Linq FirstOrDefault

Question

I have the following LINQ query:

    Manager mngr = (from tr in DataContext.Manager
                    where tr.Name = \"Jones\").FirstOrDefault();
<         


        

Answer 1

You can use the SingleOrDefault extension method to express that the query only ever should return one result.

Manager manager = (from tr in DataContext.Manager 
                   where tr.ID = "2323").SingleOrDefault();

However it does not tell you whether you got 0 results or more than 1.
