因为一些配置属性比较多，存在多组属性，因此结合xml解析、缓存技术，实现配置文化的自动解析、存入缓存、缓存依赖实时更新配置内容。
配置文件反序列化存入缓存的核心方法：
public Class.Settings GetSettings() { if (HttpRuntime.Cache["settings"] != null) return (Class.Settings)HttpRuntime.Cache["settings"]; string rootPath = GetPath(); #region rootPath if (rootPath == "") { log.Write(MsgType.Fatal, "配置文件根目录rootPath为空"); return null; } else { if (!rootPath.EndsWith("\\")) rootPath += "\\"; rootPath = rootPath + "settings\\settings.config"; } #endregion if (!File.Exists(rootPath)) { log.Write(MsgType.Fatal, "配置文件根目录rootPath为空"); return null; } string content = File.ReadAllText(rootPath, Encoding.Default); Class.Settings model = PublicMethod.XmlSerialize.DeserializeXML<Class.Settings>(content); log.Write(MsgType.Information, "读取配置文件"); CacheDependency cd = new CacheDependency(rootPath); HttpRuntime.Cache.Add("settings", model, cd, DateTime.Now.AddMinutes(5), TimeSpan.Zero, CacheItemPriority.High, null); return model; }
上面自动获取rootPath的方法：
/// <summary> /// 取当前根目录的方法 /// </summary> private static string GetPath() { string rootPath = ""; System.Diagnostics.Process p = System.Diagnostics.Process.GetCurrentProcess(); //WebDev.WebServer visual studio web server //xxx.vhost Winform //w3wp IIS7 //aspnet_wp IIS6 //iisexpress vs2013 string processName = p.ProcessName.ToLower(); if (processName == "aspnet_wp" || processName == "w3wp" || processName == "webdev.webserver" || processName == "iisexpress") { if (System.Web.HttpContext.Current != null) rootPath = System.Web.HttpContext.Current.Server.MapPath("~/"); else //当控件在定时器的触发程序中使用时就为空 { rootPath = System.AppDomain.CurrentDomain.BaseDirectory; } } return rootPath; }
Settings实体类的定义，要注意，这里的实体类要和settings配置文件对应，否则反序列化会出错：
[XmlRoot(Namespace = "", IsNullable = false, ElementName = "settings")] public class Settings { #region 属性 [XmlElement("logger")] public LoggerConfig logger { get; set; } #endregion #region 子类 [XmlType(TypeName = "logger")] public class LoggerConfig { public string loglevel { get; set; } public string savepath { get; set; } } #endregion }
settings.config的内容实例
