Remove Whitespace

I added this method to the StringManip class in DCToolbox:

protected string RemoveWhiteSpace(string str)
        {
            if (str.Length > 0)
            {
                while (str.IndexOf(" ") > 0)
                {
                    str = Regex.Replace(str, " ", "");
                }
            }
            str = str.Trim();
            return str;
        }
