浅谈序列化之 XmlSerializer

在程序设计中，有时需要保存当前对象的状态信息，待需要时直接转换为对象。此处记录 XmlSerializer 类的相关操作，即序列化为xml 和反序列化为 object.

1、序列化对象并保存到 valid.xml 文件

            ElementConfig config = new ElementConfig();
            Comment cmt = new Comment();
            cmt.CreatedBy = "Zhao";
            cmt.CreatedDate = DateTime.Now;
            cmt.Guid = new Guid();
            cmt.Message = "Hello";
            config.Comments = new Comment[] { cmt};
            BpmPropertyText bpmText = new BpmPropertyText();
            bpmText.UniqueName = "WWW";
            bpmText.Visible = true;
            config.Properties = new BpmProperty[] { bpmText};
            XmlSerializer ser = new XmlSerializer(typeof(ElementConfig));
            FileStream fs = new FileStream("valid.xml", FileMode.Create, FileAccess.Write);
            ser.Serialize(fs,config);

2、读取 valid.xml 并反序列化

            XmlSerializer ser = new XmlSerializer(typeof(ElementConfig));
            FileStream fs = File.Open("valid.xml", FileMode.Open, FileAccess.Read);
            ElementConfig o = (ElementConfig)ser.Deserialize(fs);
            fs.Close();
