如何反序列化对象json列表由NewtonSoft

Question

我序列化下面的类Newtonsoft。Json，但我不能反序列化相同的Json Newtonsoft.Json。我怎么能做到呢?

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; }
}

我的反序列化器是:

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

但是产生错误:

类型为'Newtonsoft.Json '的未处理异常。JsonSerializationException'在Newtonsoft.Json.dll中发生

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

我怎么解决它?我怎么能反序列化我的对象列表到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，但它不是一个数组的UserEvents
