我无法在 C# 中反序列化为 JSON。是我的类有问题吗？

Question

我在尝试将字符串反序列化为 JSON 时遇到问题。

我正在给 API 打电话。我得到的答案存储在一个变量(body)

Root Api = JsonConvert.DeserializeObject<Root>(body);
//var json = JsonConvert.DeserializeObject<Root>(body);


public partial class All
{
    public int matchsPlayed { get; set; }
    public int win { get; set; }
    public int draw { get; set; }
    public int lose { get; set; }
    public int goalsFor { get; set; }
    public int goalsAgainst { get; set; }
}

public partial class Home
{
    public int matchsPlayed { get; set; }
    public int win { get; set; }
    public int draw { get; set; }
    public int lose { get; set; }
    public int goalsFor { get; set; }
    public int goalsAgainst { get; set; }
}

public partial class Away
{
    public int matchsPlayed { get; set; }
    public int win { get; set; }
    public int draw { get; set; }
    public int lose { get; set; }
    public int goalsFor { get; set; }
    public int goalsAgainst { get; set; }
}

public partial class Standings // Offers
{
    public int rank { get; set; }
    public int team_id { get; set; }
    public string teamName { get; set; }
    public string logo { get; set; }
    public string group { get; set; }
    public string forme { get; set; }
    public string status { get; set; }
    public string description { get; set; }
    public All all { get; set; }
    public Home home { get; set; }
    public Away away { get; set; }
    public int goalsDiff { get; set; }
    public int points { get; set; }
    public string lastUpdate { get; set; }
}



public partial class Api // ProductListing
{
    public int results { get; set; }
   // public Standings[] Standings { get; set; }
    public List<Standings> standings { get; set; }
}

public partial class Root // RootObject
{
    public Api api { get; set; }
}

我收到此错误消息：“

Cannot deserialize the current JSON array (e.g. [1,2,3]) into type 'Standings' because the type requires a JSON object (e.g. {"name":"value"}) to deserialize correctly. To fix this error either change the JSON to a JSON object (e.g. {"name":"value"}) or change the deserialized type to an array or a type that implements a collection interface (e.g. ICollection, IList) like List that can be deserialized from a JSON array. JsonArrayAttribute can also be added to the type to force it to deserialize from a JSON array.

"

这是我要反序列化的整个 json 文本：

Answer 1

如果您更改 Api 的定义，那么 standings 是一个列表列表，它应该可以工作，因为 JSON 有一个数组数组。

public partial class Api // ProductListing
{
    public int results { get; set; }
    public List<List<Standings>> standings { get; set; }
}

我无法在 C# 中反序列化为 JSON。是我的类有问题吗？

i can't deserializing into JSON in C#. Is it something wrong with my classes?
