XML串行器不能在屬性上工作

Question

在我正在處理的代碼中，有一些屬性被序列化。儘管我可以看到它們都很好，但只有一個。下面的代碼：

// Fields that the properties use. 
    private bool _useAlertColors = false; 
    private List<Int32> _colorArgb = new List<Int32>(new Int32[]{Color.White.ToArgb(), Color.Yellow.ToArgb(), Color.Red.ToArgb()}); 

    // The one that does not work. 
    public List<Color> AlertColors 
    { 
     get 
     { 
      List<Color> alertColors = new List<Color>(); 

      foreach (Int32 colorValue in _colorArgb) 
      { 
       alertColors.Add(Color.FromArgb(colorValue)); 
      } 

      return alertColors; 
     } 

     set 
     { 
      // If there's any difference in colors 
      // then add the new color 
      for (int i = 0; i < _colorArgb.Count; i++) 
      { 
       if (_colorArgb[i] != value[i].ToArgb()) 
       { 
        _colorArgb[i] = value[i].ToArgb(); 
        HasChanged = true; 
       } 

      } 
     } 
    } 

    // One of those that work. 
    public bool UseAlertColors 
    { 
     get 
     { 
      return _useAlertColors; 
     } 

     set 
     { 
      if (_useAlertColors != value) 
      { 
       _useAlertColors = value; 
       HasChanged = true; 
      } 
     } 
    } 

    // Serializing method. 
    public bool Serialize(string filePath) 
    { 
     if (string.IsNullOrEmpty(filePath)) 
     { 
      Logger.Log("Can't save settings, empty or null file path."); 

      return false; 
     } 

     FileStream fileStream = null; 

     try 
     { 
      fileStream = new FileStream(filePath, FileMode.Create); 
      FilePath = filePath; 
      System.Xml.Serialization.XmlSerializerFactory xmlSerializerFactory = 
       new XmlSerializerFactory(); 
      System.Xml.Serialization.XmlSerializer xmlSerializer = 
       xmlSerializerFactory.CreateSerializer(typeof(Settings)); 

      xmlSerializer.Serialize(fileStream, this); 

      Logger.Log("Settings have been saved successfully to the file " + filePath); 
     } 
     catch (ArgumentException argumentException) 
     { 
      Logger.Log("Error while saving the settings. " + argumentException.Message); 

      return false; 
     } 
     catch (IOException iOException) 
     { 
      Logger.Log("Error while saving the settings. " + iOException.Message); 

      return false; 
     } 
     finally 
     { 
      if (fileStream != null) 
       fileStream.Close(); 
     } 

     return true; 
    } 

序列化之後，這是我結束了：

<UseAlertColors>true</UseAlertColors> 
    <AlertColors> 
    <Color /> 
    <Color /> 
    <Color /> 
    </AlertColors> 

什麼是錯的AlertColors財產？爲什麼它沒有序列化？

編輯：我已經相應改變的AlertColors財產，它仍然是不工作：

public List<int> AlertColors 
    { 
     get 
     { 
      return _colorArgb; 
     } 

     set 
     { 
      // If there's any difference in colors 
      // then add the new color 
      for (int i = 0; i < _colorArgb.Count; i++) 
      { 
       if (_colorArgb[i] != value[i]) 
       { 
        _colorArgb[i] = value[i]; 
        HasChanged = true; 
       } 

      } 
     } 
    } 

我得到的.xml文件是這樣的：

<AlertColors> 
    <int>-1</int> 
    <int>-8355840</int> 
    <int>-65536</int> 
    </AlertColors> 

哪些在_colorArgb字段初始化時設置的第一個值。我可以在程序執行期間看到字段的變化，但是當覆蓋屬性被序列化時，它會與基礎字段的初始值進行序列化。

是什麼導致了這個問題？

XMLSerializer僅在序列化時使用類的公共屬性 - Color類沒有。
