.Parse(txt_startTime.Text) >= (DateTime)dgv_reserve.Rows[i].Cells[2].Value && dgv_reserve.Rows[i].Cells[2].Style.BackColor != Color.Red && dgv_reserve.Rows[i].Cells[1].Style.BackColor != Color.Red)
{
dgv_reserve.Rows[i].Cells[2].Style.BackColor = Color.Gray;
}
}
for (int i = e.RowIndex; i < dgv_reserve.RowCount; i++) //大于此开始时间的结束时间部分
