创建一个列表 <Book> c＃控制台应用程序

Question

I want to create a List that holds a couple of books with the book title, authors name and year of publication. example: ( AuthorLastName, AuthorFirstName, “The book title”, year.)

I know how to create List<int> , for example:

class Program
{
    static void Main()
    {
    List<int> list = new List<int>();
    list.Add(10);
    list.Add(20);
    list.Add(25);
    list.Add(99);
    }
}

But the problem is, if I want to create a list of books, I can't simply make a list<string> or list<int> because I want it to contain strings and int's (as the example above).

So, Can anyone explain how I can make a List of books?

Answer 1

You need to create a class called Book that contains the properties you want to have. Then you can instantiate a List<Book> .

Example:

public class Book
{
   public string AuthorFirstName { get; set; }
   public string AuthorLastName { get; set; }
   public string Title { get; set; }
   public int Year { get; set; }
}

And then, to use it:

var myBookList = new List<Book>();
myBookList.Add(new Book { 
                         AuthorFirstName = "Some", 
                         AuthorLastName = "Guy", 
                         Title = "Read My Book", 
                         Year = 2013 
                        });

Answer 2

You need to define your class:

    public class Book 
    {
       public string Author { get; set; }
       public string Title { get; set; }
       public int Year { get; set; }
    }

Then you can make a list of them:

var listOfBooks = new List<Book>();

Answer 3

Do something like this

            public class Book
            {
                public string AuthorLastName { get; set; }
                public string AuthorFirstName{ get; set; }
                public string Title{ get; set; }
                public int Year { get; set; }
            }

            List<Book> lstBooks = new List<Book>();
            lstBooks.Add(new Book()
            {
                AuthorLastName = "What",
                AuthorFirstName = "Ever",
                Title = Whatever
                Year = 2012;
            });
