意外丢失，很重要的内容全无，非常无语，草搞箱也不见了。现在快速恢复一些内容

EuropeanCastle.Books 类库，给所有书类添加了 BookBase基类

    public abstract class BookBase : BindingableBase
    {
        private string name;

        private Catalogue catalogue = new Catalogue();

        protected BookBase()
        {

        }


        public string Name
        {
            get { return name; }
            set { SetProperty(ref name, value); }
        }

        public Catalogue Catalogue
        {
            get { return catalogue; }
            set { SetProperty(ref catalogue, value); }
        }
    }

FrameworkDesignGuidelinesBook 类得到更新，添加了另一个内部类初始化这个类的目录信息，也继承了新类

    public class FrameworkDesignGuidelinesBook : BookBase
    {
        private FrameworkDesignGuidelinesBookInitCatalogue initCatalogue = new FrameworkDesignGuidelinesBookInitCatalogue();

        public FrameworkDesignGuidelinesBook()
        {
            Name = ".NET 设计规范约定、惯用法与模式(第二版)";
            InitCatalogue();
        }

        public override string ToString()
        {
            return Name;
        }

        private void InitCatalogue()
        {
            Catalogue.Add(initCatalogue.NewChapterOne());
            Catalogue.Add(initCatalogue.NewChapterTwo());
            Catalogue.Add(initCatalogue.NewChapterThree());
            Catalogue.Add(initCatalogue.NewChapterFour());
            Catalogue.Add(initCatalogue.NewChapterFive());
            Catalogue.Add(initCatalogue.NewChapterSix());
            Catalogue.Add(initCatalogue.NewChapterSeven());
            Catalogue.Add(initCatalogue.NewChapterEight());
            Catalogue.Add(initCatalogue.NewChapterNine());
        }
    }

添加了 FrameworkDesignGuidelinesBookInitCatalogue 内部类

内部类

更新了 WpfProgrammingValuables2012Book 类

这里写图片描述

添加了绑定 BindingableBase 基类，所有类都继承了这个基类

    public class BindingableBase : INotifyPropertyChanged
    {

        protected BindingableBase()
        {

        }

        public event PropertyChangedEventHandler PropertyChanged;

        protected void OnPropertyChanged(PropertyChangedEventArgs e)
        {
            var propertyChanded = PropertyChanged;
            if (propertyChanded != null)
            {
                PropertyChanged(this, e);
            }
        }

        protected void SetProperty<T>(ref T item, T value, [CallerMemberName]string propertyName = null)
        {
            if (!EqualityComparer<T>.Default.Equals(item, value))
            {
                item = value;
                OnPropertyChanged(new PropertyChangedEventArgs(propertyName));
            }
        }
    }

控制台项目也更新代码

        static void Main(string[] args)
        {
            var frameDesGuidlinesBook = new FrameworkDesignGuidelinesBook();
            foreach (var item in frameDesGuidlinesBook.Catalogue.GetEnumeratorTreeView())
            {
                Console.WriteLine(item);
            }
            Console.WriteLine();

            Console.ReadLine();
        }

输出有了层化，得益于 Catalogue 类添加了自定义迭代方法

        public IEnumerable<string> GetEnumeratorTreeView()
        {
            foreach (var chapter in Items)
            {
                var paddingLeft = "    ";//左填充
                yield return chapter.ToString();//首层，章节
                foreach (var section in chapter.Sections)
                {
                    yield return paddingLeft + section.Name;//第二层
                    foreach (var nestSection in section.Sections)
                    {
                        yield return paddingLeft + paddingLeft + nestSection.Name;//第三层
                    }
                }
            }
        }

输出结果
