How do you lock a thread in C#?

The lock statement acquires the mutual-exclusion lock for a given object, executes a statement block, and then releases the lock. While a lock is held, the thread that holds the lock can again acquire and release the lock. Any other thread is blocked from acquiring the lock and waits until the lock is released.

Is lock thread safe C#?

No, it’s not thread safe.

Why should you avoid the lock keyword?

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.

What are locks in threading?

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.

What is multi threading in C#?

Multithreading in C# is a process in which multiple threads work simultaneously. It is a process to achieve multitasking. It saves time because multiple tasks are being executed at a time. To create multithreaded application in C#, we need to use System. Threding namespace.

What is the difference between lock and Monitor in C#?

Answer: Lock Vs Monitor in C# multithreading: Difference between monitor and lock in C# is that lock internally wraps the Enter and Exit methods in a try… finally block with exception handling. Whereas for Monitor class in C#, we use try and finally block explicitly to release lock properly.

Can two threads acquire the same lock?

Locks only provide mutual exclusion with other threads that acquire the same lock. All accesses to a data variable must be guarded by the same lock. You might guard an entire collection of variables behind a single lock, but all modules must agree on which lock they will all acquire and release.

Can a thread acquire multiple locks?

A thread can safely acquire the same lock multiple times without running into deadlocks (e.g. a synchronized method calls another synchronized method on the same object).

Is mutex and lock the same?

A lock allows only one thread to enter the part that’s locked and the lock is not shared with any other processes. A mutex is the same as a lock but it can be system wide (shared by multiple processes).

Can a thread acquire more than one lock mutex?

Can a thread acquire more than one lock (Mutex)? Yes, it is possible that a thread is in need of more than one resource, hence the locks. If any lock is not available the thread will wait (block) on the lock.
