如何通过NewtonSoft反序列化对象json列表?

问题描述 投票:3回答:1

我通过Newtonsoft.Json在类下面进行序列化,但我无法通过Newtonsoft.Json反序列化相同的json。我怎样才能做到这一点?

JSON:

"{\"UserEvents\":[{\"id\":1214308,\"Date\":20150801000000,\"IsRead\":true}]}"

我的实体:

   public class UserEventLog {
    [JsonProperty("UserEvents")]
    public List<UserEvent> UserEvents { get; set; }
    public UserEventLog() {
        UserEvents = new List<UserEvent>();
    }
}


public class UserEvent {
    [JsonProperty("id")]
    public long id{ get; set; }
      [JsonProperty("Date")]
    public long Date{ get; set; }
      [JsonProperty("IsRead")]
    public bool IsRead { get; set; }
}

我的解串器是这样的:

  List<UserEventLog> convert = JsonConvert.DeserializeObject<List<UserEventLog>>(user.ToString()) as List<UserEventLog>;

但错误产生:

Newtonsoft.Json.dll中发生未处理的“Newtonsoft.Json.JsonSerializationException”类型异常

其他信息:将值"{"UserEvents":[{"id":1214308,"Date":20150801000000,"IsRead":true}]}"转换为类型'System.Collections.Generic.List`1时出错

我怎么解决呢?我怎样才能将我的对象列表反序列化为UserEvents列表?

这适用于linqpad:

void Main()
{
    var user = "{\"UserEvents\":[{\"id\":1214308,\"Date\":20150801000000,\"IsRead\":true}]}";
    UserEventLog convert = JsonConvert.DeserializeObject<UserEventLog>(user.ToString());
    convert.UserEvents.Count().Dump();
}

public class UserEventLog 
{
    [JsonProperty("UserEvents")]
    public List<UserEvent> UserEvents { get; set; }

    public UserEventLog() 
    {
        UserEvents = new List<UserEvent>();
    }
}


public class UserEvent 
{
    [JsonProperty("id")]
    public long id { get; set; }

    [JsonProperty("Date")]
    public long Date { get; set; }

    [JsonProperty("IsRead")]
    public bool IsRead { get; set; }
}

问题是你试图反序列化到列表中,但它不是UserEvents的数组
