Question

我的应用程序被拆分为一个配置工具，用于编写配置和一个只读取和使用配置设置的查看器。

在这种情况下，建议使用哪些存储属性的技术？不同类别的XML是一个好主意吗？

这些应用程序正在使用C＃开发，在.NET 3.5上使用WinForms。

Answer 1

XML似乎是理想的选择。

在WinForms中，用户设置通过XML保留，因此您拥有所需的所有类和辅助方法。

我会有一个共享程序集，其中包含您的设置类。然后，您可以将此类序列化/反序列化为硬盘驱动器上的公共位置：

[XmlRoot()]
public class Settings
{
    private static Settings instance = new Settings();

    private Settings() {}

    /// <summary>
    /// Access the Singleton instance
    /// </summary>
    [XmlElement]
    public static Settings Instance
    {
        get
        {
            return instance;
        }
    }

    /// <summary>
    /// Gets or sets the height.
    /// </summary>
    /// <value>The height.</value>
    [XmlAttribute]
    public int Height { get; set; }

    /// <summary>
    /// Main window status (Maximized or not)
    /// </summary>
    [XmlAttribute]
    public FormWindowState WindowState
    {
        get;
        set;
    }

    /// <summary>
    /// Gets or sets a value indicating whether this <see cref="Settings"/> is offline.
    /// </summary>
    /// <value><c>true</c> if offline; otherwise, <c>false</c>.</value>
    [XmlAttribute]
    public bool IsSomething
    {
        get;
        set;
    }

    /// <summary>
    /// Save setting into file
    /// </summary>
    public static void Serialize()
    {
        // Create the directory
        if (!Directory.Exists(AppTmpFolder))
        {
            Directory.CreateDirectory(AppTmpFolder);
        }

        using (TextWriter writer = new StreamWriter(SettingsFilePath))
        {
            XmlSerializer serializer = new XmlSerializer(typeof(Settings));
            serializer.Serialize(writer, Settings.Instance);
        }
    }

    /// <summary>
    /// Load setting from file
    /// </summary>
    public static void Deserialize()
    {
        if (!File.Exists(SettingsFilePath))
        {
            // Can't find saved settings, using default vales
            SetDefaults();
            return;
        }
        try
        {
            using (XmlReader reader = XmlReader.Create(SettingsFilePath))
            {
                XmlSerializer serializer = new XmlSerializer(typeof(Settings));
                if (serializer.CanDeserialize(reader))
                {
                    Settings.instance = serializer.Deserialize(reader) as Settings;
                }
            }
        }
        catch (System.Exception)
        {
            // Failed to load some data, leave the settings to default
            SetDefaults();
        }
    }
}

您的xml文件将如下所示：

<?xml version="1.0" encoding="utf-8"?>
<Settings xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" Height="738" WindowState="Maximized" IsSomething="false" >
</Settings>

在两个应用程序之间共享配置的技术？
