Answer 1

private void button2_Click(object sender, EventArgs e)
        {
            //选中DGV中的第一行
            this.dataGridView1.Rows[0].Selected = true; 
        }        private void button3_Click(object sender, EventArgs e)
        {
            //从DGV中移除第一行
            this.dataGridView1.Rows.Remove(this.dataGridView1.Rows[0]);
        }
