All my code does is to replace back-space characters (ASCII 8) with hyphens. It doesn't change 'normal' space characters (ASCII 32) at all. Are you saying that you want to replace normal spaces within href only with hyphens? If so then it can be done using regular expressions as follows: using System.IO; using System.Text.RegularExpressions; // ... string html = File.ReadAllText(darma.htm); char[] chars = html.ToCharArray(); string regExp = @ ; MatchCollection mc = Regex.Matches(html regExp); foreach(Match m in mc) { int index = m.Groups[1].Index; int length = m.Groups[1].Length; for(int i = index; i { if(chars[i] == ' ') chars[i] = '-'; } } html = new string(chars); File.WriteAllText(darma.htm html);

Hi Vulpes Thank you very much for the reply. Actually when I did with this code It removes all black spaces in html file. But I want to remove only blank spaces in href only. Darma

It seems odd to have backspace characters (ASCII 8) in an HTML file but if that's what they are then you may be able to replace them all with hyphens using a simple string replace: using System.IO; // ... string html = File.ReadAllText(darma.htm); html = html.Replace('\b' '-'); File.WriteAllText(darma.htm html);
