自定義對象vs字符串

string  objectTostring(object obj)
  {
   using (MemoryStream ms = new MemoryStream())
   {
   XmlSerializer ss=new XmlSerializer(obj.GetType());
   ss.Serialize(ms,we);
   return System.Text.Encoding.UTF8.GetString(ms.GetBuffer());
   }
  }
  //WELL是可序列化的自定義對象

  WELL stringToobject(string ss)
  {
   using(System.IO.MemoryStream ms=new MemoryStream( System.Text.Encoding.UTF8.GetBytes(ss)))
   {
   XmlSerializer xs=new XmlSerializer(typeof(WELL));
   return  (WELL)xs.Deserialize(ms);
   }
  }
