Runs a method when an event or semaphore is signaled. A timeout value can also be specified, causing the delegate to run after the time span has elapsed if the named event does not occur (or if the semaphore does not reach a signaled state).

Methods

AttachToEvent(String, SignalHandler) AttachToEvent(String, SignalHandler) AttachToEvent(String, SignalHandler) AttachToEvent(String, SignalHandler)

Attaches a SignalHandler delegate to an event. The delegated method will run the next time the event occurs.
AttachToEvent(String, SignalHandler, TimeSpan) AttachToEvent(String, SignalHandler, TimeSpan) AttachToEvent(String, SignalHandler, TimeSpan) AttachToEvent(String, SignalHandler, TimeSpan)

Attaches a SignalHandler delegate to an event. The delegated method will run if the event occurs or the time span elapses, whichever comes first.
AttachToSemaphore(String, SignalHandler) AttachToSemaphore(String, SignalHandler) AttachToSemaphore(String, SignalHandler) AttachToSemaphore(String, SignalHandler)

Attaches a SignalHandler delegate to a named semaphore. The delegated method will run when the named semaphore is signaled.
AttachToSemaphore(String, SignalHandler, TimeSpan) AttachToSemaphore(String, SignalHandler, TimeSpan) AttachToSemaphore(String, SignalHandler, TimeSpan) AttachToSemaphore(String, SignalHandler, TimeSpan)

Attaches a SignalHandler delegate to a named semaphore and specifies a timeout value. The delegated method will run when the named semaphore is signaled, or if the time span elapses before the semaphore reaches a signaled state.
