Answer 1

If you just want it sorted, I’d use List.Sort().

If you want to swap, there is no built in method to do this. It’d be easy to write an extension method, though:

static void Swap<T>(this List<T> list, int index1, int index2)
{
     T temp = list[index1];
     list[index1] = list[index2];
     list[index2] = temp;
}

You could then do:

list.Swap(0,2);
