我無法在 C# 中反序列化為 JSON。 我的課有問題嗎？

Question

嘗試將字符串反序列化為 JSON 時遇到問題。

我正在調用 API。 我得到的答案存儲在變量（主體）中

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; }
}

我收到此錯誤消息：“

無法將當前 JSON 數組（例如 [1,2,3]）反序列化為“Standings”類型，因為該類型需要 JSON 對象（例如 {"name":"value"}）才能正確反序列化。 要修復此錯誤，請將 JSON 更改為 JSON 對象（例如 {"name":"value"}）或將反序列化類型更改為數組或實現集合接口的類型（例如 ICollection、IList），例如可以從 JSON 數組反序列化。 JsonArrayAttribute 也可以添加到類型以強制它從 JSON 數組反序列化。

”

這是我試圖反序列化的整個 json 文本：

Answer 1

如果您更改Api的定義，則standings是一個列表列表，它應該可以工作，因為 JSON 有一個數組數組。

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