What is garbage collection in C#?

The garbage collector (GC) manages the allocation and release of memory. The garbage collector serves as an automatic memory manager.

• You do not need to know how to allocate and release memory or manage the lifetime of the objects that use that memory.

• An allocation is made any time you declare an object with a “new” keyword or a value type is boxed. Allocations are typically very fast.

• When there isn’t enough memory to allocate an object, the GC must collect and dispose of garbage memory to make memory available for new allocations.

• This process is known as garbage collection.

Garbage Collection in C# has the following advantages −

• You don’t need to free memory manually while developing your application.

• It also allocates objects on the managed heap efficiently.

• When objects are no longer used then it will reclaim those objects by clearing their memory, and keeps the memory available for future allocations.

• Managed objects automatically get clean content to start with, so their constructors do not have to initialize every data field.
