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();
}

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");
}
}
