LINQ, Left Join, Only Get where null in join table
- by kmehta
Hi. I am trying to do a left outer join on two tables, but I only want to return the results from the first table where the second table does not have a record (null).
var agencies = from a in agencyList
join aa in joinTable
on a.AgencyId equals aa.AgencyId into joined
from aa in joined.DefaultIfEmpty()
where aa == null)
select a;
But this does not exclude the non null values of aa, and returns all the records just the same as if the 'where aa == null' was not there.
Any help is appreciated. Thanks.
