lock keyword in C# is used to place around a critical section of code, where we want to allow only one thread to access the resource at a time. Any other thread cannot access the lock and it waits for the lock to be released.

semaphore available in C#.
All of these classes (lock, monitor, mutex, and semaphore) provide a synchronization mechanism to protect the shared code or resources in a multithreaded application.
