用C把文件轉(zhuǎn)換為XML

1、用C#把文件轉(zhuǎn)換為XMLusing System;using System .Drawing;using System.Collections;using System.ComponentModel;using System.Windows.Forms;using System.IO;using System.XML;namespace MyWindowsIIIIII這個(gè)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(zhuǎn)換成Office文件III把文件轉(zhuǎn)換成xml格式,然后就可以用Web服務(wù),.net Remoting,WinSock等傳送了 （其中后兩者可以不轉(zhuǎn)換也

2、可以傳送）III xml解決了在多層架構(gòu)中數(shù)據(jù)傳輸?shù)膯?wèn)題上匕如說(shuō)在客戶(hù)端 可以用Web服務(wù)獲取服務(wù)器端的office文件，修改后再回傳給服務(wù)器III只要把文件轉(zhuǎn)換成xml格式便有好多方案可以使用了，而 xml具有平臺(tái)無(wú)關(guān)性，你可以在服務(wù)端用.net用發(fā)布web服務(wù)撚后客 戶(hù)端用Ill Java寫(xiě)一段applit小程序來(lái)處理發(fā)送過(guò)來(lái)的文件，當(dāng)然我舉 的例子幾乎沒(méi)有任何顯示意義，它卻給了我們不少的啟示III另外如果你的解決方案是基于多平臺(tái)的，那么他們之間的 交互不要用遠(yuǎn)程應(yīng)用程序接口調(diào)用(RPC),應(yīng)該盡量用基于文檔的交 互，III 比如說(shuō).net 下的 MSMQJ2EE 的 JMQ.IllIII
