Question

I have a field that I use to hold text. I am going to hold the text in a HTML textarea but I need to set the number of lines.

How can I count the number of line feeds in a string so I can set the textarea rows?

Answer 1

A line break is one or two characters, depending on the system. On a windows system it’s the two character combination \r\n, but you can look for only one of them when counting them.

As a string is enumerable, you can use the Count extension method:

int cnt = str.Count(c => c == '\n');
