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:

 1     [Serializable]
 2     [XmlRoot("Table")]
 3     public class Tables
 4     {
 5         public Tables()
 6         {
 7             Items = new List<ColumnsItems>();
 8         }
 9      
10         /// <summary>
11         /// 新表名称
12         /// </summary>
13         [XmlElementAttribute("NewTableName")]
14         public string NewTableName { get; set; }
15 
16         /// <summary>
17         /// 旧表名称
