Hi All,
I am working on an MVC 3 project .. just updating a few things here and there..

Is it possible to Use FirstOrDefault followed by Where clause? at the moment it does not let me. Is there any possible solution to go around this?

Example ...

C#

var car = carContext.Vehicles.FirstOrDefault(x =>x.Reg = reg).Where(x =>x.manufacturere == "BMW")

is there a way around this??

Solution 2

var car = carContext.Vehicles.FirstOrDefault(x =>x.Reg == reg && x.manufacturere == "BMW")

That will select the first where the reg and manufacturer match the parameters supplied.

Solution 1

No.
FirstOrDefault returns a single value, not a collection - so Where (which operates only on collections) has nothing to work with.
You can use it the other way round though: Where(...).FirstOrDefault()
