推荐答案

如果您需要10到20之间的商品，请使用此类数字，例如

If you need items from 10 to 20 then use such numbers, e.g.

For i as Integer = 10 to 20

另一方面，如果您需要最后11项，请输入:

On the other hand, if you need last 11 items, then write:

Dim last as Integer = listbox1.Items.Count-1
For i as Integer = (last-10) to last 

当然，您必须检查边缘情况.

Of course you have to check for edge cases.
