1.add reference [System.Runtime.Serializatio]
2.using [System.Runtime.Serialization] and [System.Runtime.Serialization.Json]
3.define model class add [DataContract] and [DataMember] attribute
class Demo{ ???[DataMember] ???public int ID { get; set; } ???[DataMember] ???public string Name { get; set; } ???[DataMember] ???public int Age { get; set; }}4.convert code
DataContractJsonSerializer jsonSer = new DataContractJsonSerializer(typeof(Demo)); ???????????//json to modelstring strJson = "{\"ID\":3,\"Name\":\"TestName\",\"Age\":100}";Stream ms1 = new MemoryStream(Encoding.Default.GetBytes(strJson));Demo item1 = (Demo)jsonSer.ReadObject(ms1);ms1.Close(); ???????????//model to jsonDemo item2 = new Demo { ID = 1, Name = "TestName", Age = 12 };Stream ms2 = new MemoryStream();jsonSer.WriteObject(ms2, item2);byte[] arr = new byte[ms2.Length];ms2.Position = 0;ms2.Read(arr, 0, arr.Length);ms2.Close();Console.WriteLine(Encoding.Default.GetString(arr));JSON序列化与反序列化
