C#实现的json序列化和反序列化代码实例

using System;

namespace WebApplication1
{
 
//方法一：引入System.Web.Script.Serialization命名空间使用 JavaScriptSerializer类实现简单的序列化
[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; }
}
}
 
//方法二：引入 System.Runtime.Serialization.Json命名空间使用 DataContractJsonSerializer类实现序列化
//可以使用IgnoreDataMember:指定该成员不是数据协定的一部分且没有进行序列化，DataMember:定义序列化属性参数，使用DataMember属性标记字段必须使用DataContract标记类 否则DataMember标记不起作用。
[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; }
 
}

listperson.Add(p1);
listperson.Add(p2);
 
JavaScriptSerializer js = new JavaScriptSerializer();
//json序列化
string s = js.Serialize(listperson);
Response.Write(s);
 
 
 
//方法二
Person1 p11 = new Person1();
p11.Id = 1;
p11.Name = "hello";
p11.Sex = "男";
DataContractJsonSerializer json = new DataContractJsonSerializer(p11.GetType());

//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);
