How to Loop through Listview items
提问by user1532468
I need some kind of loop, I think, to put into a variable for inclusion in access db. The problem I have at the minute is that with the code I am using, it gets the first value and if I click on another item, it retains the old value and dosen't update with new value.
我认为我需要某种循环来放入一个变量以包含在访问数据库中。我目前遇到的问题是，使用我正在使用的代码，它会获取第一个值，如果我单击另一个项目，它会保留旧值并且不会使用新值更新。
How can I create a loop that will store the values from selected items. Thanks
如何创建一个循环来存储所选项目的值。谢谢
With lvSelectedItems.Items
Dim username As String = .Item(0).Text
Dim session As String = .Item(0).SubItems.Item(1).Text
output = username + " : " + session
MessageBox.Show(output)
End With

The code I supplied just gets the first valuebecause you only looked at one item over and over:
The code I supplied just gets the first value因为你只看了一遍又一遍：
Dim username As String
Dim session As String
For Each item As ListViewItem In Me.lvSelectedItems.Items
username = Item.Text
session = Item.SubItems.Item(1).Text
output = username + " : " + session
console.WriteLine(output) ' show results of this loop iteration
Next
This will process all the items in lvselecteditemswhich is a very confusing name. To process just the selected items use
这将处理lvselecteditems名称非常混乱的所有项目。要仅处理选定的项目，请使用
For Each item As ListViewItem In Me.lvSelectedItems.SelectedItems
