有没有可能在没有后台工作者的情况下制作一个简单的C#字幕进度条？

using System;
using System.Windows.Forms;

namespace SubtitleProgressBar
{
    public partial class MainForm : Form
    {
        private Timer timer;
        private int maxProgress = 100;
        private int currentProgress = 0;

        public MainForm()
        {
            InitializeComponent();
        }

        private void MainForm_Load(object sender, EventArgs e)
        {
            progressBar.Minimum = 0;
            progressBar.Maximum = maxProgress;
            progressBar.Value = currentProgress;

            timer = new Timer();
            timer.Interval = 1000; // 设置定时器的间隔时间为1秒
            timer.Tick += Timer_Tick;
            timer.Start();
        }

        private void Timer_Tick(object sender, EventArgs e)
        {
            // 更新字幕进度条的值
            currentProgress++;
            progressBar.Value = currentProgress;

            if (currentProgress >= maxProgress)
            {
                // 达到最大值后停止定时器
                timer.Stop();
            }
        }
    }
}
