读书笔记：《亮剑 .Net》——将类转化为XML并保存已经去读后反序列化为类对象

简历一个可序列化的类

 

/// <summary>
    /// 配置的Modul类，即：保存的配置项(可以自定义成自己的项)
    /// 注意相关属性的类型与[XmlElement]
    /// </summary>
    public class ModuleSettings
    {
        private string server;
        private string username;
        private string password;
        private string database;
        

        [XmlElement]
        public string Server
        {
            set { server = value; }
            get { return server; }
        }
        [XmlElement]
        public string UserName
        {
            set { username = value; }
            get { return username; }
        }
        [XmlElement]
        public string Password
        {
            set { password = value; }
            get { return password; }
        }
        [XmlElement]
        public string Database
        {
            set { database = value; }
            get { return database; }
        }
    }

 

序列化后保存

 

public static void SaveSettings(ModuleSettings data)
        {
            string fileName = HttpContext.Current.Server.MapPath(GetSettingsFile());
            XmlSerializer serializer = new XmlSerializer(typeof(ModuleSettings));

            // serialize the object
            FileStream fs = new FileStream(fileName, FileMode.Create);
            serializer.Serialize(fs, data);
            fs.Close();
        }

 

读取后反序列化

 

 

//得到配置项对象实例信息
        public static ModuleSettings GetSettings()
        {
            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);                    
                return data = (ModuleSettings)serializer.Deserialize(fs);//反序列化
                fs.Close();
            }
            catch (System.IO.FileNotFoundException)
            {
                    //如果文件不存在，则返回一个空对象
                return data = null
            }
        }
