Note that in other dynamic languages this could be different, but in C# this is always a value copy. When value type is created, a single space most likely in <a href='http://gribblelab.org/CBootcamp/7_Memory_Stack_vs_Heap.html#orgheadline2' target='_blank' rel='nofollow'>stack</a> is created, which is a "LIFO" (last in, first out) data structure. The stack has size limits and memory operations are efficient. Few examples of built-in data types are `int, float, double, decimal, char and string`.
