Question

我试图以进度条进度的特定增量进行声音播放。进度条的最大值为80，由一个间隔为100的计时器控制（因此总持续时间为8秒）。在第一种情况下声音播放是因为80/16 = 5这是一个整数，但没有其他播放。如何将进度条值转换为double？或者甚至是正确的轨道？谢谢！

            if (checkBox1.Checked && progressBar1.Value == (progressBar1.Maximum * (1/16)))
                hiphopkick.Play();
            if (checkBox1.Checked && progressBar1.Value == (progressBar1.Maximum * (2 / 16)))
                hiphopkick.Play();
            if (checkBox1.Checked && progressBar1.Value == (progressBar1.Maximum * (3 / 16)))
                hiphopkick.Play();
            if (checkBox1.Checked && progressBar1.Value == (progressBar1.Maximum * (4 / 16)))
                hiphopkick.Play();
            if (checkBox1.Checked && progressBar1.Value == (progressBar1.Maximum * (5 / 16)))
                hiphopkick.Play();
            if (checkBox1.Checked && progressBar1.Value == (progressBar1.Maximum * (6 / 16)))
                hiphopkick.Play();
            if (checkBox1.Checked && progressBar1.Value == (progressBar1.Maximum * (7 / 16)))
                hiphopkick.Play();
            if (checkBox1.Checked && progressBar1.Value == (progressBar1.Maximum * (8 / 16)))
                hiphopkick.Play();
            if (checkBox1.Checked && progressBar1.Value == (progressBar1.Maximum * (9 / 16)))
                hiphopkick.Play();
            if (checkBox1.Checked && progressBar1.Value == (progressBar1.Maximum * (10 / 16)))
                hiphopkick.Play();
            if (checkBox1.Checked && progressBar1.Value == (progressBar1.Maximum * (11 / 16)))
                hiphopkick.Play();
            if (checkBox1.Checked && progressBar1.Value == (progressBar1.Maximum * (12 / 16)))
                hiphopkick.Play();
            if (checkBox1.Checked && progressBar1.Value == (progressBar1.Maximum * (13 / 16)))
                hiphopkick.Play();
            if (checkBox1.Checked && progressBar1.Value == (progressBar1.Maximum * (14 / 16)))
                hiphopkick.Play();
            if (checkBox1.Checked && progressBar1.Value == (progressBar1.Maximum * (15 / 16)))
                hiphopkick.Play();
            if (checkBox1.Checked && progressBar1.Value == (progressBar1.Maximum * (16 / 16)))
                hiphopkick.Play();

首先使用小数，而不是双倍。

Binary floating point and .NET

第二，当你划分两个整数时，结果是int。所以12/16 = 0。为了使它正常工作，你应该这样写：

var decimalRes = progressBar1.Maximum * (13 / (decimal)16);

如何将进度条的值更改为double？
