If you need to remove any number of whitespace characters from the string, probably you're looking for something like this:

value = Regex.Replace(value, @"\s+", "");

where \s matches any whitespace character and + means one or more times.

You may want to try \s indicating white spaces. With the statement Regex.Replace(value, @"\s", ""), the output will be "abcabcdabcd".

Instead of replacing your newline, tab, etc. characters with a space, just replace all whitespace with nothing:

public static string RemoveWhitespace(string value)
{
    return Regex.Replace(value, "\\s", "");
}

\s is a special character group that matches all whitespace characters. (The backslash is doubled because the backslash has a special meaning in C# strings as well.) The following MSDN link contains the exact definition of that character group:
