List files in ListBox without filepath in Visual Basic

Question

I'm trying to list files into a ListBox with

Dim files() As String = IO.Directory.GetFiles(CurDir, "*.txt")

For the ListBox I use

ListBox1.Items.AddRange(files)

But it returns with a full path, how would I be able to only get the filename?

There are multiple options. If you wanted to stick as closely as possible to what you already have, you can call Path.GetFileName for each file path, e.g.

Dim filePaths = Directory.GetFiles(CurDir, "*.txt")
Dim fileNames = Array.ConvertAll(filePaths, Function(s) Path.GetFileName(s))

ListBox1.Items.AddRange(fileNames)

I would go with a slightly different approach though. I'd suggest that you use DirectoryInfo, FileInfo and data-binding:

Dim folder = New DirectoryInfo(CurDir)
Dim files = folder.GetFiles("*.txt")

With ListBox1
    .DisplayMember = "Name"
    .ValueMember = "FullName"
    .DataSource = files
End With

The user will now see just the file names, but you can get the full path for the selected item from the SelectedValue property.
