How to remove spaces and newlines in a string

Question

sorry if they are not very practical for C # Asp.Net, I hope to make me understand I have this situation

string content = ClearHTMLTags(HttpUtility.HtmlDecode(e.Body));
content=content.Replace("\r\n", "");
content=content.Trim();
((Post)sender).Description = content + "...";

I would make sure that the string does not contain content nor spaces (Trim) and neither carriage return with line feed, I'm using the above code inserted but it does not work great either

any suggestions??

Thank you very much Fabry

Explain "does not work great", show example input and output. — CodeCaster, Jan 09 '14 at 10:24

You can remove all whitespaces with this regex

content = Regex.Replace(content, @"\s+", string.Empty);

what are whitespace characters from MSDN.

Btw you are mistaking Trim with removing spaces, in fact it's only removing spaces at the begining and at the end of string. If you want to replace all spaces and carige returns use my regex.

this should do it

String text = @"hdjhsjhsdcj/sjksdc\t\r\n asdf";

        string[] charactersToReplace = new string[] { @"\t", @"\n", @"\r", " " };
        foreach (string s in charactersToReplace)
        {
            text = text.Replace(s, "");
        }

simple change only you missed @ symbol

string content = ClearHTMLTags(HttpUtility.HtmlDecode(e.Body));
content=content.Replace(@"\r\n", "");
content=content.Trim();
((Post)sender).Description = content + "...";
