客户端、服务器端中JSON字符串与对象的转换

客户端：

字符串转为对象：$.parseJSON(json);

对象转为字符串：JSON.stringify(_pasteDataItem)

服务器端(c#)：

对象：

 [DataContract(Namespace = "")]         public class SecurityRequest //: ServiceRequestBase         {             /// <summary>             /// Ctor - allocate the list             /// </summary>             public SecurityRequest()             {             }

            [DataMember]             public string RoleName { get; set; }

            [DataMember]             public string UserAccount { get; set; }

            [DataMember]             public bool IsMarkedForDelete { get; set; }

            [DataMember]             public bool IsOld { get; set; }         }

对象转为字符串：

PayloadBuilder.WriteObjToJson(userList);

    public static class PayloadBuilder
    {
        public static string WriteObjToJson(Object obj)
        {
            DataContractJsonSerializer js = new DataContractJsonSerializer(obj.GetType());
            string jsString = "";
            using (MemoryStream stream = new MemoryStream())
            {
                js.WriteObject(stream, obj);
                jsString = Encoding.UTF8.GetString(stream.ToArray());
            }
            return jsString;
        }
    }

字符串转为对象：
            var secList = (List<SecurityRequest>)DeserializeJsonString(security, typeof(List<SecurityRequest>));
        public static Object DeserializeJsonString(string jsonString, Type type)
        {
            using (var ms = new MemoryStream(Encoding.UTF8.GetBytes(jsonString)))
            {
                DataContractJsonSerializer js = new DataContractJsonSerializer(type);
                return js.ReadObject(ms);
            }
        }

 如是MVC中，会自动转，但仅限简单对象。
