c# - 如何用列表初始化类？

Question

基本问题，但我无法在任何地方找到答案，我有 2 个类(class):

public class Book
{
    public int Id { get; set; }
    public string Category { get; set; }
    public string Title { get; set; }
    public IList<Chapter> Chapters{ get; set; }
}

public class Chapter
{
    public int Id { get; set; }
    public string Title { get; set; }
}

如何添加或初始化它？我试过:

 var books = new List<Book>();

        books.Add(new Book()
        {
            Id = 1,
            Category = "test",
            Title = "Book1 test",
            Chapters = new Chapter() { Id = 1, Title = "A"},
                       new Chapter() { Id = 2, Title = "B" }
        });

但我收到一个错误:无效的初始值设定项成员声明符？

Answer 1

我觉得你想要

Chapters = new List<Chapter>() 
               {
                  new Chapter() { Id = 1, Title = "A"},
                  new Chapter() { Id = 2, Title = "B" }
               }

代替:

Answers = new Chapter() { Id = 1, Title = "A"},
          new Chapter() { Id = 2, Title = "B" }

1. 您的Book 类没有名为Answers 的属性
2. 您需要创建一个新集合并将初始化(new Chapter() { ... })放入集合初始化器中。
