xsd文件可以用来校验欲载入文件的格式，
利用XmlSerializer的Deserialize方法将xml文件还原为Settings格式的对象状态

1XmlSerializer xs=new XmlSerializer(typeof(Settings));
2                FileStream fs = new FileStream("../../XMLFile1.xml",FileMode.Open);
3                Settings settings = (Settings)xs.Deserialize(fs);

Settings类还可以改进，减少到３个类，利用[XmlArrayItem(ElementName="")]和[XmlArray(ElementName="")]标记如下：

  1using System;
  2using System.Collections.Generic;
  3using System.Text;
  4
  5using System.Xml.Serialization;

  7namespace DBSchema2Doc
