Umbraco 7 LINQ to filter Model children on date range

Question

I have a collection of articles in Umbraco 7 which span multiple years and wanted to write a simple LINQ query to get items for the current year:

var press =  Model.Content.Children.Where(w => Convert.ToDateTime(w.GetPropertyValue("publicationDate")) >= new Date(1,1,2018));

This results in the error:

Delegate 'System.Func' does not take 1 arguments.

I'm contemplating just bunging the data in a list of T - unless someone can steer me in the right direction with filtering on Umbraco content nodes?

Thanks in advance.

Answer 1

I'm thinking something like this looks more "correct" to me, but it's untested. One thing to note is the way I make sure to get the property as DateTime directly from Umbraco. And also I figured comparing it to a DateTime instead of a Date might make a difference.

var press =  Model.Content.Children.Where(w => w.GetPropertyValue<DateTime>("publicationDate") >= new DateTime(2018,1,1));
