对于上述XML文件，请在.NET 2005 中用C#对其序列化，因层次结构比较复杂，请各位帮忙。

烦请定义成如下格式，谢谢。
[XmlRootAttribute("PurchaseOrder", Namespace="http://www.cpandl.com",  
  IsNullable = false)]  
  public class PurchaseOrder  
  {  
  public Address ShipTo;  
  public string OrderDate;  
  /* The XmlArrayAttribute changes the XML element name  
  from the default of "OrderedItems" to "Items". */  
  [XmlArrayAttribute("Items")]  
  public OrderedItem[] OrderedItems;  
  public decimal SubTotal;  
  public decimal ShipCost;  
  public decimal TotalCost;  
  }  
   
  public class Address  
  {  
  /* The XmlAttribute instructs the XmlSerializer to serialize the Name  
  field as an XML attribute instead of an XML element (the default  
  behavior). */  
  [XmlAttribute]  
  public string Name;  
  public string Line1;  
   
  /* Setting the IsNullable property to false instructs the  
  XmlSerializer that the XML attribute will not appear if  
  the City field is set to a null reference. */  
  [XmlElementAttribute(IsNullable = false)]  
  public string City;  
  public string State;  
  public string Zip;  
  }
