计时器问题

Question

想做个计时器软件   就是 输入一个时间 然后开始倒计时   可是不知道怎么做  麻烦高手指点下!

Answer 1

class Program
    {
        static void Main(string[] args)
        {
            //dt中存放你的时间,可以把需要的时间转换成一个秒数，这里设定为10秒
            DateTime dt=new DateTime(10);
            long ticks = dt.Ticks;            while (true)
            {
                System.Threading.Thread.Sleep(1000 * 1);
                if (ticks == 0)
                {
                    break;
                }
                else
                {
                    ticks--;
                }
                Console.WriteLine("test:" + ticks);
            }
            Console.WriteLine("game over");
            Console.ReadLine();
        }
    }
拿控制台写的了！

DateTime endTime;
DateTime start;private void Form1_Load(object sender, EventArgs e) 
{ 
endTime= DateTime.Now.AddSeconds(30); 
timer1.Enabled = true; 
} 
private void timer1_Tick(object sender, EventArgs e) 
{ 
DateTime show = start.Subtract(new TimeSpan(DateTime.Now.Ticks)); 
label1.Text = show.ToLongTimeString(); 
}

Answer 3

  public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
                   }
        int x;
        private void Form1_Load(object sender, EventArgs e)
        {
            
            this.timer1.Interval = 1000;
                    }         private void button1_Click(object sender, EventArgs e)
        {
            timer1.Start();
            x = int.Parse(textBox1.Text.Trim());
        }        private void timer1_Tick(object sender, EventArgs e)
        {
            try
            {
                x--;
                label1.Text = x.ToString();
                if (x < 1)
                {
                    this.timer1.Stop();
                }            }
            catch (Exception ex)
            {
                MessageBox.Show("输入整数");
            }
        }    }
