List names of all Text files from a Directory and SubDirectories using .NET 4.0

Tweet

The .NET Directory.GetFiles as well as the new Directory.EnumerateFiles (.NET 4.0 only) method has made it extremely easy to read file names with paths, that match a specified search pattern in the specified directory and subdirectories. Here’s how to search and list the names of all Text Files in a Directory as well as its SubDirectories:

C#

static void Main(string[] args)
{
    try
    {
        string dirname = @"C:\Visual Studio 2010";
        var txtFiles = Directory
                            .GetFiles(dirname,
                                "*.txt", SearchOption.AllDirectories)
                            .Select(nm => Path.GetFileName(nm));;
        foreach (string filenm in txtFiles)
        {
            Console.WriteLine(filenm);
        }
    }
    catch (Exception ex)
    {
        Console.WriteLine(ex.Message);
    }

    Console.ReadLine();
}

VB.NET (Converted Code)

Sub Main()
    Try
        Dim dirname As String = "C:\Visual Studio 2010"
        Dim txtFiles = Directory.GetFiles(dirname, "*.txt", SearchOption.AllDirectories).Select(Function(nm) Path.GetFileName(nm))
        For Each filenm As String In txtFiles
            Console.WriteLine(filenm)
        Next filenm
    Catch ex As Exception
        Console.WriteLine(ex.Message)
    End Try

    Console.ReadLine()
End Sub
