Linq query return true or false

Question

I have a query where it should return TRUE or FALSE.

var query = from c in db.Emp
            from d in db.EmpDetails 
            where c.ID == d.ID &&         


        

Answer 1

If I understand you correctly you want to get true if one of the results of the query matches all conditions. In that case try something like this:

var found =
    (from c in db.Emp
    from d in db.EmpDetails
    where c.ID == y.ID && c.FirstName == "A" && c.LastName == "D"
    select c).Any();

this.result = found.ToString();
