'Recursive' LINQ calls
- by Sir Psycho
Hi,
I'm trying to build an XML tree of some data with a parent child relationship, but in the same table.
The two fields of importance are
CompetitionID
ParentCompetitionID
Some data might be
CompetitionID=1,
ParentCompetitionID=null
CompetitionID=2,
ParentCompetitionID=1
CompetitionID=3,
ParentCompetitionID=1
The broken query I have simply displays results in a flat format. Seeing that I'm working with XML, some sort of recursive functionality is required. I can do this using recursion, but would like to see the linq version. Any help appreciated.
var results =
from c1 in comps
select new {
c.CompetitionID,
SubComps=
from sc in comps.Where (c2 => c2.CompetitionID == c1.CompetitionID)
select sc
};
