c# javascriptserializer能處理復雜對象嗎

是的，C# 的 JavaScriptSerializer 類可以處理復雜對象。它可以序列化和反序列化各種類型的對象，包括自定義類、集合、字典等。但是，需要注意的是，JavaScriptSerializer 類已經過時，不再建議使用。作為替代方案，你可以使用 JsonConvert 類，它是 Newtonsoft.Json 庫的一部分，功能更強大，而且更易于使用。

以下是一個使用 JavaScriptSerializer 處理復雜對象的示例：

using System;
using System.Web.Script.Serialization;

public class Person
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public Address Address { get; set; }
}

public class Address
{
    public string Street { get; set; }
    public string City { get; set; }
    public string State { get; set; }
    public string ZipCode { get; set; }
}

class Program
{
    static void Main()
    {
        Person person = new Person
        {
            FirstName = "John",
            LastName = "Doe",
            Address = new Address
            {
                Street = "123 Main St",
                City = "Anytown",
                State = "CA",
                ZipCode = "12345"
            }
        };

        JavaScriptSerializer serializer = new JavaScriptSerializer();
        string json = serializer.Serialize(person);
        Console.WriteLine(json);

        Person deserializedPerson = serializer.Deserialize<Person>(json);
        Console.WriteLine($"FirstName: {deserializedPerson.FirstName}, LastName: {deserializedPerson.LastName}, Address: {deserializedPerson.Address.Street}, {deserializedPerson.Address.City}, {deserializedPerson.Address.State}, {deserializedPerson.Address.ZipCode}");
    }
}

如果你想使用 JsonConvert，首先需要安裝 Newtonsoft.Json 庫。你可以通過 NuGet 包管理器安裝它，或者通過以下命令行安裝：

dotnet add package Newtonsoft.Json

然后，你可以使用以下代碼序列化和反序列化復雜對象：

using System;
using Newtonsoft.Json;

public class Person
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public Address Address { get; set; }
}

public class Address
{
    public string Street { get; set; }
    public string City { get; set; }
    public string State { get; set; }
    public string ZipCode { get; set; }
}

class Program
{
    static void Main()
    {
        Person person = new Person
        {
            FirstName = "John",
            LastName = "Doe",
            Address = new Address
            {
                Street = "123 Main St",
                City = "Anytown",
                State = "CA",
                ZipCode = "12345"
            }
        };

        string json = JsonConvert.SerializeObject(person);
        Console.WriteLine(json);

        Person deserializedPerson = JsonConvert.DeserializeObject<Person>(json);
        Console.WriteLine($"FirstName: {deserializedPerson.FirstName}, LastName: {deserializedPerson.LastName}, Address: {deserializedPerson.Address.Street}, {deserializedPerson.Address.City}, {deserializedPerson.Address.State}, {deserializedPerson.Address.ZipCode}");
    }
}
