TextBox # of lines without API?

Is there a way to find out the total number of used lines in a TextBox in VB.NET without using API?

-- Ethan --

this would does the trick

VB Code:

Dim ar() As String
ar = TextBox1.Lines
MsgBox(ar.Length())

by the way , when you hit enter and leave out an empty line is considered 1 line.

i think yes
