DataContractJsonSerializer的序列化与反序列化

..
using System.Runtime.Serialization.Json;(要添加 System.ServiceModel.Web引用)
 
实体类
YunQiData model = new YunQiData();
model.AddDate = DateTime.Now.ToString();
model.Amount = 100;
model.PPlatformID = 100;
model.SID = 100;
model.UID = "2";序列化与化序列化
DataContractJsonSerializer ds = new DataContractJsonSerializer(typeof(YunQiData)); 
using (MemoryStream ms = new MemoryStream())
{ 
                ds.WriteObject(ms, model);
                string output = Encoding.UTF8.GetString(ms.ToArray()); 
                Console.WriteLine(output);                var ser = new DataContractJsonSerializer(typeof(YunQiData));
                var ms2 = new MemoryStream(Encoding.UTF8.GetBytes(output));
                YunQiData myClass1 = (YunQiData)ser.ReadObject(ms2);
                if (myClass1 != null)
                {                      //doing
                }
            }
