WebAug 5, 2024 · \$\begingroup\$ I didn't downvote but you know ConcurrentDictionary is already thread safe and you can just use GetOrAdd that takes a func. Having the lock seems overkill.

WebThe FileCache is not thread safe, so you need to make it so. Solution The FileCache class uses a local disk to read and write output files. You need to implement thread safe reading and writing to disk. To do this, use the list to store the key or the file ID and associated object you need to lock. WebJul 22, 2024 · After much prompting from this post I wanted to build a simple, in-memory, thread-safe cache.

The second is to continually remove from the collection until it's empty, e.g. T ignored; while (cq.TryDequeue (out ignored));.
WebApr 26, 2015 · A MemoryCache is thread-safe but there is no reason to assume it's a singleton. If you want different threads to access the same MemoryCache instance you need to give them all a reference to the same instance (either as a singleton (really bad) static (still bad) or through argument passing as dependency injection (good)). WebIn C#, the MemoryCache class provides a way to store data in memory and retrieve it quickly. However, when multiple threads access the cache concurrently, it's important to ensure that the cache is accessed in a thread-safe way. One way to achieve this is by using the GetOrCreateAsync method of the MemoryCache class.
