private void gridView1_RowStyle(object sender, RowStyleEventArgs e)
{

            //读取使用年限值
            SqlDataReader sqlread = database.getread("select Pjmc,Synx from tb_Synx");
            if (sqlread.Read())
            {
                lab_Synx.Text = sqlread["Synx"].ToString();
                lab_Pjmc.Text = sqlread["Pjmc"].ToString();



                sqlread.Close();
            }
                GridView View = sender as GridView;
                if (e.RowHandle >= 0)
                {
                    int year = Convert.ToInt32(lab_Synx.Text);
                    string pjmc = View.GetRowCellDisplayText(e.RowHandle, View.Columns["Pjmc"]);
