Answer 1

You can try with this code

var input = "-hello World 1 -hello World 2";
var result = input.Replace("-",Environment.NewLine + "-" );

Answer 2

Its because when you entered the data in text area. It generates \\n or \\r for new line. And in terms of html it doesn't break the line. So the solution is replace these characters with
tag.

for example in the bind expression use this :

<%# Convert.ToString(Eval("Content")).Replace("\n","<br />").Replace("\r","<br />") %>

Hope this will help!

I don't know of any ready made way to do this. So just convert newlines to <br> tags and make other needed changes manually.

Or you can do something a little more fancy by converting newlines into new HTML paragraphs like I did in my article Converting Text to HTML .
