用Json.Net去除MongoDB.Bson.ObjectId返回错误的结果

Question

    var serialize = JsonConvert.SerializeObject(ObjectId.GenerateNewId());
    var deserialize = JsonConvert.DeserializeObject<ObjectId>(serialize);

deserialize包含无效值{000000000000000000000000}

MongoDB.Driver(2.4.4)
Newtonsoft.Json(10.0.2) 

我做错了什么？
