怎么获dataGridView中的数据

dgv.Rows[e.RowIndex].Cells["NAME"].Value.ToString();

private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
        {
            string tmpDisplay = string.Empty;
            for (int i = 0; i < this.dataGridView1.ColumnCount; i++)
            {
                tmpDisplay = tmpDisplay + this.dataGridView1.Rows[e.RowIndex].Cells[i].Value.ToString();
            }
            MessageBox.Show(tmpDisplay);
        }
