Convert a List<T> into an ObservableCollection<T>
提问by raghu_3
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.
我有一个List<T>从 JSON 填充的。我需要将其转换为 anObservableCollection<T>以将其绑定到我的GridView.
Any suggestions?
有什么建议？

ObservableCollection < T > has a constructor overloadwhich takes IEnumerable < T >
ObservableCollection < T > 有一个构造函数重载，它接受 IEnumerable < T >
Example for a List of int:
列表示例int：
ObservableCollection<int> myCollection = new ObservableCollection<int>(myList);
One more example for a List of ObjectA:
列表的另一个示例ObjectA：
ObservableCollection<ObjectA> myCollection = new ObservableCollection<ObjectA>(myList as List<ObjectA>);

The Observable Collection constructor will take an IList or an IEnumerable.
Observable Collection 构造函数将采用 IList 或 IEnumerable。
If you find that you are going to do this a lot you can make a simple extension method:
如果你发现你要做很多事情，你可以做一个简单的扩展方法：
public static ObservableCollection<T> ToObservableCollection<T>(this IEnumerable<T> enumerable)
{
return new ObservableCollection<T>(enumerable);
}
