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;

        }
