Serialization of this class behaves in the same way as built-in locks: a deserialized lock is in the unlocked state, regardless of its state when serialized. Sample usages. Here is a code sketch showing how to perform lock downgrading after updating a cache (exception handling is particularly ...
Tries to enter the lock in read mode, with an optional integer time-out. C++ public: IDisposable ^ TryEnterReadLock(TimeSpan timeout); Parameters timeout TimeSpan The interval to wait, or -1 milliseconds to wait indefinitely. Returns ...
However, if a writer and a reader or two writers access the resource simultaneously, the result becomes indeterminable (which is the case you see above). Therefore the writers must have exclusive access to the resource. Press any key to close the program’s window and return to ...

Because interlocked operations were built for cross-thread communication, they have strong ordering guarantees. No read or write can move in either direction past an interlocked operation. Unfortunately, interlocked operations are relatively expensive, on the order of several dozen to up to hundreds of...
