Wypisywanie tekstu z terminalu w richtextbox

Napisalem program w pythonie i go skompilowalem do exe. Pierwszy raz cos takiego robie zeby tekst z terminala miec w aplikacji. Problem jest taki ze aplikacja(terminal) sie uruchamia i nie przechwytuje tekstu do richtextbox. Pierwszy raz cos takiego robie i teraz jak jest to sie uruchamia i nie wypisuje. Ale jak juz chce przez backgroundworkera to juz wgl nic nie rusza.

    public partial class Form1 : Form

        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {

            ProcessStartInfo startInfo = new ProcessStartInfo();
            startInfo.FileName = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "BC.exe");
            startInfo.UseShellExecute = false;
            startInfo.RedirectStandardOutput = true;
         //   startInfo.CreateNoWindow = true; 

            Process process = new Process();
            process.StartInfo = startInfo;
            process.EnableRaisingEvents = true;

            StringBuilder outputBuilder = new StringBuilder();

            process.OutputDataReceived += (o, ee) =>
            {
                if (ee.Data != null)
                {
                    outputBuilder.AppendLine(ee.Data);
                    // update RichTextBox control with the new output
                    richTextBox1.Invoke((MethodInvoker)delegate
                    {
                        richTextBox1.AppendText(ee.Data + Environment.NewLine);
                    });
                }
            };

            process.Start();
            process.BeginOutputReadLine();
            process.WaitForExit();
            //backgroundWorker1.RunWorkerAsync();
        }
        private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
        {
            ProcessStartInfo startInfo = new ProcessStartInfo();
            startInfo.FileName = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "BC.exe");

            startInfo.UseShellExecute = false;
            startInfo.RedirectStandardOutput = true;
            //startInfo.CreateNoWindow = true;

            Process process = new Process();
            process.StartInfo = startInfo;
            process.EnableRaisingEvents = true;

            StringBuilder outputBuilder = new StringBuilder();

            process.Start();

            while (!process.StandardOutput.EndOfStream)
            {
                string line = process.StandardOutput.ReadLine();
                outputBuilder.AppendLine(line);
                backgroundWorker1.ReportProgress(0, line);
            }

            process.WaitForExit();
        }

        private void backgroundWorker1_ProgressChanged(object sender, ProgressChangedEventArgs e)
        {
            string line = (string)e.UserState;
            richTextBox1.AppendText(line + Environment.NewLine);
        }
    }
}

Dobra cos ruszylo. Zrobilem cos takiego.

        private void button1_Click(object sender, EventArgs e)
        {
            backgroundWorker1.RunWorkerAsync();
        }  

        private void backgroundWorker1_DoWork_1(object sender, DoWorkEventArgs e)
        {
            ProcessStartInfo startInfo = new ProcessStartInfo();
            startInfo.FileName = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "BC.exe");
            startInfo.UseShellExecute = false;
            startInfo.RedirectStandardOutput = true;

            Process process = new Process();
            process.StartInfo = startInfo;
            process.EnableRaisingEvents = true;

            StringBuilder outputBuilder = new StringBuilder();

            process.OutputDataReceived += (o, ee) =>
            {
                if (ee.Data != null)
                {
                    outputBuilder.AppendLine(ee.Data);
                    // update RichTextBox control with the new output
                    richTextBox1.Invoke((MethodInvoker)delegate
                    {
                        richTextBox1.AppendText(ee.Data + Environment.NewLine);
                    });
                }
            };

            process.Start();
            process.BeginOutputReadLine();
        }
    }

Ale wypisuje dopiero do richtextbox jak zatrzymie konsole.
