Can we use events with threading C#?

Can we use events with threading C#?

Unless you do the marshaling yourself, an event will execute on whatever thread is invoking it; there’s nothing special about the way events are invoked, and your producer thread doesn’t have an event handler, your producer thread simply said “hey, when you fire this event, call this function”.

What synchronization primitive does the C# lock keyword make use of?

Use the lock statement in C# and the SyncLock statement in Visual Basic to synchronize access to a shared resource instead of using the Monitor class directly. Those statements are implemented by using the Enter and Exit methods and a try… finally block to ensure that the acquired lock is always released.

What is thread synchronization in C#?

Synchronization in C# is a mechanism that makes sure only one process or thread accesses the critical section of the program. All the other threads have to wait until the critical section is free before they can enter it. It makes sure that only one process or thread can use a resource at a time.

Do events run on separate threads?

What is Mutex and semaphore in C#?

A Mutex is a synchronization primitive that can work across processes — i.e., it can be used for inter process synchronization. A Semaphore on the contrary is one that allows you to limit the number of threads that have access to a shared resource at the same point of time.
