C# Sorting a List of Objects by Name and Coord

Question

to set the scene, I have a list of objects. Each object contains a name, and a point consisting of an x coordinate and a y coordinate.

I currently have the list sorted to group up the object's name in alphabetical order. Now I want the same named objects to be ordered by descending or ascending x coordinates.

What is inside the list now:
- BP301 (5, 6)
- BP301 (-3, 2)
- BP301 (0, 4)
- BP301 (5, 6)
- BP302 (10, 7)
- BP302 (10, 7)
- GP001 (8, 3)
What I want inside the list:
- BP301 (-3, 2)
- BP301 (0, 4)
- BP301 (5, 6)
- BP301 (5, 6)
- BP302 (10, 7)
- BP302 (10, 7)
- GP001 (8, 3)

Hopefully my question is clear enough

Can you show the code you are using now to store and sort these objects? — Steve

Have you considered using LINQ?

Rough example given no code, so I'm assuming an IEnumerable<T> compatible list:

var sortedList = list.OrderBy(i => i.Name).ThenBy(i => i.X).ThenBy(i => i.Y);

Yes that worked, thank you. I need to look more into LINQ. I'm bad with list sorting.

Yeh there's a bunch of fun stuff you can do, sort ascending, sort descending, group and so on.
