Does Gc Call Discard?
The GC will not call dispose.

Why should gc SuppressFinalize be called when implementing the Dispose method?
The Dispose method is called, it releases the object’s resources. Discard must call GC. SuppressFinalize so that the garbage collector doesn’t call the object’s finalizer. To prevent derived types with finalizers from having to reimplement IDisposable and call it, unsealed types without finalizers must still call GC.
How does gc decide when to dispose of the object?
How does GC work? GC works on a managed heap, which is nothing more than a block of memory to store objects, when the garbage collection process starts, it looks for inactive objects and the objects that are no longer used, then compacts the space of the living object and try to free more memory.
What is garbage collection? What happens if you say system gc()?
The gc() method runs the garbage collector. Calling this suggests that the Java Virtual Machine strives to recycle unused objects so that the memory they currently occupy is available for fast reuse.
When should you call Dispose?
Rule of thumb: If a class implements IDisposable, you should always call the Dispose method as soon as you’re done using this resource. Even better wrap it in a using statement to ensure that the Dispose method will be called even if an exception is thrown: using (var reader = conn.
When should I implement IDisposable?
in a class, you must implement IDisposable and override the Dispose method to allow you to control when memory is freed. Otherwise, this responsibility is left to the garbage collector to release memory when the object containing the unmanaged resources is finalized.
Why is GC collection not recommended?
Calling GC. Collection is rarely necessary and can significantly affect application performance. This is because it triggers a lock operation that examines all objects in memory to clean them up. Also, you have no control over when this lock cleanup will actually run.
Why is the gc system not recommended?
Also, System. gc() can induce a full GC and the method will also wait until the full GC is ready. So it will not only destroy the performance of the code that calls GC, but it will probably destroy the performance of the entire JVM as well. In case it’s a server JVM, the results can be scary.
Is the gc system bad?
gc() can do nothing, and any code that “needs” the garbage collector to run is broken. However, for the pragmatic reason that it is bad practice to call System. gc() is that it is inefficient. And at worst, it’s horribly inefficient!
