Gor*_*ric 4 c# class list generic-list
我发现了一个关于在类中使用List的代码示例.有些代码我不理解.Name和Description字段在List defination中有值,但Album字段没有值.(
new genre { Name = "Rock" , Description = "Rock music", Album?? }
).为什么？
public class Genre
{
public string Name { get; set; }
public string Description { get; set; }
public List<Album> Albums { get; set; }
}
public class Album
{
public string Title { get; set; }
public decimal Price { get; set; }
public Genre Genre { get; set; }
}
var genre = new List<Genre>
{
new genre { Name = "Rock" , Description = "Rock music" },
new genre { Name = "Classic" , Description = "Middle ages music" }
};
new List<Album>
{
new Album { Title = "Queensrÿche", Price = 8.99M, Genre = genre.Single(g => g.Name == "Rock") },
new Album { Title = "Chopin", Price = 8.99M, Genre = genre.Single(g => g.Name == "Classic") }
};
