推荐答案

你有什么疑问？

迭代（明智地：你要删除物品）您可以使用查找 [< a href =http://msdn.microsoft.com/en-us/library/system.windows.forms.listview.listviewitemcollection.find.aspxtarget =_ blanktitle =New Window> ^ ]获取与当前项目匹配的项目数组，并依次对这样的数组进行处理，删除与子项目匹配的项目。

尝试（我没有测试过）：

Dim i as Integer = 0

And what's your doubt about?
Iterating ((wisely: you are removing items) on all the ListView items you could use the Find[^] for getting the array of items matching the current one and, interating in turn on such array, remove the ones matching the subitem too.

[update 2]
Try (I've not tested it):
Dim i as Integer = 0

While (i < lstV_Result.Items.Count) 
      RemoveListViewLine(i, lstV_Result.Items(i).SubItems(1).Text, lstV_Result.Items(i).SubItems(9).Text)
      i = i + 1
End While


Private Sub RemoveListViewLine(ByVal n as Integer, ByVal TextCrit As String, ByVal SubCrit As String)
     Dim li As ListViewItem
     n = n + 1
     While (n < lstV_Result.Items.Count)
          li = lstV_Result.Items(n)
          If li.SubItems(1).Text = TextCrit And li.SubItems(9).Text = SubCrit Then
              lstV_Result.Items.Remove(li)
          Else
              n = n + 1
          End If
     End While
End Sub
