How to Get All Files Available in a Directory By C#

This post shows an example of listing name of all files with extension, available in a folder. We need to import System.IO namespace in our program and Directory.GetFiles() method helps you to get the list of all files available in the specified folder.

For example, we take a folder “Sample Data” in D drive which contains csv files as shown in below snap.

In order to list all the files available in this folder we write the below given C# program.

using System;
using System.IO;

namespace DirectoryExample
{
    class Program
    {
        static void Main(string[] args)
        {
            string path = @"D:\Sample Data\";
            
            string[] fileList = Directory.GetFiles(path);

            foreach (string fl in fileList)
            {
                FileInfo fi = new FileInfo(fl);
                Console.WriteLine(fi.Name);
            }

            Console.Read();
        }
    }
}

Output:

Sample_CSV_1.csv

Sample_CSV_2.csv

Sample_CSV_3.csv

Sample_CSV_4.csv

In the above C# code, Directory.GetFiles() method returns the list of files on path “D:\Sample Data\” and stores in fileList array and then by the help of Name property of object of FileInfo, we iterate to all file names printing by foreach loop.
