如何在一个文件夹中枚举以获取ASP.NET MVC网站中的所有文件名？

Question

How can I see all the images ( *.jpg and *.png ) in a folder, in my website?

All I can give is the location of the folder, but that is relative.

eg. ~/Images/Uploaded or /Images/Uploaded .

cheers :)

Answer 1

It sounds like you want:

var files = Directory.GetFiles(Server.MapPath(path));

In other words:

• Use MapPath to get from the web path to the file system path
• Use Directory.GetFiles to find files on the file system

Answer 2

Jon beats me to it but it may be worth mentioning the overload that takes a search pattern:

string[] files = Directory.GetFiles(Server.MapPath(path), "*.png"); 

You'll need to mix the results for the 2 image types.

不确定要执行什么操作，但首先需要使用HttpContext.Current.Server.MapPath将相对路径解析为“真实路径”，有关示例，请参见http://www.dotnetperls.com/mappath
