Custom sorting with LINQ

Question

It seems that i\'m missing something trivial.

Anyway, here it goes:

var order = new[]{1,3,2};
var foos = new[]{new Foo{Id=1}, new Foo{Id=2}, new Fo         


        

Answer 1

Is this what you are trying to do?

foos.OrderBy(f => order[f.Id-1]);

If you foreach now on the output of that, printing the ID, you get: 1,3,2
