JavaScriptSerializer 类

定义

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 System.Text.Json 命名空间中的 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。

public ref class JavaScriptSerializer
public class JavaScriptSerializer
type JavaScriptSerializer = class
Public Class JavaScriptSerializer
继承
Object
JavaScriptSerializer

示例

第一个示例简单说明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
        }
    }
}

Imports System.Web.Script.Serialization

Public Class _Default
    Inherits Page

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load
        Dim RegisteredUsers As New List(Of Person)()
        RegisteredUsers.Add(New Person With {.PersonID = 1, .Name = "Bryon Hetrick", .Registered = True})
        RegisteredUsers.Add(New Person With {.PersonID = 2, .Name = "Nicole Wilcox", .Registered = True})
        RegisteredUsers.Add(New Person With {.PersonID = 3, .Name = "Adrian Martinson", .Registered = False})
        RegisteredUsers.Add(New Person With {.PersonID = 4, .Name = "Nora Osborn", .Registered = False})

        Dim serializer As New JavaScriptSerializer()
        Dim 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}
        ' ]

        Dim deserializedResult = serializer.Deserialize(Of List(Of Person))(serializedResult)
        ' Produces List with 4 Person objects
    End Sub
End Class

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

Public Class Person
    Public Property PersonID As Integer
    Public Property Name As String
    Public Property Registered As Boolean
End Class

下一个示例演示了一个更复杂的完整项目，该项目 JavaScriptSerializer 使用类通过 JSON 序列化保存和还原对象的状态。 此代码使用为 JavaScriptConverter 类提供的自定义转换器。

注解

Important

对于 .NET Framework 4.7.2 及更高版本，System.Text.Json 命名空间中的 API 应用于序列化和反序列化。 对于早期版本的 .NET Framework，请使用 Newtonsoft.Json。

异步 JavaScriptSerializer 通信层在内部使用该类来序列化和反序列化浏览器和 Web 服务器之间传递的数据。 无法访问序列化程序的实例。 但是，此类公开公共 API。 因此，在托管代码中使用 JavaScript 对象表示法（JSON）时，可以使用该类。

若要序列化对象，请使用 Serialize 该方法。 若要反序列化 JSON 字符串，请使用 Deserialize 或 DeserializeObject 方法。 若要序列化和反序列化不受本机支持 JavaScriptSerializer的类型，请使用 JavaScriptConverter 该类实现自定义转换器。 然后使用该方法注册转换器 RegisterConverters 。

托管类型和 JSON 之间的映射

下表显示了序列化过程的托管类型和 JSON 之间的映射。 这些托管类型本机受支持 JavaScriptSerializer。 从 JSON 字符串反序列化为托管类型时，将应用相同的映射。 但是，反序列化可以是非对称的;并非所有可序列化的托管类型都可以从 JSON 反序列化。

Note

多维数组序列化为一维数组，应将其用作平面数组。

托管类型 JSON 等效项
String （仅限 UTF-8 编码）。 String
Char String
单个 null 字符（如 \0） Null
Boolean 布尔值。 以 JSON 表示为 true 或 false
null （null 对象引用和 Nullable 值类型）。 null 的字符串值
DBNull null 的字符串值
基元数值（或与数值兼容的）类型： Byte、、 SByte、 Int16、 Int32、、 Int64、 UInt16、 UInt32、 UInt64、 Double和 Single。 使用区域性固定字符串表示形式。 编号
DateTime 日期对象，用 JSON 表示为“\/Date（时钟周期数）\/”。 时钟周期数是正值或负长值，指示自 1970 年 1 月 1 日午夜以来经过的时钟周期数（毫秒）。

支持的最大日期值为 MaxValue （12/31/9999 11：59：59 PM），支持的最小日期值为 MinValue （1/1/0001 12：00：00 AM）。
整数类型的枚举 枚举值的整数等效项
实现IEnumerable或不是或不是实现的类型System.Collections.Generic.IDictionary<TKey,TValue>IDictionary。System.Collections.Generic.IEnumerable<T> 这包括类型，例如 Array， ArrayList和 List<T>。 使用 JSON 数组语法的数组
实现 IDictionary 或 System.Collections.Generic.IDictionary<TKey,TValue>. 这包括类型，例如 Dictionary<TKey,TValue> 和 Hashtable。 使用 JSON 字典语法的 JavaScript 对象
具有具有获取访问器或公共实例字段的公共实例属性的自定义具体（非抽象）类型。

请注意，这些类型中标有 ScriptIgnoreAttribute公共写入属性、公共属性或公共字段属性以及公共索引属性将被忽略。		 使用 JSON 字典语法的 JavaScript 对象。 包含一个名为“__type”的特殊元数据属性，以确保正确的反序列化。 确保公共实例属性具有获取和设置访问器，以确保正确的反序列化。
Guid GUID 的字符串表示形式
Uri 返回值的字符串表示形式 GetComponents
