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

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

var query = from o in order
            join foo in foos on o equals foo.Id
            select foo;

var foos2 = query.ToArray();
