How to add progressbar when excuting the bat file?

I have c# code below:

private void button2_Click(object sender, EventArgs e)
    {
        string path = "C:\\Users\\Public\\Downloads\\install_ubuntu2";
        string batFileName = path + ".bat";

        using (StreamWriter batFile = new StreamWriter(batFileName))
        {
            batFile.WriteLine("wsl.exe -u root apt update");
            batFile.WriteLine("wsl.exe -u root apt --assume-yes install xwayland");
            batFile.WriteLine("wsl.exe -u root apt --assume-yes install libegl-dev");
            batFile.WriteLine("wsl.exe -u root DEBIAN_FRONTEND=noninteractive apt --assume-yes install lightdm");
            batFile.WriteLine("wsl.exe -u root apt --assume-yes install ubuntu-desktop");
            batFile.WriteLine("wsl.exe -u root wget -O /tmp/install-sg.sh --content-disposition \"https://gist.githubusercontent.com/djfdyuruiry/6720faa3f9fc59bfdf6284ee1f41f950/raw/952347f805045ba0e6ef7868b18f4a9a8dd2e47a/install-sg.sh\"");
            batFile.WriteLine("wsl.exe -u root chmod +x /tmp/install-sg.sh");
            batFile.WriteLine("wsl.exe -u root /tmp/install-sg.sh && rm /tmp/install-sg.sh");
            batFile.WriteLine("wsl.exe -u root sed -i 's/240/3/g' /etc/genie.ini");
            batFile.WriteLine("wsl.exe --shutdown");
            batFile.WriteLine("wsl whoami > test1.txt");
            batFile.WriteLine("set /P Var=<test1.txt ");
            batFile.WriteLine("Set Var1=/home/%Var%/.bashrc");
            batFile.WriteLine("wsl.exe -u root echo \"genie -i\" ^>^> \"%Var1%\"");
            batFile.WriteLine("wsl.exe -u root echo \"genie -c Xwayland & \" ^>^> \"%Var1%\"");
            batFile.WriteLine("wsl.exe -u root echo \"timeout 20\" ^>^> \"%Var1%\"");
            batFile.WriteLine("wsl.exe -u root echo \"genie -c gnome-session & \" ^>^> \"%Var1%\"");

            batFile.WriteLine("powershell -Command \"Install-PackageProvider -Name NuGet -MinimumVersion 2.8.5.201 -Force -Scope CurrentUser\"");
            batFile.WriteLine("powershell -Command \"Set-ExecutionPolicy RemoteSigned -Scope CurrentUser\"");
            batFile.WriteLine("powershell -Command \"Install-Module VirtualDesktop -Force -Scope CurrentUser\"");
            batFile.WriteLine("powershell -Command \"Import-Module VirtualDesktop\"");
            batFile.WriteLine("powershell -Command \"New-Desktop\"");
            //batFile.WriteLine("PAUSE");
        }

        ProcessStartInfo processStartInfo = new ProcessStartInfo("cmd.exe", "/c " + batFileName);
        processStartInfo.UseShellExecute = true;
        processStartInfo.CreateNoWindow = true;
        processStartInfo.WindowStyle = ProcessWindowStyle.Normal;

        Process p = new Process();
        p.StartInfo = processStartInfo;
        p.Start();
        p.WaitForExit();

        File.Delete(batFileName);
    }

I have to know to cmd execution progress and add a progressbar.

The progressbar's code is enter link description here.

How to achieve that?

Thank you very much.

In Windows Forms you could do something like this (In this version without the use of IProgress):

    void StartButton_Click(object sender, EventArgs e)
    {
        var listOfCommands = InitializeListOfCommands();
        var numberOfItems = listOfCommands.Count();

        for (int i = 0; i < numberOfItems; i++)
        {
            RunCommand(listOfCommands[i].Cmd, listOfCommands[i].Parameter);
            ProgressProgressBar.Value = (i + 1) * 100 / numberOfItems;
        }
    }

    List<(string Cmd, string Parameter)> InitializeListOfCommands()
    {
        return new List<(string Cmd, string Parameter)>()
        {
            ("wsl.exe", "-u root apt update"),
            ("wsl.exe", "-u root apt --assume-yes install xwayland"),
            // next commands
        };
    }

    void RunCommand(string cmd, string arguments)
    {
        ProcessStartInfo processStartInfo = new ProcessStartInfo(cmd, arguments);
        processStartInfo.UseShellExecute = true;
        processStartInfo.CreateNoWindow = true;
        processStartInfo.WindowStyle = ProcessWindowStyle.Normal;

        Process p = new Process();
        p.StartInfo = processStartInfo;
        p.Start();
        p.WaitForExit();
    }

Keep in mind:

• the example above is running synchronously
• keep an eye on the error handling when Process returns an errorlevel
