Different objects implement the method different ways, changing the internal state of the object. Not all objects throw ObjectDisposedExceptions for all properties after the Dispose method is called, so there's really no sure fire way to determine whether or not it's been called. とりあえず私は、SemaphoreSlimを使っています。 普通のSemaphoreでもいいんですが、Slimのほうにはシグナルを待つためにWaitAsyncという Taskを返すメソッド があって、非同期処理と相性が良いようにも思えます。 type SemaphoreSlim = new : initialCount:int -> SemaphoreSlim + 1 overload member AvailableWaitHandle : WaitHandle member CurrentCount : int member Dispose : unit -> unit member Release : unit -> int + 1 overload member Wait : unit -> unit + 5 overloads Full name: System.Threading.SemaphoreSlim-----SemaphoreSlim(initialCount: int) : unit Semaphore & SemaphoreSlim. Semaphore class in .NET is a thin wrapper around the OS level counting semaphores synchronization object, which can be used to control access to a pool of resources, i.e.

The Dispose method leaves the SemaphoreSlim in an unusable state. After calling Dispose, you must release all references to the SemaphoreSlim so the garbage collector can reclaim the memory that the SemaphoreSlim was occupying.

Do I need to Dispose a SemaphoreSlim, Yes. It may use a ManualResetEvent that uses a SafeWaitHandle which is a SafeHandle and it has an unmanaged handle. You can see it in SafeHandle is finalizable so if you don't dispose of it (by disposing of the SemaphoreSlim) it will go to the finalizer that will need to do that for you. SemaphoreSlim doesn’t implement IAsyncDisposable, so all this does is use up another thread pool thread to run the Dispose..
