Question

我正在制作Q＆amp; A课程，你有15秒的时间来回答一个问题。问题是进度条只填充了90％并转移到下一个问题。我可以把代码放在这里，但我用荷兰语工作，所以也许很难理解。

    private void volgendeVraagFormButton_Click(object sender, EventArgs e)
    {
        //button for going to next question
        vraagFormulierProgressBar.Value = 0;
        vraagFormulierTimer.Start();
    }

    private void vraagFormulierTimer_Tick(object sender, EventArgs e)
    {
        if (vraagFormulierProgressBar.Value < vraagFormulierProgressBar.Maximum)
            vraagFormulierProgressBar.PerformStep();
            //checks if the value is lower than 15 sec(max)
        else
        {      //stops the progress if the 15 secs are over and moves to next question
            vraagFormulierTimer.Stop();
            vraagFormulierProgressBar.Value = 0;
            vraagFormulierTimer.Start();
        }
    }

以下是使用英文变量名称的相同代码：

private void nextQuestionFormButton_Click(object sender, EventArgs e)
{
    //button for going to next question
    questionFormProgressBar.Value = 0;
    questionFormTimer.Start();
}

private void questionFormTimer_Tick(object sender, EventArgs e)
{
    if (questionFormProgressBar.Value <questionFormProgressBar.Maximum)
       questionFormProgressBar.PerformStep();
        //checks if the value is lower than 15 sec(max)
    else
    {      //stops the progress if the 15 secs are over and moves to next question
       questionFormTimer.Stop();
       questionFormProgressBar.Value = 0;
       questionFormTimer.Start();
    }
}

Answer 1

看看这个：Disabling .NET progressbar animation when changing value?
因此，尝试将进度条增加2，然后减1.这应该可以解决动画问题

修改
另外，改变这一行

if (vraagFormulierProgressBar.Value < vraagFormulierProgressBar.Maximum)

到这个

if (vraagFormulierProgressBar.Value + 1 < vraagFormulierProgressBar.Maximum)

编辑2
好的，这次我得到了它。首先，将进度条的最大值设置为300，将间隔设置为1（稍后可以修复时间）。接下来，用以下代码替换计时器滴答功能：

if (progressBar1.Value < progressBar1.Maximum - 1) { progressBar1.Increment(2); progressBar1.Increment(-1); } else { timer1.Stop(); progressBar1.Maximum = 10000; progressBar1.Value = 10000; progressBar1.Value = 9999; progressBar1.Value = 10000; System.Threading.Thread.Sleep(150); progressBar1.Value = 0; progressBar1.Maximum = 300; timer1.Start(); }

对于使用英文名称感到抱歉，我将其从我的测试表单中删除了。无论如何，希望这有帮助！

进度条停在+ -90％
