C# - 如果等待时间很长，请帮助跳过 [重复]

Question

我对任务和异步非常陌生，我对如何取消等待 var 状态感到困惑，如果 ping 成功则需要太长时间，但如果它没有 ping 大约 10 秒，这是不切实际的当我想尽快对列表进行排序时

public async void GetServersV2(List<string> ls)
        {
            for (int i = 0; i < ls.Count; i++)
            {
                IMinecraftPinger pinger = new MinecraftPinger(ls[i], (short)port);
                
                try
                {
                    var statuss = await pinger.PingAsync();
                    Console.WriteLineFormatted($"Server: " + ls[i] + " is {0} | {3} online is " + statuss.Players.Online + "/" + statuss.Players.Max + " | " + "{4} is: " + statuss.Version.Name, Color.White, status);
                }
                catch
                {
                    Console.WriteLineFormatted("Server: " + ls[i] + " is {1}", Color.White, status);
                }
            }

        }

一个选项是，运行 2 个任务，pingerTask 和一个 delayTask，并等待第一个获胜：

var pingTask = pinger.PingAsync(); // start the task, but do not await it
var timeoutTask = Task.Delay(TimeSpan.FromSeconds(10)); // create some timeout task
var winnerTask = await Task.WhenAny(pingTask, timeoutTask); // now await until either the timeoutTask or pingTask finishes

if (winnerTask == pingTask) // if the ping is done before the timeout, then...
{
    var statuss = await pingTask;
}
else
{
     // you run into a timeout
}
