1、用XML文件保存配置信息

<?xml version="1.0"?><ModuleSettings><Server>127.0.0.1</Server><UserName>sa</UserName><Password>123458</Password><Database>KEYTEC</Database></ModuleSettings>

2、XML配置操作类

#region 配置的操作类 ModuleConfig/// <summary>/// 配置项的操作类/// 注意：这里用的是静态方法，所以不需要实例化/// </summary>public class ModuleConfig{//得到配置项对象实例信息public static ModuleSettings GetSettings(){HttpContext context = HttpContext.Current;ModuleSettings data = (ModuleSettings)context.Cache["ModuleSetting"];//从缓存取if (data == null)//缓存里没有{XmlSerializer serializer = new XmlSerializer(typeof(ModuleSettings));try{//从文件取string fileName = HttpContext.Current.Server.MapPath(GetSettingsFile());FileStream fs = new FileStream(fileName, FileMode.Open);data = (ModuleSettings)serializer.Deserialize(fs);//反序列化fs.Close();context.Cache.Insert("ModuleSetting", data, new CacheDependency(fileName));}catch (System.IO.FileNotFoundException){//如果文件不存在，则返回一个空对象data = new ModuleSettings();}}return data;}//保存配置数据public static void SaveSettings(ModuleSettings data){string fileName = HttpContext.Current.Server.MapPath(GetSettingsFile());XmlSerializer serializer = new XmlSerializer(typeof(ModuleSettings));// serialize the objectFileStream fs = new FileStream(fileName, FileMode.Create);serializer.Serialize(fs, data);fs.Close();}//得到配置文件的路径private static string GetSettingsFile(){HttpContext context = HttpContext.Current;string filePath = (string)context.Cache["ModuleSettingFile"];//从缓存取if (filePath == null)//缓存没有{filePath = ConfigurationSettings.AppSettings["ModuleSettingFile"];//从web.config得到context.Cache["ModuleSettingFile"] = filePath;//存入缓存}return filePath;}}#endregion

3、配置类的使用方法

(1)保存配置

//保存配置ModuleSettings setting = new ModuleSettings();setting.Server = "127.0.0.1";setting.UserName = "sa";setting.Password = "123456";setting.Database = "KEYTEC";ModuleConfig.SaveSettings(setting);Response.Write("OK");

(2)读取配置

//读取配置ModuleSettings setting = ModuleConfig.GetSettings();string server = setting.Server;string username = setting.UserName;string pass = setting.Password;string db = setting.Database;Response.Write(server + "," + username + "," + pass + "," + db);
