JavaScriptSerializer 类

原文链接：https://learn.microsoft.com/zh-cn/dotnet/api/system.web.script.serialization.javascriptserializer?view=netframework-4.8.1&redirectedfrom=MSDN

命名空间:
System.Web.Script.Serialization
程序集:
System.Web.Extensions.dll

对于 .NET Framework 4.7.2 及更高版本，请使用 命名空间中的 System.Text.Json API 进行序列化和反序列化。 对于早期版本的 .NET Framework，请使用 Newtonsoft.Json。 此类型旨在为已启用 AJAX 的应用程序提供序列化和反序列化功能。

继承

public class JavaScriptSerializer

示例

第一个示例简单演示了如何序列化和反序列化数据对象。 它需要名为 Person 的类，如下所示。

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

namespace ExampleApplication
{
    public partial class _Default : Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            var RegisteredUsers = new List<Person>();
            RegisteredUsers.Add(new Person() { PersonID = 1, Name = "Bryon Hetrick", Registered = true });
            RegisteredUsers.Add(new Person() { PersonID = 2, Name = "Nicole Wilcox", Registered = true });
            RegisteredUsers.Add(new Person() { PersonID = 3, Name = "Adrian Martinson", Registered = false });
            RegisteredUsers.Add(new Person() { PersonID = 4, Name = "Nora Osborn", Registered = false });

            var serializer = new JavaScriptSerializer();
            var serializedResult = serializer.Serialize(RegisteredUsers);
            // Produces string value of:
            // [
            //     {"PersonID":1,"Name":"Bryon Hetrick","Registered":true},
            //     {"PersonID":2,"Name":"Nicole Wilcox","Registered":true},
            //     {"PersonID":3,"Name":"Adrian Martinson","Registered":false},
            //     {"PersonID":4,"Name":"Nora Osborn","Registered":false}
            // ]

            var deserializedResult = serializer.Deserialize<List<Person>>(serializedResult);
            // Produces List with 4 Person objects
        }
    }
}

namespace ExampleApplication
{
    public class Person
    {
        public int PersonID { get; set; }
        public string Name { get; set; }
        public bool Registered { get; set; }
    }
}
