Explain memory management in C#. How does garbage collection (GC) work?

Question

ICSM Computer · Answer

Answer:
C# uses automatic memory management via the .NET Garbage Collector (GC).
GC allocates objects on the managed heap.When objects become unreachable, the GC reclaims memory.Generational GC (Gen 0, Gen 1, Gen 2) improves performance by:
Collecting short-lived objects more frequently.Promoting surviving objects to older generations.
Best practices:
Avoid large object allocations frequently.Use IDisposable and using for unmanaged resources.Avoid memory leaks by breaking references (especially in events).
