推荐答案

使用Linq

Use Linq

lv3.Items.Add(lv2.Items.Except(lv1.Items).Union(lv1.Items.Except(lv2.Items)))

从Listview2中逐一删除项目.
在ListView1中搜索.
如果找不到，则将其添加到Listview3中.

这是什么问题?

Take one by one items from Listview2.
Search it in ListView1.
If not found then add that item in Listview3.

What is the problem in this?
