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;
            }
