 /// 這個示例演示如何把Office文件編碼為xml文件以及如何把生成的xml文件轉換成Office文件
 /// 把文件轉換成xml格式,然後就可以用web服務,.NET Remoting,WinSock等傳送了(其中後兩者可以不轉換也可以傳送)
 /// xml解決了在多層架構中數據傳輸的問題,比如說在客戶端可以用Web服務獲取服務器端的office文件,修改後再回傳給服務器
 /// 只要把文件轉換成xml格式,便有好多方案可以使用了,而xml具有平台無關性,你可以在服務端用.net用發布web服務,然後客戶端用
 /// Java寫一段applit小程序來處理發送過來的文件,當然我舉的例子幾乎沒有任何顯示意義,它卻給了我們不少的啟示.
 /// 另外如果你的解決方案是基於多平台的,那麼他們之間的交互最好不要用遠程應用程序接口調用(RPC),應該盡量用基於文檔的交互,
 /// 比如說.net下的MSMQ,j2ee的JMQ.
 ///
 /// 示例中設計到好多的類,我並沒有在所有的地方做過多注釋,有不明白的地方請參閱MSDN,這是偶第一個windows程序,有不對的地方
 /// 歡迎各位指導
