SemaphoreSlim doesn’t implement IAsyncDisposable, so all this does is use up another thread pool thread to run the Dispose.. Derived Classes. If you are writing a base class that might have derived classes with resources that need disposing asynchronously, you may wish to introduce a virtual DisposeAsync method if you also have a base Dispose method.

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

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.

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.

SemaphoreSlim类有几个私有字段很重要,m_currentCount表示可用资源,如果m_currentCount>0每次调用Wait都会减1,当m_currentCount<=0时再次调用Wait方法就会阻塞。每次调用Release方法m_currentCount都会加1.m_maxCount表示最大可用资源数,是在构造函数中指定的。
