C# XmlSerializer将对象序列化以及反序列化（Sqlite数据库）

获取不同数据库表信息将筛选出来的信息序列化以及反序列化

相应类结构：

Class Tables:

     [Serializable]
     [XmlRoot("Table")]
     public class Tables
     {
         public Tables()
         {
             Items = new List<ColumnsItems>();
         }

         /// <summary>
         /// 新表名称
         /// </summary>
         [XmlElementAttribute("NewTableName")]
         public string NewTableName { get; set; }

         /// <summary>
         /// 旧表名称
         /// </summary>
         [XmlElementAttribute("OldTableName")]
         public string OldTableName { get; set; }

         [XmlElementAttribute("Field")]
         public List<ColumnsItems> Items { get; set; }

     }

Class ColumnsItems:

     [Serializable]
     [XmlRoot("Field")]
     public class ColumnsItems
     {
         /// <summary>
         /// 新表字段
         /// </summary>
         [XmlElementAttribute("NewColumn")]
         public string NewColumn { get; set; }

         /// <summary>
         /// 旧表字段
         /// </summary>
         [XmlElementAttribute("OldColumn")]
         public string OldColumn { get; set; }
     }

Class createXml:

     [Serializable]
     [XmlRoot("Tables")]
     public class createXml
     {
         public createXml()
         {
             setTable = new List<Tables>();
         }
         [XmlElementAttribute("Table")]
         public List<Tables> setTable { get; set; }
     }

对比表格序列化：

         #region 将对比表格序列化
         /// <summary>
         /// 保存信息事件,将表中数据对应关系读取到XML文件中
         /// </summary>
         /// <param name="sender"></param>
         /// <param name="e"></param>
         private void saveInfo_Click(object sender, EventArgs e)
         {
             XmlDocument xd = new XmlDocument();

             // 序列化赋值对象
             List<Tables> allTable = new List<Tables>();
             //Tables getTable = new Tables();
             //ColumnsItems columnItem = new ColumnsItems();

             // 读取字段信息
             int i = dataGridView2.RowCount-;
             for (int j = ; j < i;j++)
             {
                 ////
                 Tables getTable = new Tables();
                 ColumnsItems columnItem = new ColumnsItems();
                 ///
