  //定义purchaseorder类型的数组对象obj, 设置其数组长度为2，
  //    并在其中保存了用户要序列化的数据。
  purchaseorder obj = new purchaseorder();
  obj.itemsorders = new item[2];
  obj.itemsorders[0] = new item();
  obj.itemsorders[0].itemid = "first";
  obj.itemsorders[0].itemprice = 500.25m;

  obj.itemsorders[1] = new item();
  obj.itemsorders[1].itemid = "second";
  obj.itemsorders[0].itemprice = 66.88m;

  //创建一个文件流对象stream，指向文件myfile.bin
  iformatter formatter = new binaryformatter();
  stream stream = new filestream("d://myfile.bin", filemode.create,
  fileaccess.write, fileshare.none);

  //通过formatter对象以二进制格式将obj对象序列化后到文件myfile.bin中
  formatter.serialize(stream,obj);
  stream.close();
}

//定义两个可序列化的类purchaseorder 和item
[serializable]
public class purchaseorder
{
  public item [] itemsorders;
}

[serializable]
public class item
{
  public string itemid;
  public decimal itemprice;
