Class vs Structure

Structures:

These are also user defined types similar to a class under which you can define all the members what we can define under class.

class	structure
it is reference type	it is value type
it wasn’t faster in access than a structure	these are faster in access
to create a object we required to use a new operator which is mandatory	we can create the object of it without using new operator also
get its memory allocated on managed heap which provides automatic memory management with the help of garbage collector	Gets it memory allocated on stack which does not provides dynamic memory allocation. garbage collector can’t come into picture
it supports inheritance	it does not support inheritance
a programmer can define a default constructor or will be defined by the compiler if  no constructor exists in the class	a default constructor can only be defined by the compiler a programmer can never do it.
can contains variables declared and initialized	can contain variable declaration but can’t be initialized should be initialized either using object of the structure or constructor of the structure.

Structure Example

namespaceConsoleApplication2

{

    structmystruct

    {

        intx;

        publicmystruct(int x)

        {

            this.x = x;

        }

        publicvoid Test()

        {

            Console.WriteLine("Method" + x);

        }

        publicstatic voidMain()

        {

            mystructm1;

            m1.x = 100;

            m1.Test();

            mystructm2 = new mystruct(200);

            m2.Test();

            Console.ReadKey();

        }

    }

}

Output:

Method 100

Method 200
