Tech IQ: How Well Do You Know Visual Basic.NET 2012?

I think the modern way is

Dim path = "\ProgramData\Backup\Backup" & ListBox1.Items.Count & ".txt"

IO.File.WriteAllLines(path, ListBox1.Items)

Er, does that work? If not:

Dim path = "\ProgramData\Backup\Backup" & ListBox1.Items.Count & ".txt"

IO.File.WriteLines(path, From x In ListBox1.Items Select x.ToString())

or even:

Dim path = "\ProgramData\Backup\Backup" & ListBox1.Items.Count & ".txt"
IO.File.WriteAllLines(path, ListBox1.Items.Cast(Of Object).Select(Function(o) ListBox1.GetItemText(o)).ToArray)
