//Remove scripts
str = Regex.Replace(str, "`<script.*?>`.*?`</script>`", "", RegexOptions.Singleline);  

//Remove CSS styles, if any found
str = Regex.Replace(str, "`<style.*?>`(.| )*?`</style>`", "", RegexOptions.Singleline);

//Remove all HTML tags, leaving on the text inside.
str= Regex.Replace(str, "`<(.| )*?>`", "", RegexOptions.Singleline);

//Remove \r,\t,\n
str= str.Replace("\r", "").Replace("\n", "").Replace("\t", "");

The following regex can be used to remove the style tag from the Html code.

System.Text.RegularExpressions.Regex.Replace(HtmlData,
                     @"(<style[^*]*</style>)","",
                     System.Text.RegularExpressions.RegexOptions.IgnoreCase);

Check the above code and let me know whether it is fine for you.

Why the [^*]? The asterisk is no special character in html. Do you perhaps mean <style[^>]*>?

@shivakant: str = Regex.Replace(str, "<script.*?>.*?</script>", "", RegexOptions.Singleline); this works fine
