如何在完成后清空我的进度条

Question

如果我点击按钮它的加载如此之快，我怎么能将我的progressBar值设置为0？

我的代码是

 private void button1_Click(object sender, EventArgs e)
    {
        int i;
        progressBar1.Minimum = 0;
        progressBar1.Maximum = 100;

        for (i = 0; i <= 100; i++)
        {
            progressBar1.Value = i;

            if (progressBar1.Value == 100)
            {
              progressBar1.Value = 0;                    
            }
            Refresh();
        }
    }

您的代码完全符合您的要求。 您可以添加睡眠以查看内容。

    private void button1_Click(object sender, EventArgs e)
        {
            if(IWantToClearTheProgressbarBeforeWork == true)
                progressBar1.Value = 0;

            int i;
            progressBar1.Minimum = 0;
            progressBar1.Maximum = 100;

            for (i = 0; i <= 100; i++)
            {
                progressBar1.Value = i;
                Thread.Sleep(100);    // only for testing. Blocks your thread.
            }

            if(IWantToClearTheProgressbarImediatelyAfterWorkIsDone == true)
                progressBar1.Value = 0;
        }

这是什么意思？

private async void button1_Click(object sender, EventArgs e)
    {


        int i;
        progressBar1.Minimum = 0;
        progressBar1.Maximum = 100;

        for (i = 0; i <= 100; i++)
        {
            progressBar1.Value = i;
        }

        await Task.Delay(2000);
        if (progressBar1.Value == 100)
        {
            progressBar1.Value = 0;
        }

    }

• 编辑它现在将等待2秒，直到它将其设置为空，这样您就可以看到进度条增加到100。
