操作服务器的文件夹复制---SYSTEM.IO中的DIRECTORY类中没有提供吗?

Question

you can write some recursive functions to copy directories as shown here:http://groups.google.com/groups?hl=en&lr=&ie=UTF-8&oe=UTF-8&selm=lRrChWjgCHA.2308%40cpmsftngxa09http://groups.google.com/groups?q=C%23+copy+directory&hl=en&lr=&ie=UTF-8&oe=UTF-8&selm=e4Ty4zorBHA.2520%40tkmsftngp04&rnum=1
or use SHFileOperation API, for example
