How to Display Real-time Command Output in a Form Control?

private async void btnExecute_Click(object sender, EventArgs e)
{
    // Get currently selected tab page and controls
    var tabPage = tcExecControl.SelectedTab;
    var commandTextBox = (TextBox)tabPage.Controls[0]; // Assuming command is in the first control
    var argumentsTextBox = (TextBox)tabPage.Controls[1]; // Assuming arguments are in the second control
    var outputTextBox = (TextBox)tabPage.Controls[2]; // Assuming output textbox is the third control

    string command = commandTextBox.Text;
    string arguments = argumentsTextBox.Text;

    try
    {
        // Capture the SynchronizationContext for UI thread updates
        var uiContext = SynchronizationContext.Current;

        // Asynchronously execute the command
        await Task.Run(() =>
        {
            using (var process = new Process())
            {
                process.StartInfo.FileName = command;
                process.StartInfo.Arguments = arguments;
                process.StartInfo.UseShellExecute = false;
                process.StartInfo.RedirectStandardOutput = true;
                process.StartInfo.RedirectStandardError = true; // Redirect error stream as well
                process.Start();

                // Read output line by line
                string line;
                while ((line = process.StandardOutput.ReadLine()) != null)
                {
                    // Update the textbox on the UI thread
                    uiContext.Post(_ => outputTextBox.AppendText(line + Environment.NewLine), null);
                }

                // Read and display error output (if any)
                string errorLine;
                while ((errorLine = process.StandardError.ReadLine()) != null)
                {
                    uiContext.Post(_ => outputTextBox.AppendText("Error: " + errorLine + Environment.NewLine), null);
                }

                process.WaitForExit();
            }
        });
    }
    catch (Exception ex)
    {
        outputTextBox.AppendText($"An error occurred: {ex.Message}{Environment.NewLine}");
    }
}
