推荐答案

如果要提供文件链接，则需要提供可用于Web的链接.最简单的方法是执行server.mappath("//");然后将文件路径中的内容替换为网站的根URL.然后，只要IIS愿意提供它，您就可以呈现到它的链接.

If you want to provide links to files, you need to provide a link that is web ready. The easiest way is to do server.mappath("//"); and then replace that from the file path with the root URL of your site. Then you can render a link to it, so long as IIS is happy to serve it.
