Question

The string I am trying to clean looks like

"\r\nPasswordchanged?\r\r\n"    string

I used this method

public string[] cleanStrings(string[] clean)
    {
        int j = 0;
        foreach (string data in clean)
        {
            string temp = System.Text.RegularExpressions.Regex.Replace(data, @"\r\n+", "");
            if (temp.Equals(" "))
            {
                temp = "";
            }
            clean[j] = temp;
            j++;
        }
        return clean;
    }

The result was

"Passwordchanged?\r"    string

I thought my regex would remove all the \r and \n

Did I miss something?

Answer 1

Use a character class instead, specifically [\r\n]. This way any character in the character class will match.

string result = Regex.Replace(data, @"[\r\n]", "");

Your current pattern, \r\n+, will only match an \r followed by one or more \n characters, so it won’t be able to match other stand-alone \r characters for example.
