Question

I have an entity collection tied to another entity (navigation property) I will always have one but for some reason it brings it back as a collection. I need to be able to change one property on this object, the DateViewed property.

var test = _personDetail.CurrentPerson.RecentlyViewed;

is there a way to use this new test object in a lambda expression to change the DateViewed property to DateTime.Now

Answer 1

Note, I am not 100% certain what you are asking – ie which part comes back as collection, and what RecentlyViewed is (did you mean DateViewed as you mention elsewhere? Taking a guess here – let me know if this isn’t what you meant.

If you know there will always be one and only one item in the CurrentPerson collection, you can use Single() – ie:

_personDetail.CurrentPerson.Single().DateViewed = DateTime.Now;
