Sep 26, 2017 Currently available thread synchronization techniques in c-sharp are Lock/ Monitor, Mutex, Semaphore and SemaphoreSlim. Lock vs Monitor.

Call Dispose when you are finished using the SemaphoreSlim.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.. For more information, see Cleaning Up Unmanaged Resources and Implementing a Dispose … If you access the AvailableWaitHandle property, then Yes, you must call Dispose() to cleanup unmanaged resources. If you do not access AvailableWaitHandle, then No, calling Dispose() won't do anything important. SemaphoreSlim will create a ManualResetEvent on demand if you access the AvailableWaitHandle. System.Threading.SemaphoreSlim.Dispose() Here are the examples of the csharp api class System.Threading.SemaphoreSlim.Dispose() taken from open source projects. By voting up you can indicate which examples are most useful and appropriate.

After calling Dispose, you must release all references to the SemaphoreSlim so the garbage collector can reclaim the memory that the SemaphoreSlim was occupying. For more information, see Cleaning Up Unmanaged Resources and Implementing a Dispose Method. The documentation of SemaphoreSlim says 'Dispose should only be used when all other operations have completed'. How should the following class be adjusted so thread B can call Dispose() while thread A is awaiting Async().

This stems from the problem where I wanted to dispose of my class containing the SemaphoreSlim instance, and was unsure how to safely and elegantly deal with the SemaphoreSlim instance as well. I'm still not sure if this is the right approach:

I'm still not sure if this is the right approach: 2015-08-17 I did swap _isDisposed=true and _semaphore.Release() around in its Dispose though in case it somehow got called multiple times. Also it is important to note SemaphoreSlim is not a reentrant lock, meaning if the same thread calls WaitAsync multiple times the count the semaphore has is decremented every time.

SemaphoreSlim object is used to control the access to a resource like calling other API or limiting the I/O operations concurrently to avoid unnecessary network/hardware issues.

It may use a ManualResetEvent that uses a SafeWaitHandle which is a SafeHandle and it has an unmanaged handle.

I often use the SemaphoreSlim, and I love that it supports async await. However, I don't like always having to create a try finally block around every use call to ensure that the release method gets called.

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.

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.

A while ago I wanted to upload al my home photo/video archive to Google Drive. I love bicycles as many developers do so why not to write my own uploader on C# :) Boom! In the place, I’m currently living (Krakow, Poland) the internet connection is very bad, upload is ~7 Mbps.

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. 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.
