Return anonymous type inside Where method

I know that to return an anonymous type I can do this:

var test  = from c in list
            where c.SomeField > 200
            select new { c.SomeField, c.AnotherField };

And that's ok.

Now, I'd like to now how to return this anonymous type doing the same thing but using the Where method. Something like:

var test = list.Where((SomeType c) => { if (c.SomeField > 200) 
                                        return new { c.SomeField, c.AnotherField } });

Is there any way of doing it using the Where method?

Thank you!

Where is not designed for this. Where expects a delegate that takes an object and returns a bool. So, returning an anonymous type in Where is not possible and doesn't make sense.

You can only filter your items with Where and then do the projection with Select

var test = list.Where(c=> c.SomeField > 200)
               .Select(c => new { c.SomeField, c.AnotherField });

Btw this is equivelant of your first query since it will be translated into this.

Alternatively, if you are working with List<T>, you can use List<T>.FindAll method to get all the items that matches with your predicate.
