I am trying to flatten nested objects like this:
public class Book
{
public string Name { get; set; }
public IList<Chapter> Chapters { get; set; }
}
public class Chapter
{
public string Name { get; set; }
public IList<Page> Pages { get; set; }
}
public class Page
{
public string Name { get; set; }
}
Let me make an example. This is the data I have
Book: Pro Linq
{
Chapter 1: Hello Linq
{
Page 1,
Page 2,
Page 3
},
Chapter 2: C# Language enhancements
{
Page 4
},
}
The result I am looking for is the following flat list:
"Pro Linq", "Hello Linq", "Page 1"
"Pro Linq", "Hello Linq", "Page 2"
"Pro Linq", "Hello Linq", "Page 3"
"Pro Linq", "C# Language enhancements", "Page 4"
How could I accomplish this? I could do it with a select new but I've been told that a SelectMany would be enough.
myBooks.SelectMany(b => b.Chapters
.SelectMany(c => c.Pages
.Select(p => b.Name + ", " + c.Name + ", " + p.Name)));
