DirectoryInfo questions.

[TType85]

I'm in the process of making a small intranet site for use in my home. I have ripped all our CD's to MP3's and they are pretty well organized, and i'm trying to automate loading the info I need into a SQL database.

Directory structure is like this

Music
 |----Artist - AlbumName
 |     |--01 - SongName.mp3
 |----Artist - AlbumName
 |     |--01 - SongName.mp3
 |----Etc...

But some of my CD's are multiple disc sets so the structure is like this:

Music
Music
 |----Artist - AlbumName
 |     |--01 - SongName.mp3
 |----Artist - AlbumName
 |     |--CD1
 |     |    |--01 - SongName.mp3
 |     |--CD2
 |     |    |--01 - SongName.mp3
 |----Etc...

Currently I have code using IO.DirectoryInfo & IO.FileInfo pulling the information, but it doesn't work when it comes to the multiple CD ones. My current code reads it to the screen correctly and my database code works perfectly for inserting. What I need is to read sub directories under the current directory. Whats the best way to do that?

  Sub getDirs()
        Dim Dir1 As IO.DirectoryInfo = New IO.DirectoryInfo("\\pvr\c\music")
        Dim dirs As IO.DirectoryInfo() = Dir1.GetDirectories("*")
        Dim diNext As IO.DirectoryInfo
        Dim files As IO.FileInfo()
        Dim filename As IO.FileInfo

            For Each diNext In dirs
                Console.WriteLine(diNext.Name)
                files = diNext.GetFiles("*")
                For Each filename In files
                    Console.WriteLine("      " & filename.Name)
                Next
                Console.ReadLine()
             Next
    End Sub

Make it recursive, that is it calls the sub with in itself.

Good Idea. I've been out of programming for about a year so I'm a bit rusty. Here is my first pass at a non-recursive way of doing it.... It works, but I know it can be optimized a ton.

 Function ReadDirectories() As Boolean
        'declarations
        Dim MainDirectory As IO.DirectoryInfo = New IO.DirectoryInfo(strRootDirectory)
        Dim DirectoryList As IO.DirectoryInfo() = MainDirectory.GetDirectories("*")
        Dim DiNext As IO.DirectoryInfo

        Dim DirectoryChildRoot As IO.DirectoryInfo
        Dim DirectoryChild As IO.DirectoryInfo()
        Dim DiNextChild As IO.DirectoryInfo

        Dim Files As IO.FileInfo()
        Dim FileName As IO.FileInfo

        Try
            For Each DiNext In DirectoryList
                If DiNext.GetDirectories("*").Length > 0 Then
                    DirectoryChildRoot = New IO.DirectoryInfo(DiNext.FullName)
                    DirectoryChild = DirectoryChildRoot.GetDirectories("*")
                    For Each DiNextChild In DirectoryChild
                        Files = DiNextChild.GetFiles
                        For Each FileName In Files
                            Console.WriteLine(FileName.FullName)
                        Next
                    Next
                End If
                Files = DiNext.GetFiles
                For Each FileName In Files
                    'write files
                Next
            Next
            Return True
        Catch ex As Exception
            HandleError(ex)
            Return False
        End Try

    End Function

I have written this sample code, it may help you and may need some tweaks. What it does is getting all folders and files of a directory matching especial extension and writing the results to a text file.

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Me.Cursor = Cursors.WaitCursor
        Dim strwri As New StreamWriter("c:\dir.txt")
        getdir("D:\", ".mp*", strwri)
        strwri.Close()
        Me.Cursor = Cursors.Default
End Sub
Private Sub getdir(ByVal rootdir As String, ByVal ext As String, ByVal sw As StreamWriter)
        Try
            Dim maindir As New DirectoryInfo(rootdir)
            Dim allfiles As FileSystemInfo, fileext, dirs As String
            For Each allfiles In maindir.GetFileSystemInfos()
                If TypeOf allfiles Is DirectoryInfo Then
                    getdir(allfiles.FullName, ext, sw)
                Else
                    fileext = allfiles.Extension
                    If System.Text.RegularExpressions.Regex.IsMatch(fileext, ext.Replace("*", "")) Then
                        dirs += "   " & allfiles.Name + Environment.NewLine
                    End If
                End If
            Next
            If dirs.Length > 0 Then
                sw.WriteLine(CType(allfiles, FileInfo).Directory.FullName)
                sw.WriteLine(dirs)
            End If
        Catch
        End Try
End Sub

BTW, you should import System.IO

Thanks for the help. I'll have to play with the code, tear it apart and put it back together.

I need to learn vb.net I could of done this in about 10min in VB6 :P
