A deadlock occurs when two or more threads are waiting and blocking each other to release locks. The while loop keeps trying until both threads can acquire the locks, which breaks the loop and the threads complete their executions. Deadlock is a situation which occurs in a multi-process system where there is a resource sharing environment and when one process keep on holding the resource. If a thread cannot acquire the lock within one second, it releases the lock and tries again. In this program, we use the Monitor.TryEnter() to attempt to acquire a lock with a timeout of one second. Create two new threads that compete for the locks var thread1 = new Thread(AcquireLocks1) This happens when every process is waiting on an action from another process. The following program demonstrates how a deadlock scenario occurs when two threads complete multiple locks: using static System.Console There is a problem with the following code called deadlock. Both threads attempt to acquire the resources at the same time. Thread t1 needs to access r2 to proceed while thread t2 needs to access r1. Each thread holds a lock on a different shared resource r1 and r2. Particularly, each thread is holding onto a lock that the other thread needs, and neither can proceed until it can acquire the lock it’s waiting for.įor example, suppose you have two threads t1 and t2. Introduction to the C# deadlockĪ deadlock happens when two or more threads are blocking and waiting for each other to release the locks that they need to proceed. Summary: in this tutorial, you’ll learn about the C# deadlock, how it occurs, and how to fix it.
