Mixing
WaitOne with C# doesn't auto reset
0
Obviously the mistake has to be on my end:
var Event = new AutoResetEvent(false);
var T = new Timer(_ =>
{
Console.Write("T");
Event.Set();
}, null, 0, 10 * 1000);
while (true)
{
Console.Write("W");
Event.WaitOne();
}
The output of this code is:
WTWWWWWWWWWWWWWWWWWW[..]TWWWWWWWWWWWW...
The expected output is:
WTWTWTWTWTWTWTWT
So, for some reason, once signaled the auto reset event doesn't seem to auto reset. What did I miss?

That's strange, I ran your code and it prints your expected result.

Are you sure your wrong output wasn't generated by theManualResetEvent? Is so, that would be perfectly reasonable to get theWTWWWWWWWWW[...]TWWWWsince it will only block once and everything else will happen irrespective of the lock unless you reset the event but forAutoResetEvent[Slim]you should get the desired output.

Please give us more background: which OS? which .NET Framework version? (or maybe Mono/Core?)

This is .net core 2.1 on Mac. The event does behave like a manual reset event, but it shouldn't. I event tried to manually reset the event just to see, but no change. At the same time, I have a hard time to believe this could be a bug because I imaging that these synchronization objects are probably used a lot and will have unit tests.
