我想在 C# 中定期檢查 60 秒。我可以通過(guò)定期檢查日期來(lái)做到這一點(diǎn)，如下所示但是，當(dāng)我使用秒表時(shí)，秒表會(huì)重置回開(kāi)始位置，而不是從上次停止時(shí)繼續(xù)。using System;using System.Diagnostics;using System.Threading;namespace StopwatchExample{ class Program { static void Main() { ////Works //DateTime start = DateTime.Now; //while (true) //{ // DateTime current = DateTime.Now; // var diffInSeconds = (current - start).TotalSeconds; // if (diffInSeconds > 5) // { // Console.WriteLine("5 s done!"); // break; // } //} // Does not work Stopwatch stopwatch = new Stopwatch(); stopwatch.Start(); while (true) { stopwatch.Stop(); if (stopwatch.Elapsed.Seconds > 5) { Console.WriteLine("5 s done!"); break; } else { stopwatch.Start(); } } Console.ReadLine(); } }}

嘗試使用 Timer (System.Timers) 而不是 Stopwatch。設(shè)置所需的時(shí)間間隔并對(duì) Elapsed 事件執(zhí)行必要的操作。
在這里您可以了解更多信息。
例子：
public static void Main()
{
// Create a timer and set a two second interval.
aTimer = new System.Timers.Timer();
aTimer.Interval = 2000; // 2000ms == 2s
// Hook up the Elapsed event for the timer.
aTimer.Elapsed += OnTimedEvent;
// Have the timer fire repeated events (true is the default)
aTimer.AutoReset = true;
// Start the timer
aTimer.Enabled = true;
Console.WriteLine("Press the Enter key to exit the program.");
Console.ReadLine();
}
private static void OnTimedEvent(Object source, System.Timers.ElapsedEventArgs e)
{
Console.WriteLine("The interval has been elapsed");
}

正如其他人所說(shuō)， aTimer可能是更好的解決方案。鑒于您對(duì) 的使用Stopwatch，您需要將邏輯更改為：
Stopwatch stopwatch = new Stopwatch();
stopwatch.Start();
while (true)
{
// Check elapsed time w/o stopping/resetting the stopwatch
// May want to include the 5 seconds themselves (>= instead of >)
if (stopwatch.Elapsed.Seconds >= 5)
{
// At least 5 seconds elapsed, restart stopwatch.
stopwatch.Stop();
stopwatch.Start();
Console.WriteLine("5 s done!");
// Not sure about this, if you really want to check "periodically",
// this break makes less sense, because the checking
// logic will stop after the first 5 seconds have elapsed.
break;
}
}
