Hi everybody,
first of all thanks to the guys who replied me.
I'll describe a little more my problem so maybw someone can give me an
hint helping me to reach "the idea" I'm lacking.
class Bar {
Foo Foo { get; set; }
}
abstract class Foo { }
class A : Foo { }
class B : Foo { }
class C : Foo { }
Given some criteria from the application user I need to:
1. select all the A matching the criteria
2. select all the B matching the criteria
3. select all the C matching the criteria
4. perform a UNION on them
5. select all the Bar whose .Foo is in the selection coming from 4 via a JOIN
Could you suggest me any way to do such stuff using LINQ?
Thanks in advance,
Giulio
