总结：这套模版分四步，这样就完成了一个三层建构的网站的大体部分，其它部分可以自行扩充，比如CodeSmith直接生成文件夹目录及文件夹到本地，或是中间要加入接口层等。
要写创建文件夹，及文件，就是一个IO操作，我这里就不写了。。
如果有要扩展的在头部引用
<%@ Import Namespace="System.IO" %>
把方法写在<script runat="template">标签中
比如：写一个方法
public CreatDir()
{
System.IO.DirectoryInfo di = new DirectoryInfo(OutputDirectory);
di.CreateSubdirectory("Domain");
....
}
