WinForm应用程序中实现自动更新功能
WinForm应用程序中实现自动更新功能
编写人：左丘文

近来在给一客户实施ECM系统，但他们使用功能并不是我们ECM制造版提供的标准功能，他们要求对系统作一些定制功能，为了避免因程序的bug而带来频繁让用户更新程序的不良影响，就想给ECM增加一个winform自动更新功能，今天在这里，我想与大家一起分享代码，在此做个小结，以供参考。有兴趣的同学，可以一同探讨与学习一下，否则就略过吧。
1、 首先我们在这里先分析一下其它程序猿的一些基本情况：
相信有许多程序猿都喜欢用Winform做开发吧？！因为Winform相对Webform而言，优点是，功能更强大，编程更方便.但是它的缺点，就是软件的安装及维护是相当麻烦地，要实现软件更新，需要到客户端一台一台地升级。
长期以来，广大程序猿为到底是使用Client/Server，还是使用Browser/Server结构争论不休，在这些争论当中,C/S结构的程序可维护性差，布置困难，升级不方便，维护成本高就是一个相当重要的因素。有很多企业用户就是因为这个原因而放弃使用C/S。然而当一个应用必须要使用C/S结构才能很好的实现其功能的时候，我们该如何解决客户端的部署与自动升级问题？部署很简单，只要点击安装程序即可，难的在于每当有新版本发布时，能够实现自动升级。现在好了，我们的目标很简单，我们希望开发一个与具体应用无关的能够复用的自动升级系统。下面我为大家提供了一套可复用的用C#实现在线升级。这里分为本地在线升级，也可以利用webservice 在线通过互联网与软件开商的服务器在线升级。
2、 实现软件自动在线升级的原理：
1) 写三个程序，一个是主程序；两个是升级程序；所有升级任务都由升级程序完成
原本只需要一个升级程序，但在这里，由于我们另外还涉及到了，在线与软件供应商服务器更新功能，因此我们这里用到了一个主程序两个升级程序。
2) 很多人实行的原理是将现有版本与最新版本作比较，发现最新的则提示用户是否升级，当然也有人用其它属性比较的，例如：文件大小或者更新日期。我们这里主要利用FileUtil的两个属性SHA1File与MD5File来判断，与服务器之间是否存在版本差异，存在就更新。
3) 我们的程序,刚开始初始版本是我一同事利用了三天时间，大致写了一个框架出来，我是在他的基础上，对其进行了完善，如增加了对文件流的压缩与解压缩功能，方便进行网络的传输，增加了通过webservices的在线更新功能。并将程序做到通用功能，并嵌套到了我们的ECM系统中。
3、 软件更新操作界面：
1) 启动我们的主程序ECM
2) 系统会从数据库中检查是否有新版本，点点【否】会直接进入系统，点【是】系统会进入到更新介面：
先择需要更新的内容，点击更新，系统会自动更新相关程序。
3) 与软件供应商服务器在线更新介面：
操作类似于在线本地更新一样。
具体就需要各位好好的自已去调试了。
4、 更新程序的代码：
1) 我们的更新程序是以文件流的形式存放在数据库中，因此我们首先需要为系统数据库增加相关的表，用于存储更新文件。
