如何使用WinForms进度栏？

我建议您看看BackgroundWorker。如果WinForm中的循环如此之大，它将被阻塞，并且您的应用程序看起来像已经死机了。

查看

BackgroundWorker.ReportProgress()

以了解如何将进度报告回UI线程。

例如：

private void Calculate(int i){    double pow = Math.Pow(i, i);}private void button1_Click(object sender, EventArgs e){    progressBar1.Maximum = 100;    progressBar1.Step = 1;    progressBar1.Value = 0;    backgroundWorker.RunWorkerAsync();}private void backgroundWorker_DoWork(object sender, DoWorkEventArgs e){    var backgroundWorker = sender as BackgroundWorker;    for (int j = 0; j < 100000; j++)    {        Calculate(j);        backgroundWorker.ReportProgress((j * 100) / 100000);    }}private void backgroundWorker_ProgressChanged(object sender, ProgressChangedEventArgs e){    progressBar1.Value = e.ProgressPercentage;}private void backgroundWorker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e){    // TODO: do something with final calculation.}
