Structure with constructor in C#

Before some time , I have written basic introduction post about Structure in C#. In this blog post we are going to see how we can have constructor with Structure. As we all know structure is a value type so it stored on stack. So let’s create a structure like follow with constructor.
public struct Customer
    #region Fields

    public int CustomerId;
    public string FirstName;
    public string LastName;


    #region Constructor

    public Customer(int customerId, string firstName, string lastName)
        CustomerId = customerId;
        FirstName = firstName;
        LastName = lastName;

Here you can see I have created Stucture with parameter. As we all know structure is a value type so when initialize the it at that time we need to give values to its elements so that’s why default constructor without parameter is not supported in C#.

You can find whole discussion about that at stackoverflow at following link.

Now let’s create a object of structure in our console application like below.
class Program
    static void Main(string[] args)
        Customer customer = new Customer(1, "Jalpesh", "Vagdama");

Now once you run this application. It will print fields of customer structure as expected.


That’s it. Hope you like it. Stay tune for more!!.
