C# Show files in my website
===

Hi how can I show files in my website to download it. I have got code :

    Directory.GetFiles("http://xxx.com/Folder1/Folder2", "*.*")
But it isn't working. I can use it like this :

    Directory.GetFiles(@"C:\Program Files\Folder1\Folder2", "*.*")
How can I use this code for show files in http://xxx.com/Folder1/Folder2 ?
