Newtonsoft Json不是序列化類

Question

我有我正在使用的以下類來收集數據，然後返回Json中的結構。

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"]); 
    } 
} 

正如你所看到的，我有結果包含OutcomeActionResults的列表中的每個都包含其中有一個ActionResultAnswer的ActionResultQuestion。事情是這樣的：

成果 - >列表（OutcomeActionResult） - > ActionResultQuestion - > ActionResultAnswer

當我通過代碼，所有的數據被正確填充，一切都很好。但是，當我將對象結構序列化爲JSON時，它將序列化除ActionResultAnswer之外的所有內容。基本上最深層的結構被切斷。我一直無法找到任何能夠告訴我爲什麼會發生這種情況的原因，以及如何避免這種情況發生。

或許應該把那個在這裏序列化對象的代碼：

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

Answer 1

的answer財產在你ActionResultQuestion類是不公開的。因此，默認情況下它不會被Json.Net序列化。

您可以讓屬性public ...

public ActionResultAnswer answer { get; set; } 

或者，如果你打算，這不是公開的，你可以用一個[JsonProperty]屬性標記它允許串行「看到」它：

[JsonProperty] 
ActionResultAnswer answer { get; set; }
