private void Form1_Load(object sender, EventArgs e)
{
this.timer1.Start();
this.timer1.Interval = 1000;
}
int num = 0;
double numstep = 100.0 / 232;
private void timer1_Tick(object sender, EventArgs e)
{
num=Convert.ToInt32( num + numstep);
if (num>=100)
{
num = 100;
}
this.progressBar1.Value =num;

}
这里采用了“曲线救国 ”的策略，但是也实现了功能。。。。。

追问

我也是这样做的。
但是 numstep是个浮点数 把num+numstep 转化为整形，要丢失精度....
比如进度条表示播放的进度。这样做的结果是，已经播放完成了，但是进度条还没走完.....

private void Form1_Load(object sender, EventArgs e)
{
this.timer1.Start();
this.timer1.Interval = 1000;

this.progressBar1.Maximum = 232;//设定你需要的秒数
}
int num = 0;
private void timer1_Tick(object sender, EventArgs e)
{
this.progressBar1.Value =num++%232;//如果超出232那么重新从0开始
this.label1.Text = num.ToString();
}
我们忘了它最重要的一个属性，就是进度条的最大值 。。。这样就可以了，相比以前更简单
