如何从Visual Studio中的项目/服务器文件夹中获取文件名？

Question

so what i'm trying to do is to get all the file names of all the images that are located in a specific folder in my project or on the server (which is practically the same) in a string array.

I tried with

Directory.GetFiles(Server.MapPath(@"~/_img/_upload/"));

But the array stays empty. Could anyone help me with that?

I'd appreciate the help, thanks in advance!

Answer 1

The below will get all the images into an array (if you already know the directory structure this should help you):

using System.IO;
using System.Linq;

var imagenames = String.Join(", ", Directory.GetFiles(@"C:\yourdirectory", "*.img").Select(filename => Path.GetFileNameWithoutExtension(filename)).ToArray());

Answer 2

In base at your comment, the result you got from this Server.MapPath(@"~/_img/_upload/") is:

C:\\\\Projects\\\\VS12\\_img\\_upload\\\\

The main problem is the @ because in C# means that the string should be used "as is" and not be processed for escape sequences.

Without it, your string value will be: \\\\_img\\\\_upload\\\\
