简单介绍如何为DataGridView控件动态添加新行的两种方 法：
方法一：
int index=this.dataGridView1.Rows.Add();
this.dataGridView1.Rows[index].Cells[0].Value = "1";
this.dataGridView1.Rows[index].Cells[1].Value = "2";
this.dataGridView1.Rows[index].Cells[2].Value = "监听";
方法二：
DataGridViewRow
row = new DataGridViewRow();
DataGridViewTextBoxCell textboxcell = new DataGridViewTextBoxCell();
textboxcell.Value = "aaa";
row.Cells.Add(textboxcell);
DataGridViewComboBoxCell comboxcell = new DataGridViewComboBoxCell();
row.Cells.Add(comboxcell);
dataGridView1.Rows.Add(row);
