How is the structure and storage of reference types organized in memory in C#?

In C#, reference types (such as classes) are stored in the managed heap. A reference variable, declared on the stack or in another object, contains a pointer to the memory area in the heap where the object itself is located.

When a class object is created, the CLR allocates memory on the heap to store the object's fields. The reference variable is stored on the stack (if it is a local variable) and contains the address of this object.

Thus, the storage structure is:

• Reference (pointer) — on the stack or in another object
• Object — on the heap

This allows multiple references to point to the same object and provides dynamic memory management through the garbage collector.
