c# - Creating a List c# console application

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

您需要创建一个包含您想要拥有的属性的class调用。Book然后你可以实例化一个List<Book>.

例子：

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

然后，使用它：

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

Answer 2

你需要定义你的类：

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

然后你可以列出它们：

var listOfBooks = new List<Book>();

做这样的事情

            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;
            });
