Say I have three threads that need access to a collection and I use a lock block around the access in each thread. The following happens...
(1) Thread 1 gets the lock on the collection
(2) Thread 2 gets blocked
(3) Thread 3 gets blocked
When Thread 1 releases the lock, who gets to take the lock next? Is it FIFO access?
Thanks

C# Lock keyword ensures that one thread is executing a piece of code at one time. The lock keyword ensures that one thread does not enter a critical section of code while another thread is in that critical section. Lock is a keyword shortcut for acquiring a lock for the piece of code for only one thread.
Avoid using 'lock keyword' on string object String object: Avoid using lock statements on string objects, because the interned strings are essentially global in nature and may be blocked by other threads without your knowledge, which can cause a deadlock.
Exclusive locking in threading ensures that one thread does not enter a critical section while another thread is in the critical section of code. If another thread attempts to enter a locked code, it will wait (block) until the object is released.
Both Monitor and lock provides a mechanism that synchronizes access to objects. lock is the shortcut for Monitor. Enter with try and finally. Lock is a shortcut and it's the option for the basic usage.
You should not care who gets the lock next.
