ACTUALIZA ** TODAVÍA BUSCANDO UNA RESPUESTA CORRECTA ** Tengo el siguiente código en mi servicio de Windows y quiero ejecutar un archivo por lotes. Quiero que aparezca la ventana del símbolo del sistema para poder ver el progreso

aquí está mi código pero mi código de archivo por lotes no funciona

using System;

using System.IO;

    namespace Watcher
    {
        public partial class Watcher : ServiceBase
        {
            public Watcher()
            {
                InitializeComponent();
            FolderWatcher.Created += FolderWatcher_Created;
            FolderWatcher.Deleted += FolderWatcher_Deleted;
            FolderWatcher.Renamed += FolderWatcher_Renamed;
            }

            protected override void OnStart(string[] args)
            {

                          // Start the child process.
            Process p = new Process();
            // Redirect the output stream of the child process.
            p.StartInfo.UseShellExecute = false;
            p.StartInfo.RedirectStandardOutput = true;
            p.StartInfo.FileName = "C:\\myFile.bat";
            p.Start();
            // Do not wait for the child process to exit before
            // reading to the end of its redirected stream.
            // p.WaitForExit();
            // Read the output stream first and then wait.
            string output = p.StandardOutput.ReadToEnd();
            p.WaitForExit();


            }

            protected override void OnStop()
            {
            }

            private void FolderWatcher_Created(object sender, System.IO.FileSystemEventArgs e)
            {
                TextWriter writer = new StreamWriter("C:\\folder\\FolderLog.txt", true);
                writer.WriteLine(DateTime.Now + " A new folder/file with name " + e.Name + " has been created. ");
                writer.Close();
            }

            private void FolderWatcher_Deleted(object sender, System.IO.FileSystemEventArgs e)
            {
                TextWriter writer = new StreamWriter("C:\\folder\\FolderLog.txt", true);
                writer.WriteLine(DateTime.Now + " A new folder/file with name " + e.Name + " has been deleted. ");
                writer.Close();
            }

            private void FolderWatcher_Renamed(object sender, System.IO.RenamedEventArgs e)
            {
                TextWriter writer = new StreamWriter("C:\\folder\\log.txt", true);
                writer.WriteLine(DateTime.Now + " A new folder/file with name " + e.Name + " has been renamed. ");
                writer.Close();
            }


        }
    }

No ejecuta el archivo por lotes. Soy un novato en .net y C # y no estoy seguro de qué hacer desde aquí. Gracia
