/// 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)換也可以傳送)
/// xml解決了在多層架構(gòu)中數(shù)據(jù)傳輸?shù)膯?wèn)題,比如說(shuō)在客戶端可以用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
/// 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),然后客戶端用
/// 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.
/// 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最好不要用遠(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,
