反序列化 json 数据 c#

Question

我想反序列化 JSON 通过 Telegram Bot API by getUpdate() 方法收到的响应。

JSON数据：

    }
  ]
}

我已经从 json2csharp

生成了类

public class From
{
    public int id { get; set; }
    public string first_name { get; set; }
    public string last_name { get; set; }
    public string username { get; set; }
}

public class Chat
{
    public int id { get; set; }
    public string first_name { get; set; }
    public string last_name { get; set; }
    public string type { get; set; }
    public string username { get; set; }
}

public class Entity
{
    public string type { get; set; }
    public int offset { get; set; }
    public int length { get; set; }
}

public class Message
{
    public int message_id { get; set; }
    public From from { get; set; }
    public Chat chat { get; set; }
    public int date { get; set; }
    public string text { get; set; }
    public List<Entity> entities { get; set; }
}

public class Result
{
    public int update_id { get; set; }
    public Message message { get; set; }
}

public class RootObject
{
    public bool ok { get; set; }
    public List<Result> result { get; set; }
}

使用 newtonsoft 反序列化

var d = Newtonsoft.Json.JsonConvert.DeserializeObject(rcvd_data);

接下来要做什么？如何让这一切发挥作用？我很困惑，请帮助。

Answer 1

要反序列化，请使用此代码：

RootObject ro = JsonConvert.DeserializeObject<RootObject>(rcvd_data);

在 ro 中，您拥有所有数据。

示例

bool ok = ro.ok;

foreach(Result r in ro.result)
{
    int uId = r.update_id;
    Message m = r.message;
    int msgId = m.message_id;
}

Answer 2

试试这个方法

var d = Newtonsoft.Json.JsonConvert.DeserializeObject<RootObject>(rcvd_‌data);

然后 d 将包含 RootObject 的列表。通过使用 foreach 进行迭代，您可以获得 RootObject 模型

的所有属性

Answer 3

string data = @"{""ok"":true,""result"":[{""update_id"":920493886,...";

RootObject ro = Newtonsoft.Json.JsonConvert.DeserializeObject<RootObject>(data);

foreach (Result result in ro.result)
{
        //two example fields
        Console.WriteLine("update_id= " + result.update_id);
        Console.WriteLine("message text= "+result.message.text);
}

Answer 4

基于：https://yts.am/api/v2/list_movies.json (Source: https://yts.am/api)

我使用了：http://json2csharp.com/ 创建了类 Copy and paste the result of the get request of postman to json2csharp to automatically create the classes that you need

创建后，我将它们用于这样的服务：

 private string URL = "https://yts.am/api/v2/list_movies.json";
    public async Task<List<Movie>> GetMovies()
    {
        var httpClient = new HttpClient();
        var json = await httpClient.GetStringAsync(URL);
        RootObject lista = Newtonsoft.Json.JsonConvert.DeserializeObject<RootObject>(json);
        List<Movie> todoes = lista.data.movies;
        return todoes;
    }
