2.通过bat方式上传

        Dim sw As StreamWriter = New StreamWriter(ftpFileName, False)
        sw.WriteLine("open" + ftpServer)

        sw.WriteLine("cd /scsTEST/")

        sw.WriteLine("put " + fileNamePath)
        sw.WriteLine("quit")
        sw.Flush()
        sw.Close()

        Dim BatCommandLine As String = "ftp -v -n -i -s:" + ftpFileName

        Dim sw2 As StreamWriter = New StreamWriter(ftpBatFileName, False)
        sw2.WriteLine(BatCommandLine)
        sw2.Close()


        Dim p As System.Diagnostics.Process = New System.Diagnostics.Process
        p.StartInfo.FileName = ftpBatFileName
