Question : count total lines or "returns" from a string of text

I have a string of text retrieve from the database which i retrieve and populate a textbox.
Issue:
Me.TextBox.Text = list -A -B -C 'String of text from database'

I need to count how many "returns"(new lines) does the string of text contain so i can then do something like
Me.TextBox.Rows = Line of text

so in my textbox i will see just how the user types it.
-A
-B
-C.

Thanks!
