Question

I’m trying to get a somewhat basic LINQ query but can’t figure out all conditions. yrs could equal several years like “2009,2008,2007” or is could equal “%”, for a wildcard. This query works for “2009,2008,2007” but does not work for the wildcard. How can I make it work for both conditions?

var results = (from a in db.t_harvest_statistics
                       where yrs.Contains(a.year) 
                       orderby a.id
                       select new { a.id, a.year, a.unit_number }).ToList();

Try this:

var results = (from a in db.t_harvest_statistics
                       where yrs.Contains(a.year) || yrs == "%"
                       orderby a.id
                       select new { a.id, a.year, a.unit_number }).ToList();
