【实例简介】自定义web服务器功能，实现了类似iis的功能
【实例截图】
最终浏览器运行的效果如下：

/// 12/29/09 sky: Implemented more robust command line argument parser (CommandLineParser.cs)
/// 12/29/09 sky: Implemented hosts file modification mode allowing this executable to be run in an elevated process
/// to add/remove hosts file entry corresponding to specified hostname, if desired.
/// 12/29/09 sky: Implemented a MVP pattern with service locator and abstract factory for testing and to simplify
/// gui and console with same codebase
/// 01/07/10 sky: removed console view, it was only there to provide a start and stop mechanism. very stupid design flaw
///
/// Issues:
/// FormView.Stop() doesn't seem to kill the server host? works in console.
/// Is not a critical issue yet - starting another server on same port works just fine.
/// I think it may have to do with vshost.exe persistance as killing vs stops it.

小贴士
感谢您为本站写下的评论，您的评论对其它用户来说具有重要的参考价值，所以请认真填写。
- 类似“顶”、“沙发”之类没有营养的文字，对勤劳贡献的楼主来说是令人沮丧的反馈信息。
- 相信您也不想看到一排文字/表情墙，所以请不要反馈意义不大的重复字符，也请尽量不要纯表情的回复。
- 提问之前请再仔细看一遍楼主的说明，或许是您遗漏了。
- 请勿到处挖坑绊人、招贴广告。既占空间让人厌烦，又没人会搭理，于人于己都无利。
