如何确定列表框中的多个字符串？

这似乎是一个简单的问题，但我的方式似乎冻结我的程序没有错误。 我想确定是否一个字符串被添加到我的列表框中的子项目，如果是这样就删除它.. 这里是我试图使用的代码

This may seem to be a simple question but the way I am going about it seems to freeze my program with no error. I am looking to determine if a string is being added to a subitem in my listbox and if so to remove it.. here is the code I am trying to use

Dim hiber As String = "hiberfil.sys" Dim FXSAPI As String = "FXSAPIDebugLogFile.txt" Dim setup1 As String = "setup-a.bin" Dim setup2 As String = "setup-b.bin" For Each ListViewItem As ListViewItem In resultsbox.Items If ListViewItem.SubItems(1).Text = hiber or FXSAPI or setup1 or setup2 Then ListViewItem.Remove() End If Next

我可以用其他方式实现这个目标吗？... 提前谢谢

what other way can i achieve this?.. thank you in advance

推荐答案

你的if语句被严重搞砸了。你不能列出一个项目列表（你正在他们！）来比较一个变量。您必须单独将变量与列表中的每个项目进行比较。 （顺便说一句：你的ListViewItem变量名是一个可怕的选择，因为它与一个知名类的名称完全相同。只需称它为 item 并完成它。） Your if statement is seriously screwed. You cannot make a list of items (you''re OR''ing them!) to compare a single variable to. You MUST compare the variable to each item in the list seperately. (BTW: Your ListViewItem variable name is a TERRIBLE choice since it''s exactly the same as the name of a well-known class. Just call it item and be done with it.) If ListViewItem.SubItems(1).Text = hiber or FXAPI or ...

成为

becomes

Dim subItem As String = ListViewItem.SubItems(1).Text If subItem = hiber Or subItem = FXSAPI Or subitem = setup1 Or subItem = setup2 Then ...

这是一个VB.NET（或任何其他语言）101件事。你真的需要在VB.NET上学习一本初学者书并完成它。

This is a VB.NET (or any other language) 101 thing. You REALLY need to pickup a beginners book on VB.NET and work through it.
