In .NET, what is the specific type of object reference?

those. what is the name of a data structure like the value stored on the stack that references the object on the heap?

those. is the object reference a System.What (if anything)?

I know this is not a pointer , or is it?

I know this is an "how to" pointer.

I know this is "owned by the garbage collector."

I superstitiously believe that when creating an instance of an object (i.e. a reference type) that IL gives a command in the CLR to allocate a "control stack / pair of heap values" in memory (e.g.

...
      .locals init ([0] int32 i1,
               [1] object o1,
               [2] int64 l1)
      IL_0000:  nop
      IL_0001:  ldc.i4.4
      IL_0002:  stloc.0
      IL_0003:  newobj     instance void [mscorlib]System.Object::.ctor()
      IL_0008:  stloc.1
      IL_0009:  ldloc.0
      IL_000a:  box        [mscorlib]System.Int32
...
