推荐答案

你很接近。

你可以做的是使用你的呼叫的返回值 DataGridViewRowCollection.Rows.Add（）方法，它是刚刚添加的行的索引值。

What you can do is use the return value of your call to DataGridViewRowCollection.Rows.Add() method, which is the index value of the just added row.

将代码更改为：

int RowIndex = lineItemsDGV.Rows.Add();
DataGridViewRow NewRow = lineItemsDGV.Rows[RowIndex];
NewRow.Cells[0].Value = item.Product_id;
NewRow.Cells[1].Value = item.product_name;
NewRow.Cells[2].Value = item.specification;
NewRow.Cells[3].Value = item.unit_price;
NewRow.Cells[4].Value = item.unit_price * 1;
