Value Type

Reference Type

A Value Type holds the data within its own memory allocation...

A Reference Type contains a pointer to another memory location that holds the real data...

Value Type variables (Predefined datatypes (char, float, int, long, short,...), Structures, Enums...)

Reference Type variables (Classes, Objects, Arrays, Indexers, Interfaces...)

Value Type variables are stored in the stack

Reference Type variables are stored in the heap

Value types can be created at compile time and stored in stack memory, because of this, Garbage collector can't access the stack

Reference Type variables are stored in heap memory. This means that when a reference type variable is no longer used, it can be marked for garbage collection

int x = 20;

int[] iArray = new int[10];
