C#对XML文件的读写
将Ini文件存储换成XML文件保存(此处和ini文件一样保存数据库同步软件的相关信息)
这是一个和书店相关的XML写入方法:
//XML文件写方法 //编写XML文件的格式并存储到指定的FilePath(路径) internal void WriterXML(string FilePath) { try { XmlDocument doc = new XmlDocument();//声明一个XmlDocument作为XML文档的容器 //XmlDeclaration xmlDec = doc.CreateXmlDeclaration("1.0", "UTF-8", "yes"); XmlElement BookStory = doc.CreateElement("BookStory");//XMLElement表示一个标记或者元素的开始 XmlAttribute Address = doc.CreateAttribute("Address");//XmlAttribute表示一个标记或者元素的属性 Address.InnerText = "福建省厦门市集美新馆";//InnerText表示某一元素的内容 BookStory.SetAttribute("Type", "On_Line"); BookStory.SetAttribute("CreatTime", DateTime.Now.ToLongTimeString()); XmlElement Book = doc.CreateElement("Book"); XmlElement Tittle = doc.CreateElement("Tittle"); Tittle.SetAttribute("Type", "BooksName"); Tittle.InnerText = "C#7.0核心技术指南"; XmlElement Price = doc.CreateElement("Price"); Price.SetAttribute("Type", "RMB"); Price.InnerText = "259.00"; //doc.AppendChild(xmlDec); doc.AppendChild(BookStory); BookStory.AppendChild(Book); BookStory.Attributes.Append(Address); Book.AppendChild(Tittle); Book.AppendChild(Price); XmlWriterSettings settings = new XmlWriterSettings();//指定XMLWriter类实现的功能 settings.Indent = true; settings.Encoding = Encoding.UTF8;//定义编码格式 XmlWriter writer = XmlWriter.Create(FilePath, settings);//Create 方法使用 XmlWriterSettings 类指定要在创建的 XmlWriter 对象中实现哪些功能。 doc.WriteTo(writer); writer.Flush();//清除缓存区 writer.Close(); MessageBox.Show("This Ok!"); } catch (Exception ex) { MessageBox.Show(ex.Message); } }
结果截图:
以下是对XML文件读写的学习以后根据自己的需求的衍生:
该图是XML文件写入格式以及相关数据的方法:
//XML文件写入数据库同步的基础数据以及XML设计格式 internal void WriterInfo(string FilePath) { XmlDocument doc = new XmlDocument(); XmlElement XML = doc.CreateElement("XML"); XmlElement Conn = doc.CreateElement("Conn"); Conn.SetAttribute("Name","Conn1"); Conn.SetAttribute("Type", "SQL Server数据库"); XmlElement Source = doc.CreateElement("Source"); XmlElement SServer = doc.CreateElement("SServer"); XmlElement SIdentity = doc.CreateElement("SIdentity"); XmlElement SDataBase = doc.CreateElement("SDataBase"); XmlElement SUserID = doc.CreateElement("SUserID"); XmlElement SPwd = doc.CreateElement("SPwd"); XmlElement Target = doc.CreateElement("Target"); XmlElement TServer = doc.CreateElement("TServer"); XmlElement TIdentity = doc.CreateElement("TIdentity"); XmlElement TDataBase = doc.CreateElement("TDataBase"); XmlElement TUserID = doc.CreateElement("TUserID"); XmlElement TPwd = doc.CreateElement("TPwd"); doc.AppendChild(XML); XML.AppendChild(Conn); Conn.AppendChild(Source); Conn.AppendChild(Target); Source.AppendChild(SServer); Source.AppendChild(SIdentity); Source.AppendChild(SDataBase); Source.AppendChild(SUserID); Source.AppendChild(SPwd); Target.AppendChild(TServer); Target.AppendChild(TIdentity); Target.AppendChild(TDataBase); Target.AppendChild(TUserID); Target.AppendChild(TPwd); SServer.InnerText = "123.123.123"; TServer.InnerText = "00000000"; XmlWriterSettings settings = new XmlWriterSettings(); settings.Indent = true; settings.Encoding = Encoding.UTF8; XmlWriter writer = XmlWriter.Create(FilePath,settings); doc.WriteTo(writer); writer.Flush(); writer.Close(); MessageBox.Show("It's Ok!"); }
该图是读取相关数据
//XML读取数据(数据库同步相关数据) /// <summary> /// 返回一个SQLModel的类集合 /// </summary> /// <param name="FilePath">路径</param> /// <returns></returns> internal List<SQLModel> XMLReaders(string FilePath) { List<SQLModel> XMLInfo = new List<SQLModel>(); XmlDocument doc = new XmlDocument(); doc.Load(FilePath); XmlNode node1 = doc.SelectSingleNode("XML"); /*XmlNode node2 = node1.SelectSingleNode("Conn"); XmlNode node3 = node2.SelectSingleNode("Source");*/ XmlNodeList node = node1.ChildNodes;//node = Conn1,Conn2.... foreach (XmlNode item in node) {//this level is Conn SQLModel sQL = new SQLModel(); XmlElement xml = (XmlElement)item;//item = one of Conn = xml sQL.ConnName = xml.GetAttribute("Name").ToString(); sQL.Type = xml.GetAttribute("Type").ToString(); XmlNodeList Second = item.ChildNodes;//Second = Source and Target foreach (XmlNode Snode in Second) { if (Snode.Name == "Source") { XmlNodeList SnodeChild = Snode.ChildNodes; sQL.SServer = SnodeChild.Item(0).InnerText; sQL.SIdentity = SnodeChild.Item(1).InnerText; sQL.SDataBase = SnodeChild.Item(2).InnerText; sQL.SUserID = SnodeChild.Item(3).InnerText; sQL.SPwd = SnodeChild.Item(4).InnerText; } if (Snode.Name == "Target") { XmlNodeList SnodeChild = Snode.ChildNodes; sQL.TServer = SnodeChild.Item(0).InnerText; sQL.TIdentity = SnodeChild.Item(1).InnerText; sQL.TDataBase = SnodeChild.Item(2).InnerText; sQL.TUserID = SnodeChild.Item(3).InnerText; sQL.TPwd = SnodeChild.Item(4).InnerText; } } XMLInfo.Add(sQL); } return XMLInfo; }
结果截图:
以下是个人见解:
目前对比下XML以及Ini两种格式存储数据,发现Ini用来存储类型表格的模式就较为繁杂,若是要存储树形的数据就更为费劲了;XML可以存储树形的数据,功能也更为强大,还支持LinQ,这也是广大程序员选择XML的原因。后续还会对Json进行相关的学习和交流。
