vb.net - ListView 与 FTP VB.net

Question

我想在 ListView 上显示我的 FTP 服务器上的目录和文件。我是 ListViews 的新手，所以有人可以帮我开始吗？

代码：

Dim newSelected As TreeNode = e.Node
        ListView1.Items.Clear()
        Dim nodeDirInfo As DirectoryInfo = _
        CType(newSelected.Tag, DirectoryInfo)
        Dim subItems() As ListViewItem.ListViewSubItem
        Dim item As ListViewItem = Nothing

        Dim dir As DirectoryInfo
        For Each dir In nodeDirInfo.GetDirectories()
            item = New ListViewItem(dir.Name, 0)
            subItems = New ListViewItem.ListViewSubItem() _
                {New ListViewItem.ListViewSubItem(item, "Directory"), _
                New ListViewItem.ListViewSubItem(item, _
                dir.LastAccessTime.ToShortDateString())}

            item.SubItems.AddRange(subItems)
            ListView1.Items.Add(item)
        Next dir
        Dim file As FileInfo
        For Each file In nodeDirInfo.GetFiles()
            item = New ListViewItem(file.Name, 1)
            subItems = New ListViewItem.ListViewSubItem() _
                {New ListViewItem.ListViewSubItem(item, "File"), _
                New ListViewItem.ListViewSubItem(item, _
                file.LastAccessTime.ToShortDateString())}

            item.SubItems.AddRange(subItems)
            ListView1.Items.Add(item)
        Next file

Answer 1

如果没有目录被添加到 Listview，很可能是因为它nodeDirInfo.GetDirectories是空的。设置断点并检查其内容。它可能与 ListView 本身无关。路径 NewSelected.Tag 中是否有任何子目录？
