1.将json string转化成object
1: public static T GetObjectFromJson<T>(string jsonString)
2: {
3: DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(T));
4: MemoryStream stream = new MemoryStream(Encoding.UTF8.GetBytes(jsonString));
5: var obj = (T)serializer.ReadObject(stream);
6: stream.Close();
7: return obj;
8: }
2.将obect转化成json string
1: public static string GetJsonFromObject<T>(T obj)
2: {
3: DataContractJsonSerializer json = new DataContractJsonSerializer(typeof(T));
4: using (MemoryStream ms = new MemoryStream())
5: {
6: json.WriteObject(ms, obj);
7: string szJson = Encoding.UTF8.GetString(ms.ToArray());
8: return szJson;
9: }
10: }
注意，定义的对象T一定要和json 字符串一一对应
e.g: json string {\"ID\":1,\"Items\":[{\"Name\":\"22\"},{\"Name\":\"23\"}]}
定义的对象就必须是：
1: [DataContract]
2: class Demo
3: {
[DataMember]
4: public int ID { get; set; }
5: [DataMember]
6: public List<Student> Items { get; set; }
7: }
8:
9: [DataContract]
10: class Student
11: {
12: [DataMember]
13: public string Name { get; set; }
14: }
其中T就是Demo 这个类
使用：
1: string json = "{\"ID\":1,\"Items\":[{\"Name\":\"22\"},{\"Name\":\"23\"}]}";
2: Demo obj = GetObjectFromJson<Demo>(json);
