I have a richtextbox, actually a mmRichTextBox.

I want to determine which line has a value.

Things i know :
It has a array that is called lines and i can get each line.
I am loopiong through each line now.

How do i determine if the line is just a carriage return or it has text and a carriage return. I can tell by the length but this is un reliable, as a letter 't' will be the same length as just a carriage return.

I have tried compareto, endswith, but to no avail, does it return the right bool or int value.

Thanks!
