Reading a Directory//Writing to a Text File?

Hey everyone,

Can someone tell me how I can read the contents of a directory...then insert each file name in that directory into a text file??

The reason is I have like 600 Mp3's and a friends wants them...and I dont want to have to type each one out...so this way it will create a list of the songs and then I can give her that.

Thanks in advance!!

Use DirectoryInfo and FileInfo classes. Very Easy.

Here you go:

Code:

---

private void button1_Click(object sender, System.EventArgs e) {
    DirectoryInfo dir = new DirectoryInfo(@"c:\music");
    StreamWriter stream = new StreamWriter(@"c:\music list.txt");
    foreach(FileInfo f in dir.GetFiles()) {
        stream.WriteLine(f.Name);
    }
    stream.Close();
}

Thanks for the reply...

but I sitll cant get it to work....first thing is I'm doing it in VB.net not C..

But I converted it to this.

Code:

---

Dim Dir As New System.IO.DirectoryInfo("C:\Downloads\Mp3's")
        Dim F As New System.IO.FileInfo("C:\Downloads\Mp3's\New ****\Eminem - Lose Yourself")
              Dim Writer As New System.IO.StreamWriter("C:\New Songs.txt")

        For Each F In Dir.GetFiles
            Writer.WriteLine(F.Name)
        Next
        Writer.Close()

You never posted any code about the fileinfo delcarations and I think that is where my problem is??

So I want to have a list of all the songs that are in "C:\Downloads\Mp3's"

Thanks again.

You could do it the old fashion way and use DOS commands :)

PHP Code:

---

dir *.mp3 > mysongs.txt 


---

oi, dos commands = evil

here you go

VB Code:

Private Sub Find_Mp3(ByVal startDir As String)
        Dim dir As System.IO.DirectoryInfo, file As System.IO.FileInfo
        Dim stream As System.IO.StreamWriter
 
        dir = New System.IO.DirectoryInfo(startDir)
        stream = New System.IO.StreamWriter(startDir & "Music list.txt")
        For Each file In dir.GetFiles
            If file.Extension = ".mp3" Then stream.WriteLine(file.Name)
        Next
        stream.Close()
 
    End Sub

called like such

VB Code:

Find_Mp3("C:\Mp3's\New Found Glory\")

You may like to go to sub directories as well.
Try this:

VB Code:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim outfile As StreamWriter= New StreamWriter("C:\test.txt")
        Me.Cursor.Current = Cursors.WaitCursor
        tree("E:\", outfile)
        outfile.Close()
        Me.Cursor.Current = Cursors.Default
End Sub
 
Private Sub tree(ByVal dr As String, ByVal outfile As StreamWriter)
        Dim maindir As DirectoryInfo = New DirectoryInfo(dr)
        Dim subfd As FileSystemInfo
        outfile.WriteLine(maindir.FullName)
        Try
            For Each subfd In maindir.GetFileSystemInfos
                If TypeOf subfd Is FileInfo Then
                    If subfd.Extension = ".mp3" Then
                        outfile.WriteLine(subfd.Name)
                    End If
                Else
                        tree(subfd.FullName, outfile)
                End If
            Next
        Catch
        End Try
End Sub

Be sure to import System.IO
