Question

我有以下用于收集数据的类，然后在Json中返回结构。

public class Outcome {
    public int id { get; set; }
    public string outcome { get; set; }
    public string actionStep { get; set; }
    public List<OutcomeActionResult> actionResults { get; set; }
    public void setData(SqlDataReader reader, DateData dateData) {
        this.id = Convert.ToInt32(reader["id"]);
        this.outcome = Convert.ToString(reader["outcome"]);
        this.actionStep = Convert.ToString(reader["action_step"]);
        this.actionResults = new Outcomes().getActionResultByOutcomeId(this.id, dateData);
    }
}

public class OutcomeActionResult {
    public int id { get; set; }
    public string actionResult { get; set; }
    public ActionResultQuestion question { get; set; }
    public void setData(SqlDataReader reader, DateData dateData) {
        this.id = Convert.ToInt32(reader["id"]);
        this.actionResult = Convert.ToString(reader["action_result"]);
        this.question = new Outcomes().getActionResultQuestionByActionResultId(this.id, dateData);
    } 
}

public class ActionResultQuestion {
    public int id { get; set; }
    public string question { get; set; }
    public bool isMultipleChoice { get; set; }
    public List<MultipleChoiceOption> multipleChoiceOptions { get; set; }
    ActionResultAnswer answer { get; set; }
    public void setData(SqlDataReader reader, DateData dateData) {
        this.id = Convert.ToInt32(reader["id"]);
        this.question = Convert.ToString(reader["question"]);
        this.isMultipleChoice = Convert.ToBoolean(reader["is_multi"]);
        this.answer = new Outcomes().getActionResultAnswersByIdAndDate(this.id, dateData.year, dateData.month, dateData.day, dateData.shiftId);
    }
}

public class ActionResultAnswer {
    public int id { get; set; }
    public string notes { get; set; }
    public int employeeId { get; set; }
    public int selectedAnswer { get; set; }
    public string answer { get; set; }
    public int year { get; set; }
    public int month { get; set; }
    public int day { get; set; }
    public int shiftId { get; set; }
    public void setData(SqlDataReader reader) {
        this.id = Convert.ToInt32(reader["id"]);
        this.notes = Convert.ToString(reader["notes"]);
        this.employeeId = Convert.ToInt32(reader["employee_id"]);
        this.selectedAnswer = reader.IsDBNull(reader.GetOrdinal("selected_answer")) ? -1 : Convert.ToInt32(reader["selected_answer"]);
        this.answer = Convert.ToString(reader["answer"]);
        this.year = Convert.ToInt32(reader["year"]);
        this.month = Convert.ToInt32(reader["month"]);
        this.shiftId = Convert.ToInt32(reader["shift_id"]);
    }
}

正如您所看到的，我有一个Outcome，其中包含一个OutcomeActionResults列表，其中每个都包含一个ActionResultQuestion，它有一个ActionResultAnswer。像这样：

结果 - ＆gt; List（OutcomeActionResult） - ＆gt; ActionResultQuestion - ＆gt; ActionResultAnswer

当我单步执行代码时，所有数据都正确填充，一切正常。但是，当我将对象结构序列化为JSON时，它会序列化除ActionResultAnswer之外的所有内容。基本上，最深层的结构被砍掉了。我一直无法找到任何告诉我为什么会发生这种情况或者如何不发生这种情况的事情。

可能应该把序列化对象的代码放在这里：

var response = outcomes.getOutcomesByClientAndDate(clientId, year, month, day, shiftId, dayOfWeek);
var json = JsonConvert.SerializeObject(response);

answer课程中的ActionResultQuestion媒体资源不公开。因此，默认情况下它不会被Json.Net序列化。

您可以将该属性设为公开...

public ActionResultAnswer answer { get; set; }

或者，如果您打算将其公开，则可以使用[JsonProperty]属性对其进行标记，以允许序列化程序“看到”它：

[JsonProperty]
ActionResultAnswer answer { get; set; }

Newtonsoft Json没有序列化类
