将Dictionary序列化为json数据 、json数据反序列化为Dictionary

需要引用System.Web.Extensions  dll类库

/// <summary>
        /// 将json数据反序列化为Dictionary
        /// </summary>
        /// <param name="jsonData">json数据</param>
        /// <returns></returns>
        private Dictionary<string, object> JsonToDictionary(string jsonData)
        {
            //实例化JavaScriptSerializer类的新实例
            JavaScriptSerializer jss = new JavaScriptSerializer();
            try
            {
                //将指定的 JSON 字符串转换为 Dictionary<string, object> 类型的对象
                return jss.Deserialize<Dictionary<string, object>>(jsonData);
            }
            catch (Exception ex)
            {
                throw new Exception(ex.Message);
            }
        }
        /// <summary>
        /// 将Dictionary序列化为json数据
        /// </summary>
        /// <param name="jsonData">json数据</param>
        /// <returns></returns>
        private string DictionaryToJson(Dictionary<string, object> dic)
        {
            //实例化JavaScriptSerializer类的新实例
            JavaScriptSerializer jss = new JavaScriptSerializer();
            try
            {
                //将指定的 JSON 字符串转换为 Dictionary<string, object> 类型的对象
                return jss.Serialize(dic);
            }
            catch (Exception ex)
            {
                throw new Exception(ex.Message);
            }
        }

List集合序列化可使用：

 /// <summary>
        /// JSON序列化
        /// </summary>
        public string JsonSerializer<T>(T t)
        {
            DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(T));
            MemoryStream ms = new MemoryStream();
            ser.WriteObject(ms, t);
            string jsonString = Encoding.UTF8.GetString(ms.ToArray());
            ms.Close();
            return jsonString;
        }
