CSharp中的倒计时

简单示例

代码语言：javascript复制

private void Countdown()
{
    // 设置倒计时时间（以毫秒为单位）
    int countdownTime = 5000;
    Stopwatch stopwatch = Stopwatch.StartNew();
    while (stopwatch.ElapsedMilliseconds < countdownTime)
    {
        // 剩余时间 = 倒计时时间 - 已经流逝的时间
        int remainingTime = countdownTime - (int)stopwatch.ElapsedMilliseconds;

        // 输出剩余时间
        Console.WriteLine(
            @"Remaining Time: {0} milliseconds",
            remainingTime
        );

        // 可以根据需要选择适当的时间间隔，这里选择1秒
        Thread.Sleep(1000);
    }
    Console.WriteLine(@"Countdown finished!");
}
