LINQ multiple order by

Question

I have created a function that has the follwing parameter:

List>> orderBy = null

T

Answer 1

Two problems; firstly, ThanBy should be ThenBy; secondly, ThenBy is only available on the generic type, IOrderedQueryable.

So change to:

        IOrderedQueryable temp = null;
        foreach (Expression> func in orderBy) {
            if (temp == null) {
                temp = catalogProducts.OrderBy(func);
            } else {
                temp = temp.ThenBy(func);
            }
        }

and you should be sorted.
