public static string Replace(string oldStr)
        {
            if (string.IsNullOrEmpty(oldStr))
            {
                return \"\";
            }
            string str2 = Regex.Replace(oldStr, @\"[\\[\\+\\\\\\|\\(\\)\\^\\*\\\"\"\\]\'%~#-&]\", delegate(Match match)
            {
                if (match.Value == \"\'\")
                {
                    return \"\'\'\";
                }
                else
                {
                    return \"[\" + match.Value + \"]\";
                }
            });
            return str2;
