Hi,
As per MSDN
Whenever a class or struct is created, its constructor is called. A class or struct may have multiple constructors that take different arguments. Constructors enable the programmer to set default values, limit instantiation, and write code that is flexible and easy to read.
Please refer https://msdn.microsoft.com/en-in/library/ace5hbzh.aspx for more details
So practical use of the constructor is set to initial value and run some initial code that can be use in later called methods. Example, we can set value of readonly variable at declaration or in class constructor.

hope this will help you.

We can say Constructor Is Special Member Function Of Class Having name same as class name
A class may have multiple constructors that take different arguments. Constructors enable the programmer to set default values, limit instantiation, and write code that is flexible and easy to read.

When we create a object of class constructor gets automatically called.
There Are Three Types Of Constructors
1]Parameterless constructor
when You write any class and creates its object and provide parameterless constructor but donot provide any parameters then parameterless constructor gets called.

2]Parameterised constructor
when You write any class and creates its object and provide Parameterised constructor but provide any parameters then parameterised constructor gets called.

2]Default constructor
when You write any class and creates its object and do not provide constructor Default constructor gets called.

Hope this will help You

Broadly speaking, a constructor is a method in the class which gets executed when its object is created. Usually, we put the initialization code in the constructor.

Constructor mainly is use for create the variables and provide the space into memory.

Hi,
I example which I think where we use Constructor is, where I want to set some default values on creating the instance of class.
Lets say,

class Bank
{
public decimal MinBalance {get;set;}
public decimal AccountNo{get;set;}

public Bank(decimal minbalance)
{
MinBalance = minbalance;
}
}

Bank boi = new Bank(1000);
Hope this will explain where and why we use construtor. Here I have a bank where it is mandatory to have balance to be maintained. So this parameterized constructor will take care of passing min balance to the bank object. Hope this example will help you to some extent.
