Constructors in C#.NET Part 1 | C#.NET Tutorial | Clcoding

It's a special method present under a class responsible for initializing the variable of that class.

The name of a constructor method is exactly the same name of the class in which it was present and more over it's a non-value returning method.

Each and every class requires this constructor if we want to create the instance of that class.

class Test

{

int i ;

} 

Test obj = new Test();  // Valid

⟶ It's the responsibility of a programmer to define a constructor under his class and if he fails to do so, on behalf of the programmer an implicit constructor gets defined in that class by the compiler.

 class Test

{

int i ; string s; bool b;

public Test ()

{

i = 0;  // Initializing the variables

s = null;

b = false;

}

}  

Implicitly defined constructors are parameter less and these constructor are also known as default constructors.

Implicitly defined co0nstructor are public.

We can also defined a constructor under the class and if we define it we can call it as explicit constructor and explicit constructor can be parameter less or parameterized also.
