            {
                for (int j = 0; j < dataGridView1.Columns.Count; j++)
                {
                    var Value = Convert.ToString(dataGridView1.Rows[i].Cells[j].Value);
                    if (Value == "Temp01")
                    {
                        dataGridView1.Rows[i].Cells[j].Selected = true; //找到后单元zhi格被dao选中
