Linq FirstOrDefault

Question

I have the following LINQ query:

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


        

Answer 1

You are using an ID for the where condition, I think you should've already guaranteed that this query returns only one result.

If your problem is having no result please check the usage of FirstOrDefault() from MSDN title.

            int[] numbers = { };
            int first = numbers.FirstOrDefault();
            Console.WriteLine(first);

            /*
             This code produces the following output:

             0
            */
