AvalonEdit.Texeditor how to retirve an array of lines

good morning all.

there's anyone that know how to retrive from this.TextEditor.Text an array of lines.

e.g.:

this is the text
1: line one

2: line two

3: line

4: l

And I want to retrive an array like this:

String[ lines =  Avalon.textEditor.GetLines;

thanks in advance
