IQueryable efficiency

Question

Hi all,

I'm writing a repositoy now, returning IQueryable results. Does adding filters affect the efficiency? campring to write the clause in the linq.

Such as

IQueryable result = repository.GetAllBooks().Where(book => book.author =="Russell");

Thanks!

Answer 1

An equivalent LINQ statement would compile to the Where extension method that you use above so it should behave/perform in the same way.
