Can be used: Monitor.TryEnter () method, the code from the Internet.
While this approach can solve the deadlock problem, but it is best not to deadlock the case. If a deadlock this happens, it shows the code in question ah. Or else in which to add a log to record it, and then resolve.
class Program { static void Main(string[] args) { object lock1 = new object(); object lock2 = new object(); new Thread(() => LockTooMuch(lock1, lock2)).Start(); lock (lock2) { Thread.Sleep(1000); Console.WriteLine("Monitor.TryEnter allows not to get stuck,returning false after a specified timeout is elapsed"); if (Monitor.TryEnter(lock1, TimeSpan.FromSeconds(5))) { Console.WriteLine("Acquired a protected resource succesfully"); } else { Console.WriteLine("Timeout acquiring a resource!"); } } //new Thread(() => LockTooMuch(lock1, lock2)).Start(); //Console.WriteLine("----------------------------------"); //lock (lock2) //{ // Console.WriteLine("This will be a deadlock!"); // Thread.Sleep(1000); // lock (lock1) // { // Console.WriteLine("Acquired a protected resource succesfully"); // } //} Console.ReadKey(); } static void LockTooMuch(object lock1, object lock2) { lock (lock1) { Thread.Sleep(1000); lock (lock2) ; } } }
