1、首先确保程序集中添加了 System.Web.Extensions DLL引用
2、代码中添加命名空间:using System.Web.Script.Serialization;
namespace JavescripSerializer { class Program { static void Main(string[] args) { JavaScriptSerializer Script = new JavaScriptSerializer(); User user = new User(); user.id = 1; user.UserName = "王文建"; user.Memo = "备注"; user.Tel.Add(new TelPhone() { Numer = "18363963258" }); user.Tel.Add(new TelPhone() { Numer = "18863936247" }); string result = Script.Serialize(user); //得到序列化json var User = Script.Deserialize<User>(result); //获得反序列化对象 } } /// <summary> /// 用户类 /// </summary> public class User { /// <summary> /// id /// </summary> public int id { get; set; } /// <summary> /// 用户名称 /// </summary> public string UserName { get; set; } /// <summary> /// 备注 /// </summary> public string Memo { get; set; } /// <summary> /// 电话号码-一个用户可以多个号码 /// </summary> public List<TelPhone> Tel { get; set; } public User() { Tel = new List<TelPhone>(); } } /// <summary> /// 电话类 /// </summary> public class TelPhone { /// <summary> /// 电话号码类 /// </summary> public string Numer { get; set; } } }
