我正在尝试将JSON转换为对象以轻松访问统计信息。我目前得到的词典和词典的空值。如果有人能提供帮助，我们将不胜感激。
以下是我的JSON示例：
{
"teamStats": {
"game2998": {
"dateTime": "2014-05-23T19:00Z",
"team304": {
"teamId": 304,
"teamName": "Cloud9 ",
"matchVictory": 1,
"matchDefeat": 0,
"baronsKilled": 2,
"dragonsKilled": 4,
"firstBlood": 0,
"firstTower": 0,
"firstInhibitor": 1,
"towersKilled": 10
},
"team1": {
"teamId": 1,
"teamName": "Team SoloMid",
"matchVictory": 0,
"matchDefeat": 1,
"baronsKilled": 0,
"dragonsKilled": 1,
"firstBlood": 1,
"firstTower": 1,
"firstInhibitor": 0,
"towersKilled": 5
},
"matchId": "2515"
}
},
"playerStats": {
"game2998": {
"dateTime": "2014-05-23T19:00Z",
"matchId": "2515",
"player328": {
"playerId": 328,
"kills": 1,
"deaths": 1,
"assists": 7,
"minionKills": 254,
"doubleKills": 0,
"tripleKills": 0,
"quadraKills": 0,
"pentaKills": 0,
"playerName": "Balls",
"role": "Top Lane"
},
"player329": {
"playerId": 329,
"kills": 4,
"deaths": 0,
"assists": 7,
"minionKills": 155,
"doubleKills": 1,
"tripleKills": 0,
"quadraKills": 0,
"pentaKills": 0,
"playerName": "Meteos",
"role": "Jungler"
}
}
}
}
以下是我的课程示例：
public class RootObject
{
public Dictionary<string, GameT> teamStats { get; set; }
public Dictionary<string, GameP> playerStats { get; set; }
}
public class GameT
{
public string dateTime { get; set; }
public Dictionary<string, Team> blueTeam { get; set; }
public Dictionary<string, Team> purpleTeam { get; set; }
public string matchId { get; set; }
}
public class Team
{
public int teamId { get; set; }
public string teamName { get; set; }
public int matchVictory { get; set; }
public int matchDefeat { get; set; }
public int baronsKilled { get; set; }
public int dragonsKilled { get; set; }
public int firstBlood { get; set; }
public int firstTower { get; set; }
public int firstInhibitor { get; set; }
public int towersKilled { get; set; }
}
public class GameP
{
public string dateTime { get; set; }
public string matchId { get; set; }
public Dictionary<string, Player> blueTop { get; set; }
public Dictionary<string, Player> blueJungle { get; set; }
}
public class Player
{
public int playerId { get; set; }
public int kills { get; set; }
public int deaths { get; set; }
public int assists { get; set; }
public int minionKills { get; set; }
public int doubleKills { get; set; }
public int tripleKills { get; set; }
public int quadraKills { get; set; }
public int pentaKills { get; set; }
public string playerName { get; set; }
public string role { get; set; }
}

由于您的JSON将团队和玩家列表与游戏属性（日期和匹配ID）混合在一起，因此您需要使用自定义JsonConverter使其适用于类中的强类型词典。我将在下面解释你如何做到这一点。
首先，像这样定义你的类：
public class RootObject
{
public Dictionary<string, Game<Team>> teamStats { get; set; }
public Dictionary<string, Game<Player>> playerStats { get; set; }
}
public class Game<T>
{
public string dateTime { get; set; }
public string matchId { get; set; }
public Dictionary<string, T> items { get; set; }
}
public class Team
{
public int teamId { get; set; }
public string teamName { get; set; }
public int matchVictory { get; set; }
public int matchDefeat { get; set; }
public int baronsKilled { get; set; }
public int dragonsKilled { get; set; }
public int firstBlood { get; set; }
public int firstTower { get; set; }
public int firstInhibitor { get; set; }
public int towersKilled { get; set; }
}
public class Player
{
public int playerId { get; set; }
public int kills { get; set; }
public int deaths { get; set; }
public int assists { get; set; }
public int minionKills { get; set; }
public int doubleKills { get; set; }
public int tripleKills { get; set; }
public int quadraKills { get; set; }
public int pentaKills { get; set; }
public string playerName { get; set; }
public string role { get; set; }
}
定义一个通用的JsonConverter，它可以处理JSON的“Game”部分，将日期和匹配ID与其余项目分开：
public class GameConverter<T> : JsonConverter
{
public override bool CanConvert(Type objectType)
{
return (objectType == typeof(Game<T>));
}
public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
{
JObject jo = JObject.Load(reader);
Game<T> game = new Game<T>();
game.dateTime = jo["dateTime"].ToString();
game.matchId = jo["matchId"].ToString();
game.items = new Dictionary<string, T>();
foreach (JProperty prop in jo.Properties())
{
if (prop.Value.Type == JTokenType.Object)
{
game.items.Add(prop.Name, prop.Value.ToObject<T>());
}
}
return game;
}
public override bool CanWrite
{
get { return false; }
}
public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
{
throw new NotImplementedException();
}
}
使用转换器后，您可以按如下方式反序列化（请注意，我们需要两个转换器实例，一个用于处理团队列表，另一个用于处理播放器列表）：
JsonSerializerSettings settings = new JsonSerializerSettings();
settings.Converters.Add(new GameConverter<Team>());
settings.Converters.Add(new GameConverter<Player>());
RootObject root = JsonConvert.DeserializeObject<RootObject>(json, settings);

你的JSON中没有名为blueTeam和purpleTeam的属性。
也许它应该是这样的：
"teamStats": {
"game2998": {
"dateTime": "2014-05-23T19:00Z",
"blueTeam": {
"team304": {
"teamId": 304,
[...]
}},
"purpleTeam": {
"team1": {
"teamId": 1,
[...]
}},
"matchId": "2515"
}
