Difference Between Value vs Reference Type Variables

Difference Between Value vs Reference Type Variables

Difference between Value vs Reference Type variables


Good day! Hope you have to have long gone by our most interesting
.net main job interview issues,
c# content. Now, we will see the big difference among worth sort and reference sort
variables. All the data Styles in .Web
are possibly managed by Value Variety or Reference Sort variables.

A Worth Type variable possesses the knowledge in its memory place and a
Reference Form variable carries a pointer to a further memory spot that carries
the serious facts. The Benefit Type variables get stored in the stack whilst
Reference Type variables get stored in the heap.

Worth Type variable:

A Value Style variable merchants its contents in the memory which is allotted on
the stack. Often, when we develop a Price Sort variable, a distinctive area in
memory is allotted to get the price saved and that variable carries a benefit
definitely. If you assign this variable to a further variable, the benefit will be
copied straight and both of those variables commence working independently. Beforehand
declared knowledge kinds, buildings, and enums are also thought of value types and
perform in the exact same solution. Also, Benefit sort variables can be generated at
the time of compilation and can be saved in stack memory. The garbage
collector is not able to entry this stack due to the fact of this variable.

int x=21


Right here the benefit 21 is saved in the stack memory place.

Reference Form variable

Reference Form variables are used by a reference that possesses a
reference or deal with to one more object but not the similar object itself. Because
reference-variety variables depict the area particulars of that variable rather
than the exact same data alone, assigning a precise reference variable to a further
just one, doesn’t copy the data. Rather, it generates a 2nd duplicate of the
reference variable, which relates to the exact same distinct site of the
specific heap as the real worth. Reference Style variables get saved in
different locations of memory named heap. It means when a reference kind variable is
no lengthier utilized, it can be captioned for rubbish assortment.

Examples of reference-kind variables are
Courses, Arrays,
Objects, Interfaces, Indexers, etcetera.


int iArray[] =new int[31]

In the above case in point with code, the room preferred 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 used for
static memory allotment, but both of those are stored in the RAM of computer.

Let us explore some a lot more price form and reference style variables.  

Course and Struct

is deemed as a variable of pass-by-reference and Struct is regarded as a
variable of pass-by-copy, it implies that Class is a reference class
variable and its item is developed on the heap memory whilst the framework is a
benefit classification variable and its object is developed on the stack memory.

Dynamic Data Sort

dynamic data kind
idea brings some new attributes to C# 4. Nonetheless, Dynamic Form depicts that
you will be in a position to keep any sort of worth or knowledge in the dynamic variable
mainly because verifying of details sort for dynamic groups of variables occurs at


I hope the higher than write-up on the differentiation of worth kind and reference
type could help freshers or beginners in the development industry. These
variables are a significant component of database conversation for finish-end users.
