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 the 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.

Hello Deepak,

Garbage collection is a low-priority process that serves as an automatic memory manager which manages the allocation and release of memory for the applications. Each time a new object is created, the common language runtime allocates memory for that object from the managed Heap. As long as free memory space is available in the managed Heap,the runtime continues to allocate space for new objects. However, memory is not infinite, and once an application fills the Heap memory space, garbage collection comes into play to free some memory.

When the garbage collector performs a collection, it checks for objects in the managed Heap that are no longer being used by the application and performs the necessary operations to reclaim the memory. Garbage collection will stop all running threads, it will find all objects in the Heap that are not being accessed by the main program and delete them. It will then reorganize all the objects left in the Heap to make space and adjust all the Pointers to these objects in both the Stack and the Heap.

To enforce garbage collection in your code manually, you can run the following command (C#):
