public:
 System::Object ^ Deserialize(System::String ^ input, Type ^ targetType);

public object Deserialize(string input, Type targetType);

member this.Deserialize : string * Type -> obj

Public Function Deserialize (input As String, targetType As Type) As Object

input 包含指示 Object 或不可实例化的类型（例如，抽象类型或接口）的“__type”属性。

- 或 -

尝试将 JSON 数组转换为类似数组的托管类型，该类型不可用作 JSON 反序列化目标。

- 或 -

不能将 input 转换为目标类型。

generic <typename T> T Deserialize(System::String ^ input);

public T Deserialize<T>(string input);

member this.Deserialize : string -> 'T

Public Function Deserialize(Of T) (input As String) As T

input 包含指示 Object 或不可实例化的类型（例如，抽象类型或接口）的“__type”属性。

- 或 -

尝试将 JSON 数组转换为类似数组的托管类型，该类型不可用作 JSON 反序列化目标。

- 或 -

不能将 input 转换为 T 。

以下示例提供了一个简单的说明，说明如何序列化和反序列化数据对象。

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
它需要名为 Person的类，如以下示例所示。
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
    	
方法 Deserialize 等效于首先使用 DeserializeObject 方法获取对象图，然后尝试将结果强制转换为类型 T。
在反序列化期间，将引用序列化程序的当前类型解析程序，从而确定在转换嵌套在数组和字典类型中的元素时要使用的托管类型。 因此，反序列化过程会循环访问 的所有嵌套元素 input。 有关类型解析程序的详细信息，请参阅 JavaScriptTypeResolver 类。
