將Ini檔案儲存換成XML檔案儲存（此處和ini檔案一樣儲存資料庫同步軟體的相關資訊）

該圖是XML檔案寫入格式以及相關資料的方法：

        //XML檔案寫入資料庫同步的基礎資料以及XML設計格式
        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資料庫");
            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!");
        }

該圖是讀取相關資料

//XML讀取資料（資料庫同步相關資料）
        /// <summary>
        /// 返回一個SQLModel的類集合
        /// </summary>
        /// <param name="FilePath">路徑</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;
        }

　　以下是個人見解：

　　　　目前對比下XML以及Ini兩種格式儲存資料，發現Ini用來儲存型別表格的模式就較為繁雜，若是要儲存樹形的資料就更為費勁了；XML可以儲存樹形的資料，功能也更為強大，還支援LinQ，這也是廣大程式設計師選擇XML的原因。後續還會對Json進行相關的學習和交流。
