Windows Phone - First line of TextBox

Question

I've founded the following code to take the first line from a string:

string firstline = test.Substring(0, test.IndexOf(Environment.NewLine));

This does not work because the XAML TextBox uses a \r to represent a linebreak, but Environment.NewLine is \r\n.

Is there a defined constant string for NewLine in WindowsPhone/XAML?

Answer 1

Try splitting on "\r", I found an example in the answer here.

Hope this helps!

Answer 2

Your code is fine. Did you set MultiLine property to true?

Environment.NewLine defines
A string containing "\r\n" for non-Unix platforms, or a string containing "\n" for Unix platforms.

Hope it helps.
