Convert a List<T> into an ObservableCollection<T>

问题

I have a List<T> which is being populated from JSON. I need to convert it into an ObservableCollection<T> to bind it to my GridView.

Any suggestions?

回答1:

ObservableCollection < T > has a constructor overload which takes IEnumerable < T >

Example for a List of int:

ObservableCollection<int> myCollection = new ObservableCollection<int>(myList);

One more example for a List of ObjectA:

ObservableCollection<ObjectA> myCollection = new ObservableCollection<ObjectA>(myList as List<ObjectA>);

回答2:

ObervableCollection have constructor in which you can pass your list. Quoting MSDN:

 public ObservableCollection(
      List<T> list
 )

回答3:

The Observable Collection constructor will take an IList or an IEnumerable.

If you find that you are going to do this a lot you can make a simple extension method:

    public static ObservableCollection<T> ToObservableCollection<T>(this IEnumerable<T> enumerable)
    {
        return new ObservableCollection<T>(enumerable);
    }
