Several lines to textArea on runtime - aspx

Hello,
I would like to set the textArea on runtime,
but i need set more then one line.
How can I do that ?
I did :

ta.value = "ab\r\ncd"
....
and it works fine.

, but I did the same on vbscript run on aspx (asp dotnet),
but I see the \r\n in the text.
Something like this :
....
dim curr_area
curr_area = new htmlTextArea()
curr_area.rows = 10
curr_area.cols = 20
curr_area.value = "line1" & "\r\n" & "line2"
....

What is the problem in my code.
