用C#做个简单的计时器(秒表功能)

 先在窗口中加入一个计时器控件:(timer1)用于触发计时;一个Label控件:(bable1)用于显示时间;两个按钮:(btnStar)用于开始/停止计时,(btnClear)用于计时器清零。

        声明一个整型变量:t,用于获取毫秒,然后在窗口代码中加入以下代码:


       
        private int t = 0;
               
        void MainFormLoad(object sender, System.EventArgs e)
        {
            this.timer1.Enabled = false;
            this.timer1.Interval = 1;
        }
           
        //计时函数
        public string GetAllTime(int time)  
          {
            string hh, mm, ss, fff;
               
              int f = time%100; // 毫秒  
            int s = time/100; // 转化为秒
            int m = s/60;     // 分
            int h = m/60;     // 时
                  s = s%60;     // 秒
       
                  //毫秒格式00
                  if(f<10)
                  {
                      fff = "0" + f.ToString();
                  }
                  else
                  {
                      fff = f.ToString();
                  }
                 
                  //秒格式00
                  if(s<10)
                  {
                      ss = "0" + s.ToString();
                  }
                  else
                  {
                      ss =  s.ToString();
                  }
                 
                  //分格式00
                  if(m<10)
                  {
                      mm = "0" + m.ToString();
                  }
                  else
                  {
                      mm = m.ToString();
                  }
                 
                  //时格式00
                  if(h<10)
                  {
                      hh = "0" + h.ToString();
                  }
                  else
                  {
                      hh = h.ToString();
                  }
             
              //返回 hh:mm:ss.ff           
              return hh + ":" + mm + ":" + ss + "." + fff;
          }
       
        //开始计时按钮单击事件
        void BtnOKClick(object sender, System.EventArgs e)
        {
            if(timer1.Enabled == false)
            {
                this.btnOK.Text = "停止计时";
                this.timer1.Enabled = true;
            }
            else
            {
                this.btnOK.Text = "开始计时";
                this.timer1.Enabled = false;
            }
        }
   
        //时钟控件事件
        void Timer1Tick(object sender, System.EventArgs e)
        {           
            t = t + 1;//得到总的毫秒数  
              this.label1.Text = GetAllTime(t);
        }
   
        //计时器清零
        void BtnClearClick(object sender, System.EventArgs e)
        {
            t = 0;
            //如何正在计时,则先停止再清零,否则直接清零
            if(this.timer1.Enabled == true)
            {
                this.BtnOKClick(sender,e);
                label1.Text = GetAllTime(t);
            }
            else
            {
                label1.Text = GetAllTime(t);
            }
           
        }
