Add elements from IList to ObservableCollection

Question

I have an ObservableCollection, and I\'d like to set the content of an IList to this one. Now I could just create a new instance of the collection..:

public         


        

Answer 1

If you do want to instantiate an observable collection and want to add a new range into Observable collection you can follow the following method I have tried:

var list = new List();
            list.AddRange(order.ItemTransactions.ToShortTrans());
            list.AddRange(order.DealTransactions.ToShortTrans());
            ShortTransactions = new ObservableCollection(list);

in this way you can add the range into ObservableCollection without looping.
