方法一(dataGridView1.CurrentRow.Index 按钮的点击事件):

        //按下按钮btn执行
        private void btnEdit_Click(object sender, EventArgs e)
        {
            try
            {
                if (dataGridView1.SelectedRows.Count > 0)
                {
                    int RowIndex = dataGridView1.CurrentRow.Index;
                    infrared_heat model = new infrared_heat();
                    model.UUID = Tools.ToString(this.dataGridView1.Rows[RowIndex].Cells[1].Value);
                    model.test_date = (DateTime)Tools.ToDateTime(this.dataGridView1.Rows[RowIndex].Cells[2].Value);
                    model.station_name = Tools.ToString(this.dataGridView1.Rows[RowIndex].Cells[3].Value);
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
        }

 方法二(e.RowIndex 双击或单击dataGridView行或单元格):

        //双击或单击dataGridView执行
        private void dataGridView1_CellDoubleClick(object sender, DataGridViewCellEventArgs e)
        {
            try
            {
                if (dataGridView1.SelectedRows.Count > 0)
                {
                    infrared_heat model = new infrared_heat();
                    model.UUID = Tools.ToString(this.dataGridView1.Rows[e.RowIndex].Cells[1].Value);
                    model.test_date = (DateTime)Tools.ToDateTime(this.dataGridView1.Rows[e.RowIndex].Cells[2].Value);
                    model.station_name = Tools.ToString(this.dataGridView1.Rows[e.RowIndex].Cells[3].Value);
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
