你可以通过多种方式实现。

You can do it by many ways.

int sum = 0;
for (int i = 0; i < dataGridView1.Rows.Count; ++i)
{
    sum += Convert.ToInt32(dataGridView1.Rows[i].Cells[1].Value);
}

你可以使用Linq

You can use Linq

int sum= dataGridView1.Rows.Cast<datagridviewrow>()
                .Sum(t => Convert.ToInt32(t.Cells[1].Value));

，最后你可以在gridview上添加一行，或者你可以在Label中显示总和结果。

and finally you can add a Row on your gridview or you can show sum result in Label .
