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
1 XmlSerializer 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：
