datagridview实现手动添加行数据

        int index = this.dataGridView1.Rows.Add();
        this.dataGridView1.Rows[index].Cells[0].Value = "1";
        this.dataGridView1.Rows[index].Cells[1].Value = "11";
        this.dataGridView1.Rows[index].Cells[2].Value = "1111";
        this.dataGridView1.Rows[index].Cells[3].Value = "11111";
        this.dataGridView1.Rows[index].Cells[4].Value = "111111";
        this.dataGridView1.Rows[index].Cells[5].Value = "1111111";
        this.dataGridView1.Rows[index].Cells[6].Value = "*-*";

dataGridView1.AutoGenerateColumns = true;
dataGridView1.DataSource = customersDataSet;

   songsDataGridView.ColumnCount = 5;
   ....
   songsDataGridView.Columns[0].Name = "Release Date";
   ....

string[] row0 = { "11/22/1968", "29", "Revolution 9", 
"Beatles", "The Beatles [White Album]" };
songsDataGridView.Rows.Add(row0);

this.dataGridView1.Rows[1].Cells[0].Value = "new value";
//或者，等价的
this.dataGridView1[0, 1].Value = "new value";
