Difference between Value vs Reference Type variables


Hello there! Hope you should have absent by our most appealing
.net main job interview thoughts,
c# posts. Now, we will see the variation concerning price form and reference type
variables. All the knowledge Styles in .Net
are possibly managed by Price Type or Reference Variety variables.

A Benefit Kind variable possesses the knowledge within its memory area and a
Reference Style variable carries a pointer to a further memory space that carries
the true knowledge. The Value Style variables get saved in the stack although
Reference Variety variables get saved in the heap.

Benefit Kind variable:

A Price Type variable shops its contents in the memory which is allotted on
the stack. Frequently, when we create a Benefit Style variable, a exceptional area in
memory is allotted to get the worth saved and that variable carries a benefit
surely. If you assign this variable to a further variable, the value will be
copied directly and the two variables commence operating independently. Formerly
declared data varieties, buildings, and enums are also considered price forms and
carry out in the very same method. Also, Price sort variables can be produced at
the time of compilation and can be stored in stack memory. The rubbish
collector is unable to accessibility this stack simply because of this variable.

int x=21


Right here the value 21 is stored in the stack memory place.

Reference Sort variable

Reference Type variables are used by a reference that possesses a
reference or handle to a different object but not the very same object alone. Since
reference-type variables depict the site facts of that variable rather
than the identical data alone, assigning a certain reference variable to a further
a person, doesn’t copy the details. Rather, it generates a 2nd copy of the
reference variable, which relates to the exact same individual site of the
unique heap as the real worth. Reference Form variables get stored in
many areas of memory named heap. It implies when a reference form variable is
no for a longer time utilized, it can be captioned for rubbish assortment.

Examples of reference-variety variables are
Classes, Arrays,
Objects, Interfaces, Indexers, and so forth.


int iArray[] =new int[31]

In the over example with code, the area wanted for the 31 integers that
compose up the array is allotted on the heap.

Heap and Stack

Heap is used for dynamic memory allotment, and Stack is utilized for
static memory allotment, but both of those are saved in the RAM of computer system.

Let us talk about some extra benefit type and reference variety variables.  

Class and Struct

is deemed as a variable of move-by-reference and Struct is viewed as as a
variable of pass-by-duplicate, it signifies that Course is a reference group
variable and its item is crafted on the heap memory whilst the framework is a
value group variable and its object is created on the stack memory.

Dynamic Facts Form

dynamic info style
notion delivers some new capabilities to C# 4. Nonetheless, Dynamic Sort depicts that
you will be capable to retail outlet any kind of worth or info in the dynamic variable
due to the fact verifying of knowledge variety for dynamic groups of variables takes place at


I hope the earlier mentioned posting on the differentiation of value sort and reference
type could assistance freshers or rookies in the progress subject. These
variables are a sizeable aspect of database conversation for close-buyers.
