用编程方式给IIS里增加MIME类型

最近在搞一个安装程序，其中有一步，是要给iis增加一个新的mime类型.log，好让用户能下载iis的日志。



iis的所有的操作都可以用System.DirectoryServices里的功能完成。mime类型一定也可以。果然，经过一翻寻找，在msdn中找到。原文如下：http://msdn2.microsoft.com/en-us/library/ms525901.aspx

这里面关键一步是引用Active DS IIS Namespace Provider，这样你就能使用IISOle这个命名空间，和IISMimeType 这个类。



实际代码并不复杂，全部在下面，比较简单，就不多解释。
