using System;
using System.Collections.Generic;
using System.Web.Script.Serialization;

using System.IO;
using System.Text;


namespace WebApplication1
{

  //辦法一：引入System.Web.Script.Serialization定名空間應用 JavaScriptSerializer類完成簡略的序列化
  [Serializable]
  public class Person
  {
    
    private int id;
    /// <summary>
    /// id
    /// </summary>
    public int Id
    {
      get { return id; }
      set { id = value; }
    }

    private string name;
    /// <summary>
    /// 姓名
    /// </summary>
    public string Name
    {
      get { return name; }
      set { name = value; }
    }
  }

  //辦法二：引入 System.Runtime.Serialization.Json定名空間應用 DataContractJsonSerializer類完成序列化
  //可使用IgnoreDataMember:指定該成員不是數據協議的一部門且沒有停止序列化，DataMember:界說序列化屬性參數，應用DataMember屬性標志字段必需應用DataContract標志類 不然DataMember標志不起感化。
  [DataContract]
  public class Person1
  {
    
    [IgnoreDataMember]
    public int Id { get; set; }

    [DataMember(Name = "name")]
    public string Name { get; set; }
    [DataMember(Name = "sex")]
    public string Sex { get; set; }

  }

  public partial class _Default : System.Web.UI.Page
  {
    string constr = ConfigurationManager.ConnectionStrings["connstr"].ConnectionString;
    
    protected void Page_Load(object sender, EventArgs e)
    {
      
      Person p1 = new Person();
      p1.Id = 1;
      p1.Name = "dxw";
      Person p2 = new Person();
      p2.Id = 2;
      p2.Name = "wn";

      List<Person> listperson = new List<Person>();
      listperson.Add(p1);
      listperson.Add(p2);

      JavaScriptSerializer js = new JavaScriptSerializer();
      //json序列化
      string s = js.Serialize(listperson);
      Response.Write(s);



      //辦法二
      Person1 p11 = new Person1();
      p11.Id = 1;
      p11.Name = "hello";
      p11.Sex = "男";
      DataContractJsonSerializer json = new DataContractJsonSerializer(p11.GetType());

      string szJson = "";

      //序列化

      using (MemoryStream stream = new MemoryStream())

      {

        json.WriteObject(stream, p11);

        szJson = Encoding.UTF8.GetString(stream.ToArray());

        Response.Write(szJson);
      }

      //反序列化

      //using (MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(szJson)))

      //{

      //  DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(People));

      //  Person1 _people = (Person1)serializer.ReadObject(ms);

      //}
     }
    


    protected void Button1_Click(object sender, EventArgs e)
    {
