Question

Entity Framework has an associated Repository that provides built in functions for standard operations. One of these functions is a generalized Get(filter, orderby, includeList) method. I know how to use the filter and includeList, but I’ve not figured out how to use the orderby parameter. The orderby parameter is given as:

Func<IQueryable<TEntity>, IOrderedQueryable<TEntity>> orderBy = null

and the evaluation is:

     IQueryable<TEntity> query = DbSet;

     if (orderBy != null) {
        return orderBy(query).ToList();
     } else {
        return query.ToList();
     }

Any hints or examples will get me started
Thanks.

Answer 1

Maybe like so:

Func<IQueryable<SomeEntity>, IOrderedQueryable<SomeEntity>> orderBy
    = q => q.OrderBy(e => e.SomePropertyOfSomeEntity);
