如何彻底删除TFS上的团队项目

最近在进行TFS的测试，在TFS服务器上建立了很多项目，发现在TeamExplorer中，只能移除团队项目，这种移除，只是将项目从当前TeamExplorer项目列表中删除，下一次Connect到TFS服务器时，或者刷新一下，就会看到项目依然存在。最后发现，必须使用命令行的方式来删除项目，具体使用方法如下：1、微软提供了一个删除工具，位于C:\ProgramFiles\MicrosoftVisualStudio9\Common7\IDE\目录下，名为TFS

以一种"廉价"的方式获取页面的标题(downmoon)

有朋友问到：“我需要得到一个webpage的title，因为这个title一般都比较靠前，只要取得html的前面少量内容就可以了。因为要取得很多个页面的title,如果下载整个htmlcode，肯定比较浪费时间。.net好像没有现成的类可以干这件事情(取得部分html)，我应该如何去实现？”一种比较"廉价"(即较小成本条件下)的解决思路：第一步：取出含有页面title部分的最小集合。这是“廉价”的关键！第二步：用正则表达式取出和</title</span>
