Question

How can I list folder files? - Console app

Asked by: Dream_G

Dear Experts,

I want to list the .txt files on a specific folder, so for example there is a folder in the path:
c:/test/
and it contain three files : 1.txt, cmd.exe, 2.txt

The idea works like this, set specific path c:/test/ and just list the txt files so the output will be like this:
1.txt
2.txt

Waiting for help from experts, thanks in advance.

Regards.

Check this example using the Dir method

    If Right$(strPath, 1) <> "\" Then strPath = strPath & "\"
    
    If Trim$(Extention) = "" Then

    ElseIf Left$(Extention, 2) <> "*." Then
        Extention = "*." & Extention

    File = Dir$(strPath & Extention)
    Do While Len(File)

You can use DirectoryInfo and FileInfo.

Imports System.IO
 
Public Class Form1
 
    Public Sub ListFiles(ByVal szDirectory As String, ByVal szExtension As String)
 
        Dim DirInfo As New IO.DirectoryInfo(szDirectory)
        Dim FileInfo As IO.FileInfo() = DirInfo.GetFiles(szExtension)
        Dim fInfo As FileInfo
 
        For Each fInfo In FileInfo
            Console.WriteLine(fInfo.Name)
        Next
 
    End Sub
 
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        ListFiles("c:\windows", "*txt")
 
    End Sub
 
End Class

You can use Request Attention option and some moderator do that for you :)
It's important to choose the right zones and even more then one to have quicker answers.
