C＃ 36. DataGridView行号

1. 选择一行触发一个事件

private System.Windows.Forms.DataGridView dataGridView1;    
private void dataGridView1_RowHeaderMouseClick(object sender, DataGridViewCellMouseEventArgs e)
{
    
	int index = e.RowIndex;	//0,1,2.... 0xffffffff：清空时
}

2. 直接获取单元格所在行号

int index = dataGridView1.CurrentCell.RowIndex;
