使用 C# 反序列化 JSON [英] Deserialize JSON with C#

问题描述

我正在尝试将 Facebook 朋友的 Graph API 调用反序列化为对象.JSON 对象如下所示:

I'm trying to deserialize a Facebook friend's Graph API call into a list of objects. The JSON object looks like:

{"data":[{"id":"518523721","name":"ftyft"},
         {"id":"527032438","name":"ftyftyf"},
         {"id":"527572047","name":"ftgft"},
         {"id":"531141884","name":"ftftft"},
         {"id":"532652067","name"...

List<EFacebook> facebooks = new JavaScriptSerializer().Deserialize<List<EFacebook>>(result);

它不起作用，因为原始对象无效.我该如何反序列化它?

It's not working, because the primitive object is invalid. How can I deserialize this?

推荐答案

你需要创建一个这样的结构:

You need to create a structure like this:

public class Friends
{

    public List<FacebookFriend> data {get; set;}
}

public class FacebookFriend
{

    public string id {get; set;}
    public string name {get; set;}
}

那么你应该可以:

Friends facebookFriends = new JavaScriptSerializer().Deserialize<Friends>(result);

我的课程名称只是一个例子.你应该使用专有名称.

The names of my classes are just an example. You should use proper names.

添加示例测试:

string json =
    @"{""data"":[{""id"":""518523721"",""name"":""ftyft""}, {""id"":""527032438"",""name"":""ftyftyf""}, {""id"":""527572047"",""name"":""ftgft""}, {""id"":""531141884"",""name"":""ftftft""}]}";

Friends facebookFriends = new System.Web.Script.Serialization.JavaScriptSerializer().Deserialize<Friends>(json);

foreach(var item in facebookFriends.data)
{
    Console.WriteLine("id: {0}, name: {1}", item.id, item.name);
}

产生:

id: 518523721, name: ftyft
id: 527032438, name: ftyftyf
id: 527572047, name: ftgft
id: 531141884, name: ftftft
