VB.NET copy files from excel column?

[daveofgv]

I have many files at work that need to be copied from one directory to another. However, I do not need to copy all the files at once.

I get excel sheets with the list of files that need to be copied once a week. So, in the main directory there is about 150.000 files and I only need to copy about 800 at a time.

I need help doing this. I am thinking of having a textbox and an open dialog so I can pick the directory the main files are at - another one where I can choose where they will be copied to.

The problem is the list will be in excel sheet (column A). How do I have vb.net (2008) see the file names in column A and find them and move them?

Right now, I have macros in excel doing the job, however, I have so many things in this excel I need to transfer this part out and into vb.net.

The macro in excel doing the job is:

Sub CopyFiles()

    Dim objFSO As FileSystemObject
    Dim strSourceFolder As String
    Dim strDestFolder As String
    Dim arrMyFiles() As String
    Dim MatchVal As Variant
    Dim Cnt As Long
    Dim i As Long
    Dim LastRow As Long
    
    Application.ScreenUpdating = False
    
    Set objFSO = CreateObject("Scripting.FileSystemObject")
    
   '*****************************************************************
   '*****************************************************************
    '---- This is the only part that you need to change ----
   '*****************************************************************
    'Change the path to the source folder accordingly
    strSourceFolder = "C:\Users\dbush\Desktop\test\"
    
    'Change the path to the destination folder accordingly
    strDestFolder = "C:\Users\dbush\Desktop\teest\"
   '*****************************************************************
   '*****************************************************************
   
   
   
    Call ProcessFolders(objFSO, strSourceFolder, arrMyFiles(), Cnt)
    
    LastRow = Cells(Rows.Count, "A").End(xlUp).Row
    
    For i = 1 To LastRow
        With Application
            MatchVal = .Match(Cells(i, "A").Value, .Index(arrMyFiles, 2, 0), 0)
            'Error's found then put the value specified
            If IsError(MatchVal) Then
                'Cells(i, "B").Value = 1
                Cells(i, "B").Value = ("Not Found")
                'Colors the non-found cell yellow
                Cells(i, "A").Interior.ColorIndex = 6
            Else
            'Add "Duplicate" to already found files
            If objFSO.FileExists(strDestFolder & Cells(i, "A").Value) Then
             Cells(i, "C").Value = "Duplicate"
    Else
            objFSO.GetFile(.Index(arrMyFiles, 1, MatchVal) & "\" & .Index(arrMyFiles, 2, MatchVal)).Copy strDestFolder, False
        End If
                'objFSO.GetFile(.Index(arrMyFiles, 1, MatchVal) & "\" & .Index(arrMyFiles, 2, MatchVal)).Copy strDestFolder
           End If
        End With
    Next i
    
    Application.ScreenUpdating = True
    'Message box when finished
    MsgBox "Dave's Program has Completed...", vbInformation

Can someone please help me with this changing it over to vb.net?

Any help will be very much appreciated.
