[RESOLVED] [2008] Copy Multiple Files without a loop

Hi!!

Is it possible to copy multiple files without having to make use of a loop.

Right now the only way I know to copy multiple files is to loop through them like:

vb.net Code:

Dim Files As New List (Of String)
Files.AddRange(OPD.FileNames)
For a as Integer = 0 To Files.Count - 1
     My.Computer.FileSystem.CopyFile(Files(a), "C:\APath\")
Next

Is there a way like:

vb.net Code:

Dim Files As New List (Of String)
Files.AddRange(OPD.FileNames)
My.Computer.FileSystem.CopyMultipleFile(Files, "C:\APath\")

(OPD is an openfiledialog)

You could use cmd.exe to do this

Code:

---

        'copy all files from A Path to B Path
        Dim info As New ProcessStartInfo("cmd.exe", "/C copy C:\APath\* C:\BPath")
        info.UseShellExecute = False
        info.CreateNoWindow = True

        Dim proc As New Process
        proc.StartInfo = info
        proc.Start()

---

Why would you want to though? I dont think it'll be any more efficient, seeing as the harddrive can not read/write from more than one position at a time.
I could be wrong though.

You can do a CopyDirectory() otherwise you're in a loop. I don't see why a loop is a bad thing though. If the .Net Framework provided a way to copy multiple files I'm sure it would use a loop.

Given that OpenFileDialog.FileNames is a String array, what's the List(Of String) for? Why do you need to create a List to loop through when you've already got an array you can loop through?

vb.net Code:

For Each filePath As String In opd.FileNames
    My.Computer.FileSystem.CopyFile(filePath, "C:\APath")
Next

thks.
