getting all the files with extension jpg and png

Question

getting all the files with extension jpg and png

Anjali Agarwal 1,531

I am trying to get the latest files from a directory. I have the LINQ statement that gets all the files:

    var myFile = (from f in di.GetFiles("*.jpg", "*.png")
                              orderby f.LastWriteTime descending
                              select f).First();

The issue is, its getting all the files that has upper case "JPG" and no .png files. How can i get all the lower case "*.jpg" and *.png" files from a directory.

To get all files, remove the .First(). However, it is not clear what is di and GetFiles.

Windows files are case-insensitive.

Hi @Anjali Agarwal , Welcome to Microsoft Q&A,

You can compare file extensions using the String.Equals method and specify StringComparison.OrdinalIgnoreCase to ignore case.

using System;
using System.IO;
using System.Linq;

namespace xxx
{
    internal class Program
    {
        static void Main(string[] args)
        {
            string directoryPath = @"C:\Users\Administrator\Desktop\";
            DirectoryInfo di = new DirectoryInfo(directoryPath);

            try
            {
                var myFiles = (from f in di.GetFiles()
                               where f.Extension.Equals(".jpg", StringComparison.OrdinalIgnoreCase) || f.Extension.Equals(".png", StringComparison.OrdinalIgnoreCase)
                               orderby f.LastWriteTime descending
                               select f).ToList();

                if (myFiles.Any())
                {
                    Console.WriteLine("Matching files found:");
                    foreach (var file in myFiles)
                    {
                        Console.WriteLine($"  {file.FullName}");
                    }
                }
                else
                {
                    Console.WriteLine("No matching files found.");
                }
            }
            catch (Exception ex)
            {
                Console.WriteLine($"An error occurred: {ex.Message}");
            }
            Console.ReadLine();
        }
    }
}
