ReadWrite Lock
Learn to design and implement a ReadWrite Lock in C# that enables multiple readers to access data simultaneously while ensuring only one writer has exclusive access. Understand the use of monitors, reader counts, and writer flags to coordinate access and prevent deadlocks in concurrent programming scenarios.
We'll cover the following...
ReadWrite Lock

Solution
First of all let us define the APIs our class will expose. We'll need two for writer and two for reader. These are:

This problem becomes simple if you think about each case:
Before we allow a reader to enter the critical section, we need to make sure that there's no writer in progress. It is ok to have other readers in the ...
