DataGridView -- 我的记录

private void btnDel_Click(object sender, EventArgs e)
{
    //无需i++, 因为每Remove一个选择行后, SelectedRows.Count自动减1
    for (int i = 0; i < dgvBrand.SelectedRows.Count; )
    {
        //SelectedRows[0] ~ SelectedRows[SelectedRows.Count-1] 从删除行的尾行至首行
        int index = dgvBrand.SelectedRows[dgvBrand.SelectedRows.Count - 1].Index;
        dgvBrand.Rows.RemoveAt(index);
    }
}
