Pastebin is a website where you can store text online for a set period of time. When you have multiple threads trying to do work at the same time, and you want to throttle how many of them are actually executing, you can use SemaphoreSlim. Grocery stores have a limited number of…
2011-03-13 · SemaphoreSlim.Wait checks whether m_lockObj is null, throwing an ObjectDisposedException if it is, and then uses Monitor.Enter(m_lockObj, ). If the semaphore were to be disposed between the check for m_lockObj == null and using Enter(m_lockObj, ), a null object could be passed to Monitor.Enter, which could result in an ArgumentNullException coming from Monitor.Enter. 35/// The

Do not dispose the SemaphoreSlim held by AsyncSemaphore.

这是官方文档 SemaphoreSlim.Dispose Method (System.Threading). 这句话 Always call Dispose before you release your last reference to the SemaphoreSlim 的本质意思就是在调用 Dispose 之前需要编程开发者确保已经释放完成了所有的任务。
A while ago I wanted to upload al my home photo/video archive to Google Drive. This "mutex" has visibility different from the state it's trying to protect. You may get away with it here if this is the only code that accesses that particular key in the cache, but work or not, it's a bad practice. With async/await becoming more and more prevalent in modern code so has the need for async synchronization constructs. Unlike their synchronous counterparts (e.g. Monitor, Mutex, ReaderWriterLock, etc.) .NET doesn’t offer almost any built-in asynchronous synchronization constructs, but it does contain the basic building blocks to build them on your own (mainly Task, TaskCompletionSource Release (); locker. Dispose ();}}); SemaphoreSlim semaphore = SemaphoreSlims. GetOrAdd (key, new SemaphoreSlim (1, 1)); semaphore.

Do I need to Dispose a SemaphoreSlim (3) For many other classes I would agree with i3arnon, but for SemaphoreSlim I'll go with Tim's comment. If you use SemaphoreSlim in a low-level class and have to dispose it then practically everything in your program will become IDisposable when in fact it is not necessary.
All public and protected members of SemaphoreSlim are thread-safe and may be used concurrently from multiple threads, with the exception of Dispose (), which must be used only when all other operations on the SemaphoreSlim have completed.
