Question

I have the following sample columns

ID  Comment    Analyzer  Incubator    Deanalyzer
--  -------    -------   ---------    ----------
23  Need Fast  5.6                    8.7

What I need is to show the results is the ID, Comments, then a count of
how many columns had values. So in this case count would be 2 as only Analyzer and Deanalyzer have values. This is what I have so far:

    var result = from tb in db.Reports
    where tb.Id == 23
    select new { ID = tb.ID, 
                 Comments = tb.Comments,
                 Count = .. 

                } 

Answer 1

It’s not clean but you could do:

var result = from tb in db.Reports
where tb.Id == 23
select new { ID = tb.ID, 
             Comments = tb.Comments,
             Count = (tb.Analyzer!= null ? 1 : 0) + (tb.Incubator != null ? 1 : 0) + (tb.Deanalyzer!= null ? 1 : 0)

            }

I wouldn’t use this if you have lots of columns.
