本文详细介绍了如何使用C#的XMLSerializer类进行对象的序列化和反序列化操作，包括如何创建序列化器，序列化对象到XML字符串，以及从XML字符串中反序列化回对象，同时探讨了序列化过程中的注意事项和常见问题。

/* The XmlRootAttribute allows you to set an alternate name
   (PurchaseOrder) of the XML element, the element namespace; by
   default, the XmlSerializer uses the class name. The attribute
   also allows you to set the XML namespace for the element.  Lastly,
   the attribute sets the IsNullable property, which specifies whether
   the xsi:null attribute appears if the class instance is set to
   a null reference. */
