display music file

[meodihia]

I want to display music file (extension .wma ,.mp3 , .avi, etc..)
But I dont know how to display with a lot of extension
This is my code:

Private Sub TreeView1_NodeMouseDoubleClick(ByVal sender As Object, ByVal e As System.Windows.Forms.TreeNodeMouseClickEventArgs) Handles TreeView1.NodeMouseDoubleClick
        Dim catchNode As String
        catchNode = TreeView1.GetNodeAt(e.X, e.Y).FullPath
        Dim di As New IO.DirectoryInfo("E:\Music\" & catchNode)
        ListBox1.DataSource = di.GetFiles("*.mp3", IO.SearchOption.AllDirectories)
    End Sub

It's only display file extension .mp3 in ListBox1, but I want display more file extension
Can you help me?
Thanks for advanced!

If you want to get multiple extensions then you have to call GetFiles multiple times. Just create a List(Of FileInfo) and call AddRange each time to add the files with each extension. Once you've added all the files you can bind the List to your ListBox.

Or call getfiles once and scan the list yourself, looking at all the extensions
