How to get only filenames within a directory using c#?

Question

When I use the line of code as below , I get an string array containing the entire path of the individual files .

private string[] pdfFiles = Directory.GetF         


        

Answer 1

You can use the method Path.GetFileName(yourFileName); (MSDN) to just get the name of the file.

Answer 2

You can use Path.GetFileName to get the filename from the full path

private string[] pdfFiles = Directory.GetFiles("C:\\Documents", "*.pdf")
                                     .Select(Path.GetFileName)
                                     .ToArray();

EDIT: the solution above uses LINQ, so it requires .NET 3.5 at least. Here's a solution that works on earlier versions:

private string[] pdfFiles = GetFileNames("C:\\Documents", "*.pdf");

private static string[] GetFileNames(string path, string filter)
{
    string[] files = Directory.GetFiles(path, filter);
    for(int i = 0; i < files.Length; i++)
        files[i] = Path.GetFileName(files[i]);
    return files;
}

Answer 3

You can simply use linq

Directory.EnumerateFiles(LoanFolder).Select(file => Path.GetFileName(file));

Note: EnumeratesFiles is more efficient compared to Directory.GetFiles as you can start enumerating the collection of names before the whole collection is returned.

There are so many ways :)

1st Way:

string[] folders = Directory.GetDirectories(path, "*", SearchOption.TopDirectoryOnly);
string jsonString = JsonConvert.SerializeObject(folders);

2nd Way:

string[] folders = new DirectoryInfo(yourPath).GetDirectories().Select(d => d.Name).ToArray();

3rd Way:

string[] folders = 
    new DirectoryInfo(yourPath).GetDirectories().Select(delegate(DirectoryInfo di)
    {
        return di.Name;
    }).ToArray();

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace GetNameOfFiles
{
    public class Program
    {
        static void Main(string[] args)
        {
           string[] fileArray = Directory.GetFiles(@"YOUR PATH");
           for (int i = 0; i < fileArray.Length; i++)
           {

               Console.WriteLine(fileArray[i]);
           }
            Console.ReadLine();
        }
    }
}

Answer 6

You could use the DirectoryInfo and FileInfo classes.

//GetFiles on DirectoryInfo returns a FileInfo object.
var pdfFiles = new DirectoryInfo("C:\\Documents").GetFiles("*.pdf");

//FileInfo has a Name property that only contains the filename part.
var firstPdfFilename = pdfFiles[0].Name;
