/// <summary>
        /// 处理json字符串，将[]{}'"字符去除
        /// </summary>
        /// <param name="JsonStr">需处理的字符串</param>
        /// <returns>处理后的字符串</returns>
        public static string DealJsonStr(string JsonStr)
        {
            Regex regex = new Regex(@"[\]\[\}\{""\']+");
            Match match = null;
            while ((match = regex.Match(JsonStr)).Success)
            {
                JsonStr = JsonStr.Replace(match.Value, string.Empty);
            }
            return JsonStr;
