Question

I need to sort a list, by X and Y. I read some on other questions to sort X and Y, but I didn’t understand the:

List<SomeClass>() a;
List<SomeClass> b = a.OrderBy(x => x.x).ThenBy(x => x.y).ToList();

I mean, x => x.x gives undeclared variable error.

Question is: How to sort by X and Y in a list, or: What variable to have instead of x => x.x????

edit: right, my list is like this:

List<Class1> MapTiles;

and in class: int ID, int X, int Y

Thanx.

Answer 1

C# is case sensitive. You need

// Note the capital letters
List<SomeClass> b = a.OrderBy(item => item.X).ThenBy(item => item.Y).ToList();
