copied!<p>I would have a shared assembly, which contains your settings class. You can then serialize/deserialize this class to a common place on the hard drive:</p> <pre><code>[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(); } } } </code></pre> <p>Your xml file will then look like this:</p> <pre><code><?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> </code></pre>
