Question

Seems like I may have missed something simple in the syntax, but I’d like to get the results of FirstOrDefault from a linq statement directly without having to store the IEnumerable in a temporary variable first. Something like this:

var bestCar = from c in cars
              orderby c.Price
              select first c

I know the first keyword doesn’t actually exist but illustrates what I’d like to do. I also know I can wrap the from…select statement in parenthesis and call FirstOrDefault directly but I think the above syntax is cleaner and easier to read.

Answer 1

Enumerable.FirstOrDefault is one of the extension methods in the Enumerable class which does not have a corresponding LINQ syntax element. The only way to bind to this method is via method call syntax.

You can avoid the temporary by doing the follownig

var bestCar = (from c in cars
              orderby c.Price
              select c).FirstOrDefault();
