List<T> from property in List<T>

I wasn't able to find much about how to do this. I'm probably not getting the terminology right.

I have a list of objects:

class Cat()
{
   public string Name { get; set; }
}

List<Cat> cats = new List<Cat>();

cats.add(new Cat() { Name = "Felix" } );
cats.add(new Cat() { Name = "Fluffy" } );

How do I get a list of strings from the Name 开发者_C百科property so it looks like this:

{ "Felix", "Fluffy" }

The LINQ Select operator is your friend:

cats.Select(c => c.Name).ToList()

I am using ToList() to avoid lazy evaluation and to ensure you have an IList to work with.

---

var names = cats.Select(c => c.Name);

But if you still need a list use

List<string> names = cats.ConvertAll(c => c.Name);

---

cats.Select(x => x.Name).ToList()

---

cats.Select(cat => cat.Name).ToList();

or

(from cat in cats select cat.Name).ToList();

If you don't actually need the List as an output, you can leave off the .ToList()

---

If you're not allowed (or don't want to) use var, extension methods and Linq or need a list of strings:

List<string> names = cats.ConvertAll(cat => cat.Name);

---

using linq:

var names = cats.Select(x => x.Name).ToList();

---

var listOfNames = (from c in cats
                   select c.Name).ToList();

---

Try this:

cats.Select(e => e.Name).ToArray();

Im pretty new with LINQ so I dont guarntee that works.

Also, add System.Linq namespace:

using System.Linq;

---

cats.Select(cat => cat.Name).ToList()

---

var names = (from cat in cats
             select cat.Name).ToList();
