我需要使用Newtonsoft.Json将JSON数组转换为C#类，但我不知道如何做到这一点。
我已经试过用

public  LeagueInfo[] leagueinfo { get; set; }

字符串
和

public  List<LeagueInfo> leagueinfo { get; set; }

型
我现在拥有的是：

public class League
    {
        public  LeagueInfo[] leagueinfo { get; set; }
    }
    
    public class LeagueInfo
    {
        public string queueType { get; set; }
        public string summonerName { get; set; }
        public bool hotStreak { get; set; }
        public int wins { get; set; }
        public bool veteran { get; set; }
        public int losses { get; set; }
        public string rank { get; set; }
        public string tier { get; set; }
        public bool inactive { get; set; }
        public bool freshBlood { get; set; }
        public string leagueId { get; set; }
        public string summonerId { get; set; }
        public int leaguePoints { get; set; }
    }

league = JsonConvert.DeserializeObject<League>(data);

的字符串
当我尝试这样做时，我得到了这个错误：

Newtonsoft.Json.JsonSerializationException: 'Cannot deserialize the current JSON array (e.g. [1,2,3]) into type 'League' 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<T> 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.
    Path '', line 1, position 1.'
