Environment.Newline Vs. ControlChars.Newline?

[yoda]

Quick Question, in class today we were learning something to do with newlines, but the teacher didn't explain the difference between Environment.new line and ControlChars.ne wline, she was wondering as well because the text book uses Environment and she's always used ControlChars.

Can some one possibly explain the difference between the two? And When you would use one or the other?

Thanks,

Yoda.
