Types of memory management in C#
In C#, memory is allocated for objects in two places: the stack and the heap.
1. Stack memory: The stack is a region of memory that is used to store data that is local to a function or a block of code. When a method or function is called, memory is allocated on the stack to store local variables and parameters. The stack is a fixed-size data structure that operates on a last-in, first-out (LIFO) basis, meaning that the last item that was added to the stack is the first one to be removed. The stack memory is automatically managed by the .NET runtime, and memory is automatically released when the function or block of code completes.
2. Heap memory: The heap is a region of memory that is used to store data that is not local to a function or a block of code. When an object is created in C#, memory is allocated on the heap to store the object's data and any associated references. The heap is a dynamic data structure that is not fixed in size, and memory is allocated and deallocated as needed. The heap memory is managed by the .NET runtime through a garbage collector, which periodically checks for objects that are no longer being used by the application and frees the memory associated with those objects.
In general, variables that are primitive types or value types are allocated on the stack, while variables that are reference types (such as objects) are allocated on the heap. However, it's important to note that the exact allocation of memory is determined by the .NET runtime and can vary based on the specifics of the application and the environment.
