c# - linq multi left join to same property -

-

is possible write linq query? (in .net 3.5)

select tt.id      ,tt.detailscount      ,ttdmx.detailorder      ,ttdmx.detailtype      ,ttdm1.detailorder      ,ttdm1.detailtype      ,ttdm2.detailorder      ,ttdm2.detailtype test.testtable tt left join test.testtabledetails ttdmx on tt.id = ttdmx.causeid      , tt.maxcausedetailorder = ttdmx.detailorder left join test.testtabledetails ttdm1 on tt.id = ttdm1.causeid      , tt.maxcausedetailorder - 1 = ttdm1.detailorder left join test.testtabledetails ttdm2 on tt.id = ttdm2.causeid      , tt.maxcausedetailorder - 2 = ttdm2.detailorder

the classes this:

public class test {   public int id {get;set;}   public ilist<testdetails> details {get;set} }

and

public class testdetails {   public int id {get;set;}   public int detailorder {get;set;}   public int detailtype {get;set;} }

i tried queryover can't join same property twice.

the easiest way write:

... ttdmx in db.testtabledetails.where(x =>      tt.id == x.causeid &&      tt.maxcausedetailorder == x.detailorder).defaultifempty() ...

this translated sql left join
