Value Type and reference type

Value Type (such as char, Int, and float), enumeration type, and structure type.

The reference types include the class type, interface type, delegate type, and array type.

The difference between a value type and a reference type is that a variable of the value type directly contains its data, while a variable of the reference type stores object references.

For the reference type, two variables may reference the same object. Therefore, operations on one variable may affect the objects referenced by another variable.

For value types, each variable has its own data copy, and operations on one variable cannot affect another variable.
