ReaderWriterLockSlim rwLock = new ReaderWriterLockSlim(); // acquire the upgradeable read lock rwLock.EnterUpgradeableReadLock(); // perform some read operations // upgrade the read lock to write lock rwLock.EnterWriteLock(); // perform some write operations // exit the write lock rwLock.ExitWriteLock(); // exit the upgradeable read lock rwLock.ExitUpgradeableReadLock();
ReaderWriterLockSlim rwLock = new ReaderWriterLockSlim(); ListIn this example, we use the read lock to access the numbers list and then use the write lock to add some more numbers to it. Overall, the ReaderWriterLockSlim class and its methods are used to safely synchronize access to shared resources in multi-threaded applications.numbers = new List (); // add some numbers to the list numbers.Add(1); numbers.Add(2); // acquire the read lock rwLock.EnterReadLock(); // use the numbers list // exit the lock rwLock.ExitReadLock(); // acquire the write lock rwLock.EnterWriteLock(); // add some more numbers to the list numbers.Add(3); numbers.Add(4); // exit the lock rwLock.ExitWriteLock();
