List of Days irrespective of time

debugcn 에 게시 Dev

Ankit

I have an ObservableCollection of a Type with a property "StartDate" of type DateTime. I want to create a list of Unique Days irrespective of the time. I know I can do this iterating over the list and comparing day,month,year of a date. But is there any cleaner & simpler way of doing this? may be through LINQ or something?

DateTime has a property Date that doesn't contain the time of day, just the date.
First select it and then use Distinct to get each date only once.

var uniqueDays = collection.Select(x => x.StartDate.Date).Distinct();
