C＃向List <borrower>

Question

我有一个名为List<Borrower>的{​​{1}}，其中包含一个借款人名单＆＃39;名字和他们借来的书的名称。

当借款人从BorrowerList出列并从BorrowerQueue弹出一本书时会发生这种情况。

我想要发生的是，将BookStack和BorrowerQueue的值添加到此sample from msdn中的Bookstack。但是我不完全理解它是如何完成的。非常感谢帮助。

BorrowerList

目标：

 var reader = BorrowerQueue.Dequeue(); //person gets dequeued from line
 var books = BookStack.Pop(); // book gets popped from stack and associated to reader

 BorrowerList.Add(new Borrower(reader.ToString()) {}); // what to do here?

这是我{[name1, Book], [name2, Book] .... } 的课程：

Borrower

class Borrower : IEnumerable<Borrower> { private string name; private Book b; public Borrower(String n) { this.name = n; } public string getName() { return name; } public Book getBook() { return b; } public void setBook(Book b) { this.b = b; } } 上课：

Book

Answer 1

将您的属性getter和setter简化为标准属性。 C＃编译器会自动转换它们的get / set函数。你的课应该是这样的：

class Borrower
{
    public string Name { get; }
    public Book Book { get; set; }

    public Borrower(string n)
    {
        //Since C# 6.0, read-only properties can be set in the constructor
        this.Name = n; 
    }
}

现在您需要做的就是在您出队时设置Book属性：

var reader = BorrowerQueue.Dequeue(); //person gets dequeued from line
var books = BookStack.Pop(); // book gets popped from stack and associated to reader
BorrowerList.Add(new Borrower(reader.ToString()) { Book = book });
