How to use any dos command inside a VB .NET?

[Worrow]

I tried to call "del *.bak" inside my program with process.start. However, since del is not a file so it is not possible to use process.start to call it. I know there are other ways to do the same thing but I just want to use dos command. Any idea how?

Thanks in advance.

Have your program create a batch file that contains all the DOS
commands you want to execute. Then use Process.Start() to
run the batch.

Forget about dos and batch file command buddy Here is vb.net code for you.

Dim fs() As String, i As Integer
fs = Directory.GetFiles(Directory.GetCurrentDirectory, "*.bat")

For i = 0 To UBound(fs)
     File.Delete(fs(i))
Next

if you want to use the Dos method of deleting files from a folder, heres a quick sample i knocked up for you ...

        Dim pr As Process
        Dim args As New ProcessStartInfo("cmd.exe")
        With args
            .RedirectStandardInput = True
            .RedirectStandardOutput = True
            .UseShellExecute = False
            .WindowStyle = ProcessWindowStyle.Normal
        End With
        pr = Process.Start(args)
        /// now lets delete all files with a .txt extension from the folder C:\testing\
        /// you would obviously use *.bak instead of *.txt here ...
        pr.StandardInput.WriteLine("del C:\testing\*.txt" & Convert.ToChar(13)) /// chr(13) being Enter key.
        pr.CloseMainWindow()

hope it helps

Hi! Your technique is cool buddy, but in this situation is different. I think to put an elephant into a refrigerator, just open the door and put it in. So...

Process.Start("c:\windows\system32\cmd.exe /c del *.bat")

dragon4spys method is the best one.

[msdn]System.IO[/msdn] is the best method...
