C# equivalent of Notifiers?

[Shaun Hayward]

I was struggling to explain Notifiers to a C# developer the other day and it got me thinking... Do any of you know if there is a C# construct / class / whatever that offers the equivalent functionality of a LabVIEW Notifier?

CancellationTokenSource and CancellationToken provide the same signaling functionality. I don't know of anything that has the data transfer built in, but you might look around in the same assembly.

Thanks!

Wouldn't the  System.Threading.AutoResetEvent and  System.Threading.ManualResetEvent objects be similar, although in my opinion better known? And again they do not support an inherent data transfer but that could be of course added easily with subclassing.

Except the two you mention are both sealed classes.

Which would indeed require to wrap them instead of extending them. Wonder why they would be sealed. Seems to be the same as a Java class declared as final.

I've been told that any thread safe class has to be sealed as anyone who inherits pretty much cannot be type safe because they cannot be given safe access to all the mutexes/locks.
