Question

I need to do a LINQ2DataSet query that does a join on more than one field (as

var result = from x in entity
join y in entity2 
       on x.field1 = y.field1          


        

Answer 1

you could do something like (below)

var query = from p in context.T1

        join q in context.T2

        on

        new { p.Col1, p.Col2 }

        equals

         new { q.Col1, q.Col2 }

        select new {p...., q......};
