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.
