Difference between Value vs Reference Type variables


Howdy! Hope you will have to have gone through our most exciting
.web core job interview thoughts,
c# content. Now, we will see the variation among price variety and reference sort
variables. All the knowledge Forms in .Net
are either taken care of by Worth Style or Reference Kind variables.

A Worth Style variable possesses the info inside its memory area and a
Reference Form variable carries a pointer to yet another memory spot that carries
the genuine data. The Worth Type variables get stored in the stack when
Reference Style variables get saved in the heap.

Worth Kind variable:

A Benefit Form variable shops its contents in the memory which is allotted on
the stack. Usually, when we make a Price Style variable, a distinctive space in
memory is allotted to get the value saved and that variable carries a benefit
undoubtedly. If you assign this variable to another variable, the price will be
copied immediately and both variables begin performing independently. Previously
declared information varieties, constructions, and enums are also regarded price sorts and
perform in the very same tactic. Also, Price kind variables can be produced at
the time of compilation and can be stored in stack memory. The garbage
collector is not able to access this stack for the reason that of this variable.

int x=21


Listed here the benefit 21 is saved in the stack memory spot.

Reference Sort variable

Reference Form variables are used by a reference that possesses a
reference or deal with to another object but not the exact item alone. Due to the fact
reference-variety variables depict the site aspects of that variable fairly
than the very same info by itself, assigning a particular reference variable to a different
just one, does not copy the facts. Instead, it generates a 2nd copy of the
reference variable, which relates to the identical unique locale of the
specific heap as the actual benefit. Reference Sort variables get saved in
different parts of memory named heap. It implies when a reference variety variable is
no lengthier utilized, it can be captioned for rubbish collection.

Examples of reference-style variables are
Lessons, Arrays,
Objects, Interfaces, Indexers, and so forth.


int iArray[] =new int[31]

In the earlier mentioned case in point with code, the area preferred for the 31 integers that
compose up the array is allotted on the heap.

Heap and Stack

Heap is utilized for dynamic memory allotment, and Stack is utilized for
static memory allotment, but both equally are stored in the RAM of personal computer.

Let’s focus on some extra benefit sort and reference sort variables.  

Class and Struct

is regarded as a variable of move-by-reference and Struct is thought of as a
variable of move-by-copy, it suggests that Class is a reference classification
variable and its object is built on the heap memory whereas the structure is a
price classification variable and its item is crafted on the stack memory.

Dynamic Knowledge Variety

dynamic details kind
notion delivers some new characteristics to C# 4. Having said that, Dynamic Form depicts that
you will be ready to store any type of benefit or info in the dynamic variable
because verifying of data form for dynamic groups of variables occurs at


I hope the previously mentioned posting on the differentiation of price style and reference
kind could assistance freshers or newcomers in the progress discipline. These
variables are a major element of database interaction for close-users.
