推荐答案

wajans写道:

System.IO.FileInfo targetfile = new System.IO.FileInfo(anchor.HRef);

如果有人入侵HTTP请求，他们可能会发回任意文件名(这将使他们可以访问您网站上几乎所有的文件，例如web.config).

If somebody hacks an HTTP request, they can potentially send back an arbitrary file name (which would give them access to pretty much any file on your website, such as the web.config).

Response.ContentType "application/octet-stream"

祝你好运！
