The difference between a destructor and a finalizer?
2010年2月17日 · A 'finalizer' is a term used in the Common Language Runtime, for example in calls to GC.WaitForPendingFinalizers(), and it refers to any .net language, not just C#. Any .net reference type can have a finalizer. For a C# class (the source code artifact), the destructor compiles into the CIL method which is the CLR type's finalizer.
c# - Finalize vs Dispose - Stack Overflow
2009年4月9日 · The finalizer is for implicit cleanup - you should use this whenever a class manages resources that absolutely must be cleaned up as otherwise you would leak handles / memory etc... Correctly implementing a finalizer is notoriously difficult and should be avoided wherever possible - the SafeHandle class (avaialble in .Net v2.0 and above) now ...
In C# what is the difference between a destructor and a Finalize …
2017年4月10日 · Wikipedia has some good discussion on the difference between a finalizer and a destructor in the finalizer article. C# really doesn't have a "true" destructor. The syntax resembles a C++ destructor, but it really is a finalizer. You wrote it correctly in the first part of your example: ~ClassName() { } The above is syntactic sugar for a ...
c# - Finalizers and Dispose - Stack Overflow
2014年4月14日 · The finalizer should set the flag using something like a CompareExchange, and the thread should use a similar means to test it. Note that if the finalizer of one object accesses another object, the other object may have been finalized but it will still exist.

How do I write proper destructors and finalizers?
2013年11月3日 · The finalizer should clean up unmanaged resources (so everything gets cleaned up when the object is garbage-collected. The destructor should clean up managed resources (delete Foo or Foo.Dispose()?) and call the finalizer (according to 1) Both the destructor and the finalizer can be called multiple times (see 3 p. 26 end of 8.8.8)
Garbage Collection and Finalizers: Finer Points - Stack Overflow
Objects that contain a finalizer tend to live longer. When, during a collect, the GC marks an object with a finalizer as being garbage, it will not collect that object (yet). The GC will add that object to the finalizer queue that will run after the GC has finished. Consequence of this is that, because this object is not collected, it moves to ...
What are the Finalizer Queue and Control+ThreadMethodEntry?
2021年2月5日 · The finalizer queue holds all objects that have a finalizer method defined. Recall that a finalizer is a means to collect unmanaged resources like handles. When the garbage collector collects garbage, it moves any objects with a finalizer into the finalizer queue.
c# - How do I unit test a finalizer? - Stack Overflow
2016年1月20日 · This is really quite clever. It does indeed force the finalizer to run, and gets me 90% to where I wanted to be. However in my case, I need to be able to use a Fakes Shim as well, and the code running in the AppDomain doesn't see the Shim. I can't create the shim inside the DoCallback either because it will be out of scope before the finalizer ...
c# - Static Finalizer - Stack Overflow
2008年11月1日 · The true value of a static finalizer--from the perspective of a Delphi developer where such things are supported at the language level--isn't some nonsensical "guarantee that this will run," (as you point out, someone could always pull the plug,) but rather a guarantee that it will run when the class goes out of scope.
