How can I sort ObservableCollection? [duplicate]

Question

I've tried:

Persons = from i in Persons orderby i.Age select i;

But I cant convert Linqs System.Linq.IOrderedEnumerable to ObservableCollection<Person>.

Answer 1

You just need to create a new instance of it.

Persons = new ObservableCollection<Person>(from i in Persons orderby i.Age select i);

Answer 2

An ObservableCollection can take in an IEnumerable<T> (i.e, in this instance, your IOrderedEnumerable) from it's constructor:
