how to add a constructor to a class

Question

how do I add a constructor method to a class that I created

I made a book class and I now need it to be a booktest that has a constructor that initializes the properties

this is my code:

using System;

class Book

{

public string Title { get; set; }

public string Author { get; set; }

public DateTime Date { get; set; }

public Book(string title, string author, DateTime date)

{

Title = title;

Author = author;

Date = date;

}

public override string ToString()

{

return String.Format("Title : {0}\nAuthor : {1}\nPublished : {2}", Title, Author, Date.Year);

}

}

class Program

{

static void Main()

{

Book b = new Book("radars adventure", "Nick james", new DateTime(1989, 1, 1));

Console.WriteLine(b);

Console.ReadKey();

}

}

}
