In this article, we would like to show you how to list files from directory in C# / .NET.

1. Get files and directories from directory example

Edit

xxxxxxxxxx
 
using System;
using System.IO;
​
public static class Program
{
    public static void Main(string[] args)
    {
        string path = @"C:\Directories";
​
        string[] files = Directory.GetFiles(path);
​
        foreach (string entry in files)
            Console.WriteLine(string.Format("{0,-40}   [FILE]", entry));
    }
}

Output:

xxxxxxxxxx
 
C:\Directories\json.txt                    [FILE]
C:\Directories\screenshot.png              [FILE]
C:\Directories\sound.mp3                   [FILE]
C:\Directories\wallpaper.jpg               [FILE]

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

​
        string[] files = Directory.GetFiles(path, "", SearchOption.AllDirectories);
​
        foreach (string entry in files)
            Console.WriteLine(string.Format("{0,-40}   [FILE]", entry));
