进度条

Question

WinForm C#:
我想单击Button让窗体中的进度条在150秒内完成由满到空.实现倒数的作用.

Answer 1

  private void button1_Click(object sender, EventArgs e)
        {
            progressBar1.Maximum = 150;
            progressBar1.Value = 150;
            timer1.Interval = 1000;
            timer1.Tick += new EventHandler(timer1_Tick);
            timer1.Enabled = true;
        }        void timer1_Tick(object sender, EventArgs e)
        {
            progressBar1.Value--;
            if (progressBar1.Value == 0) timer1.Enabled = false;
        }

Answer 2

设定150毫秒 条.Value-=Vlaue一次

Answer 3

将进度条分割为150份，每秒让进度条递增一份，到最后一次的时候让进度条100%，用一个Timer控件来做。这就是思路。private void button1_Click(object sender, EventArgs e)
        {
            progressBar1.Maximum = 150;
            progressBar1.Value = 150;
            timer1.Interval = 1000;
            timer1.Tick += new EventHandler(timer1_Tick);
            timer1.Enabled = true;
        }        void timer1_Tick(object sender, EventArgs e)
        {
            progressBar1.Value--;
            if (progressBar1.Value == 0) timer1.Enabled = false;//进度条为0的时候停止倒计时
        }

Answer 4

 private void Returnbutton_Click(object sender, EventArgs e)
        {
            Shitimer.Enabled = true;
            progressBar1.Value = 150;
            Shitimer.Tick += new EventHandler(Shitimer_Tick);
        }        private void Shitimer_Tick(object sender, EventArgs e)
        {
            progressBar1.Value--;
            if (progressBar1.Value == 0)
            {
                Shitimer.Enabled = false;
            }
        }谢谢!
