EventWaitHandle WaitOne错误与TimeSpan大约1年

Question

I'm fetching TimeSpan for 1 year and trying to do WaitOne for EventWaitHandle , but getting error,

How to handle this case?

System.ArgumentOutOfRangeException: 'Number must be either non-negative and less than or equal to Int32.MaxValue or -1. Parameter name: timeout'

private static readonly EventWaitHandle eventWait = new AutoResetEvent(false);
    static void Main(string[] args)
    {

        try
        {
            var span = TimeSpan.FromMilliseconds(Math.Round((DateTime.Now.AddYears(1) - DateTime.Now).TotalMilliseconds, 3));

            if (eventWait.WaitOne(span))
            {
                Console.WriteLine("test");
            }

        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.StackTrace.ToString());
        }
    }

Answer 1

Math.Round((DateTime.Now.AddYears(1) - DateTime.Now).TotalMilliseconds, 3) <= int.MaxValue

is

false

Regard doc your timespan is to big since int.MaxValue in maximum timespan value that EventWaitHandle.WaitOne(TimeSpan) consumes w/o exception.

You can try -1 for infinite wait.
