Sort a list by className Alphabetic order

Question

I'm doing some exercise on Unity/C#, and for one of them I have a list that contain some inherited classes.

    public List<Item> items = new List<Item>();

each Item is an inherited class like PowerUp,ConceptArt,Bonus who all iherit from Item...

I would like to, sort that list using the name of the item class.

Basically if i have list

myList = { Bonus,ConceptArt, PowerUp, PowerUp,ConceptArt }

if I sort it, the output would be :

myList = { Bonus,ConceptArt, ConceptArt, PowerUp,PowerUp}

How do I do that?

I don't know if I explained myself clearly. If i need to edit, tell me :)

thx :)

`myList = myList.OrderBy(item => item.Name).ToList()` or something similar? — Jon Skeet, Sep 23 '15 at 10:35

I don't think this is a duplicate as that question is trying to sort based on a property of the list type, the OP is trying to sort based on the type of the object itself. — rcbevans, Sep 23 '15 at 10:42
For future reference, the term you are referring to is inherit / inherited, not herit / herited. — Darren Young, Sep 23 '15 at 10:47

Try this:

items = items.OrderBy(x => x.GetType().Name).ToList();

I m doing maybe something bad, but it looks like myList.orderBy don't exist in Unity. – Crocsx Sep 23 '15 at 10:53
How is this related to Unity? – Yacoub Massad Sep 23 '15 at 10:55
Make sure that you have imported the `System.Linq` namespace at the start of your c# file. E.g. `using System.Linq;` – Yacoub Massad Sep 23 '15 at 10:57
You right, I didn't had the using System.Linq; Thx :) – Crocsx Sep 23 '15 at 11:05

To sort in place, without creating a new list:

  myList.Sort((Comparison<Item>) 
    ((left, right) => String.Compare(left.GetType().Name, right.GetType().Name)));

To check/test:

  String report = String.Join(", ", myList
    .Select(item => item.GetType().Name));

  Console.Write(report);
