        {
            Process proc = null;
            try
            {
                string batDir = string.Format(@"D:\");
                proc = new Process();
                proc.StartInfo.WorkingDirectory = batDir;
                proc.StartInfo.FileName = "testbat.bat";
                proc.StartInfo.CreateNoWindow = false;
                proc.Start();
                proc.WaitForExit();
                MessageBox.Show("Bat file executed !!");
            }
            catch (Exception ex)

what are the steps to attach the bat file? 

I dont get what thıs means...
the above code is to run a bat file on a button click...

you just modify the path...

add the batch file to your solution directory,
Add it to the solution by add existing file
Right click the batch file and select copy always

using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace WindowsFormsApp1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
            label1.Text = "Press Button to Launch Batch";
        }

        private void button1_Click(object sender, EventArgs e)
        {
            Process proc = null;
            try
            {
                string batDir = string.Format(@".\");
                proc = new System.Diagnostics.Process();
                proc.StartInfo.WorkingDirectory = batDir;
                proc.StartInfo.FileName = "hello World.cmd";
                proc.StartInfo.CreateNoWindow = false;
                proc.Start();
                proc.WaitForExit();
                label1.Text="Bat file executed !!";
            }
            catch (Exception ex)
            {
               label1.Text=ex.StackTrace.ToString();
            }
        }
    }

Thanks David, where is the solution directory?

Proof of Concept

right click on a blank spot in the solution explorer and then look near the bottom.. open folder in file explorer or open folder in terminal 

Thanks David, let me give this a try, many thanks for the video this really helps.. 

Thanks to both of you, it did not work, I give up on this... 

I will try to access your drive.. thanks.. 

it did not work, I give up on this... 

what is not working?
what is your current code
and what is the error message...

David, I received the project.. how do I import it into my Vistual Studio 2019?

unzip it , open a project, browse to the folder containing the .sln file and open the .sln file

Perfect, I have it open and it works, however I can't see the pane where it shows the button and then I can view the code..  
Is there a way I can see it for example when I am working on the button itself?

Your form shows you the form (as it will be shown. right click and show code to see the c# code.
double click on the batch file to edit the batch file.
