后端开发-C#.Net教程1.首先是声明用户信息对象，DataContract修饰类，表示可以被解析成JSON，DataMember修饰属性，Order表示 解析的顺序，另外Lover是数组列表，表示女朋友个数

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Runtime.Serialization;namespace FunctionTest.Model{ [DataContract] public class UserInfo { [DataMember(Order =0)] public string UserName { get; set; } [DataMember(Order = 1)] public int Age { get; set; } [DataMember(Order = 2)] public int Gender { get; set; } [DataMember(Order =3)] public List Lover { get; set; } [DataMember(Order = 4)] public ContactAddress Address { get; set; } [DataMember(Order = 5)] public Dictionary DailyRecord {get; set; } } [DataContract] public class ContactAddress { [DataMember(Order =0)] public string Province { get; set; } [DataMember(Order = 1)] public string City { get; set; } [DataMember(Order = 2)] public string Country { get; set; } [DataMember(Order = 3)] public string Details { get; set; } }}
2.JSON帮助类 核心代码
/// /// /// /// public static T JsonToObject(string jsonText){ DataContractJsonSerializer s = new DataContractJsonSerializer(typeof(T)); MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(jsonText)); T obj = (T)s.ReadObject(ms); ms.Dispose(); return obj;}/// /// /// /// public static string ObjectToJSON(T obj){ DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(T)); string result = string.Empty; using (MemoryStream ms = new MemoryStream()) { serializer.WriteObject(ms, obj); ms.Position = 0; using (StreamReader read = new StreamReader(ms)) {result = read.ReadToEnd(); } } return result;}
3.调用
//1.对象-->JSONUserInfo info = new UserInfo{ Age = 10, Gender = 1, UserName = "刘德华", Lover = new List { "美女1", "美女2", "美女3" }, Address = new ContactAddress {Province = "湖南省",City = "长沙市",Country = "望城县",Details = "某旮旯快递找不到的地方" }, DailyRecord = new Dictionary { { "星期一", "吃饭" }, { "星期二", "洗衣服" }, { "星期三", "好事情" } }};string json = ObjectToJSON(info);
4.反序列化后的结果
代码如下:
{"UserName":"刘德华","Age":10,"Gender":1,"Lover":["美女1","美女2","美女3"],"Address":{"Province":"湖南省","City":"长沙市","Country":"望城县","Details":"某旮旯快递找不到的地方"},"DailyRecord":[{"Key":"星期一","Value":"吃饭"},{"Key":"星期二","Value":"洗衣服"},{"Key":"星期三","Value":"好事情"}]}
