WinForm應用程序中實現自動更新功能

編寫人：左丘文

近來在給一客戶實施ECM系統，但他們使用功能並不是我們ECM制造版提供的標准功能，他們要求對系統作一些定制功能，為了避免因程序的bug而帶來頻繁讓用戶更新程序的不良影響，就想給ECM增加一個winform自動更新功能，今天在這里，我想與大家一起分享代碼，在此做個小結，以供參考。有興趣的同學，可以一同探討與學習一下，否則就略過吧。

1、首先我們在這里先分析一下其它程序猿的一些基本情況：

相信有許多程序猿都喜歡用Winform做開發吧？！因為Winform相對Webform而言，優點是，功能更強大，編程更方便.但是它的缺點，就是軟件的安裝及維護是相當麻煩地，要實現軟件更新，需要到客戶端一台一台地升級。

長期以來，廣大程序猿為到底是使用Client/Server，還是使用Browser/Server結構爭論不休，在這些爭論當中,C/S結構的程序可維護性差，布置困難，升級不方便，維護成本高就是一個相當重要的因素。有很多企業用戶就是因為這個原因而放棄使用C/S。然而當一個應用必須要使用C/S結構才能很好的實現其功能的時候，我們該如何解決客戶端的部署與自動升級問題？部署很簡單，只要點擊安裝程序即可，難的在於每當有新版本發布時，能夠實現自動升級。現在好了，我們的目標很簡單，我們希望開發一個與具體應用無關的能夠復用的自動升級系統。下面我為大家提供了一套可復用的用C#實現在線升級。這里分為本地在線升級，也可以利用webservice 在線通過互聯網與軟件開商的服務器在線升級。

2、 實現軟件自動在線升級的原理：

1) 寫三個程序，一個是主程序；兩個是升級程序；所有升級任務都由升級程序完成

原本只需要一個升級程序，但在這里，由於我們另外還涉及到了，在線與軟件供應商服務器更新功能，因此我們這里用到了一個主程序兩個升級程序。

2) 很多人實行的原理是將現有版本與最新版本作比較，發現最新的則提示用戶是否升級，當然也有人用其它屬性比較的，例如：文件大小或者更新日期。我們這里主要利用FileUtil的兩個屬性SHA1File與MD5File來判斷，與服務器之間是否存在版本差異，存在就更新。

3) 我們的程序,剛開始初始版本是我一同事利用了三天時間，大致寫了一個框架出來，我是在他的基礎上，對其進行了完善，如增加了對文件流的壓縮與解壓縮功能，方便進行網絡的傳輸，增加了通過webservices的在線更新功能。並將程序做到通用功能，並嵌套到了我們的ECM系統中。

3、 軟件更新操作界面：

1) 啟動我們的主程序ECM

2) 系統會從數據庫中檢查是否有新版本，點點【否】會直接進入系統，點【是】系統會進入到更新介面：

先擇需要更新的內容，點擊更新，系統會自動更新相關程序。

3) 與軟件供應商服務器在線更新介面：

操作類似於在線本地更新一樣。

具體就需要各位好好的自已去調試了。

4、 更新程序的代碼：

1) 我們的更新程序是以文件流的形式存放在數據庫中，因此我們首先需要為系統數據庫增加相關的表，用於存儲更新文件。
