how to combine pdf files into one file, in a directory I have some pdf files that I want to combine into 1 file

I use the following code:

VB
  Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim filePaths As String() = System.IO.Directory.GetFiles(path)
     
        For Each fileName As [String] In filePaths
            Dim targetFolder As String = path
            Dim fi As New System.IO.FileInfo(fileName)
            'fi.CopyTo(System.IO.Path.Combine(path, (fi.Name) & ".pdf"), True)
            Label1.Text = filePaths.Length
            alList.Add(fileName)
        Next
        CombineReport(alList, path)
    End Sub

    Public Shared Function CombineReport(ByVal pdfFiles As IList, ByVal pdfFile As String) As String
        Try
            Dim sb As New System.Text.StringBuilder()
            For Each o As Object In pdfFiles
                sb.Append(o.ToString())
                sb.Append(" ")
            Next
            sb.AppendFormat("cat output {0} allow printing dont_ask", pdfFile)
            System.Diagnostics.Process.Start("C:\WINDOWS\system32\pdftk", sb.ToString()).WaitForExit()
                        
            Return pdfFile
