What is not so simple is finding that pointer back. The CLR is heavily invested in ensuring that can be done reliably and efficiently. Such pointers can be stored in many different places. The easier ones to find back are object references stored in a field of an object, a static variable or a GCHandle. The hard ones are pointers stored on the processor stack or a CPU register. Happens for method arguments and local variables for example.

The CLR also permits allocating handles to objects, extra references. Exposed as the GCHandle type in .NET, but only necessary if the GC needs help determining if an object should stay alive or should not be moved. Only relevant if you interop with unmanaged code.
