Class 到 XML 的序列化会留下空白值

Question

很难解释，任何人都可以找出问题所在吗？

我正在将 class 序列化为 XML，但是其中一个属性（Class 中的 public Class）被赋予空白XML.

中的值

我正在创建自己的设置 Class，我正在将其序列化为 XML 并反序列化回应用程序的 class 加载。

我已将调试点放入 Save 方法中，"ColourScheme" 确实有值，但它们在 XML 中被屏蔽了。

public class SettingsModel
{
    // DECLARE: Settings File Location
    private static string SettingsFilePath = String.Format(@"{0}\{1}\{2}", Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData), "Typhoeus BluePrint", "BluePrint_Settings.xml");

    // DECLARE: Public Settings
    public DateTime LastUpdated = System.DateTime.Now;
    public string StylesheetName = "style.css";
    public string WebPageName = "index.html";
    public string ProjectDirectory = String.Format(@"{0}\{1}\{2}", Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments), "Typhoeus BluePrint", "Projects");
    public ColourSchemeClass ColourScheme = new ColourSchemeClass();

    public SettingsModel()
    {

    }

    public void Save()
    {
        LastUpdated = System.DateTime.Now;

        // DECLARE: File Stream Object
        FileStream fs = new FileStream(SettingsFilePath, FileMode.OpenOrCreate);

        // DECLARE: Serialisation Parameters
        XmlSerializer ClassSerialiser = new XmlSerializer(typeof(SettingsModel));

        // SERIALISE: This Class to XML
        ClassSerialiser.Serialize(fs, this);

        // CLOSE: File Stream
        fs.Close();
    }
}

这是配色方案Class

public class ColourSchemeClass
{
    #region Objects

    // DECLARE: Colour Scheme Properties
    public Color BaseColour = ColorTranslator.FromHtml("#1E1E1E");
    public Color HighlightColour = ColorTranslator.FromHtml("#414141");
    public Color SelectedColour = Color.White;

    #endregion
    #region Constructors

    public ColourSchemeClass()
    {

    }
    public ColourSchemeClass (Color Base, Color Highlight, Color Selected)
    {
        BaseColour = Base;
        HighlightColour = Highlight;
        SelectedColour = Selected;
    }

    #endregion
}

这是连载后的XML。（摘录因为我这里好像没法格式化）（替换标签用方括号打开和关闭）

[ColourScheme]
[BaseColour/]
[HighlightColour/]
[SelectedColour/]
[/ColourScheme]

Color is immutable (no setters) so it can't be usefully serialized by XmlSerializer。你需要为每个颜色属性引入一个代理属性，例如：

    [XmlIgnore]
    public Color BaseColour { get; set; }

    [Browsable(false), EditorBrowsable(EditorBrowsableState.Never)]
    [DebuggerBrowsable(DebuggerBrowsableState.Never)]
    [XmlElement("BaseColour")]
    public string XmlBaseColour
    {
        get
        {
            return ColorTranslator.ToHtml(BaseColour);
        }
        set
        {
            BaseColour = ColorTranslator.FromHtml(value);
        }
    }
