This article applies not only to C#, but also to other languages with references, like C++.
A reference is a special type
that allows you to access data stored in another location separate from
the variable that contains the reference. When accessing a reference
variable, indirection is automatically performed, i.e. first the actual
address to the remote variable is fetched, then the object stored in the
variable is accessed. This behaviour is distinct from pointers, which
employ the same indirection mechanisms, but are treated as normal values
and so dereferencing must be explicit.
