What is the difference between ManualResetEvent and AutoResetEvent in .NET?

I have read the documentation on this and I think I understand. An AutoResetEvent resets when the code passes through event.WaitOne(), but a ManualResetEvent does not.

Is this correct?

Yes. It's like the difference between a tollbooth收费亭；收费站 and a door.

The ManualResetEvent is the door, which needs to be closed (reset) manually.

The AutoResetEvent is a tollbooth, allowing one car to go by and automatically closing before the next one can get through.

Or like a door and a turnstile. 旋转栅门(常设于公共建筑、体育场等入口处); 也类似于地铁站刷卡过的那个栏杆
