[C#] JSON 序列化及反序列化 筆記

今天有使用到 先作個 Demo 筆記

下記範例下載

1.) 需要加入參考
System.ServiceModel.Web
System.Runtime.Serialization

2.) 先建立對象
 public class Pz
    {
        public string EMP_ID { get; set; }
        public string NAME { get; set; }
        public int Age { get; set; }
    }

3.) 做序列化
            Pz Q = new Pz();
            Q.Age = 10;
            Q.EMP_ID = "12345";
            Q.NAME = "king";
            DataContractJsonSerializer ds = new DataContractJsonSerializer(typeof(Pz));
            using (MemoryStream ms = new MemoryStream())
            {
                ds.WriteObject(ms, Q);
                output = Encoding.UTF8.GetString(ms.ToArray());
                MessageBox.Show("這是序列化：" + output);
            }

           
4.) 反序列化
             if (output.Length == 0)
            {
                return;
            }
            DataContractJsonSerializer outDs = new DataContractJsonSerializer(typeof(Pz));
            using (MemoryStream outMs = new MemoryStream(Encoding.UTF8.GetBytes(output)))
            {
                Pz QQ = outDs.ReadObject(outMs) as Pz;
                MessageBox.Show(QQ.Age + "," + QQ.EMP_ID + "," + QQ.NAME);
            }
