What is the exact output you get from your code? It should replace the newlines fine. — DavidG, Jun 25 '18 at 14:55
Try using `.Replace(" ", " ")` where the first string is 2 spaces and the second is 1. — itsme86, Jun 25 '18 at 14:57
If s is the text, use Regex.Replace(Regex.Replace(s, "[ ]{2,}", " ", RegexOptions.Multiline), "\r|\n", "", RegexOptions.Multiline); — user1515791, Jun 25 '18 at 14:58
`string result = Regex.Replace(original.Replace(",", ", "), @"\s{2,}", " ").Replace(" ,", ",");` — Dmitry Bychenko, Jun 25 '18 at 15:02

Well, you replaced all blanks by nothing ( .Replace(" ", "") ). What did you expect? Now all your blanks are gone.

If you don't want that, don't do it.

You could try to `Split` your string, then trim each line and then concatenate them. – nvoigt Jun 25 '18 at 14:56

you can try like this, by splitting and trimming the string to remove spaces and join them back by newline

var address = dd[i].InnerText.Split(new[] { Environment.NewLine })
                    .Select(s => s.Trim());    
info.Address = String.Join(Environment.NewLine, address);

You're assuming the source text is using `Environment.NewLine` and doesn't come from another source that could be anything. – DavidG Jun 25 '18 at 14:59
@DavidG, hmm thought so – Rahul Jun 25 '18 at 15:01

I mean, it's probably fine, but I think the dupe covers the answers more comprehensively. – DavidG Jun 25 '18 at 15:02
