问题描述

我有一个列表视图代码，该代码将从0列中提取数字，然后按顺序将其删除.我遇到的问题是，一旦我删除了第一个，所有数字都是不同的，因为删除2、3变成2.我需要帮助，从列表视图中选择的最高数字开始到最低.现在，下面的代码以最低的编号开头.

I have a list view code that will take the numbers from column 0 and then in order delete them. the issue im having is once i delete the first one all the numbers are different becasue when you delete 2, 3 becomes 2. I need help starting from the highest number selected in the listview to the loest. right now the following code below starts with the lowest number.

Private Sub EditHeapToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles EditHeapToolStripMenuItem.Click

       Dim strObject As String = "C:\Temp\ASERVICE.EDM"

       For Each sitem As ListViewItem In Radia_Listview.SelectedItems
                      AZDelete(sitem.Text)
       Next

   End Sub

所以上面的代码给出并输出以下内容:
12345

我需要从
开始 54321

so the above code gives and output of:
12345

and i need it to start with
54321

推荐答案

从Radia_Listview.Items.Count循环到0，然后执行i-并将其删除.

Do a loop from Radia_Listview.Items.Count to 0 doing i-- and delete them that way.
