推荐答案

看看这种方法：

Look at this approach:

Dim playList As New ArrayList
Dim openFileDialog1 As New OpenFileDialog()
openFileDialog1.Multiselect = true
Dim dr As DialogResult = OpenFileDialog1.ShowDialog()
If (dr = System.Windows.Forms.DialogResult.OK) Then
        playList.AddRange((From x in OpenFileDialog1.FileNames select Path.GetFileName(x)).ToArray())
        playList.Dump()
End If

感谢您的帮助，但我解决了我自己

Thanks for the help but i solved it my self

If OpenFileDialog1.ShowDialog(Me) = DialogResult.OK Then
           playList.Clear()
           playList.AddRange(OpenFileDialog1.FileNames)
           'SaveArrayList("C:\playlist.txt", playList)
           For Each File In playList
               '        ' objItem.myplaylist.Items.Add(File)
               objItem = myplaylist.Items.Add(My.Computer.FileSystem.GetFileInfo(File).Name)
               '        objItem = myplaylist.Items.Add(File)
               objItem.SubItems.Add((New FileInfo(File).Length / 1000).ToString("f2") + " " + "KB")
           Next
       End If
