I have a method that returns a List<string>
and I'm trying to pass that to the AddRange(Object[])
method of a ComboBox
.
How can I convert my List<string>
to Object[]
?
I suppose I could do a foreach
but I'd rather use the AddRange(Object[])
as it's faster (and produces less code).
EDIT
The following works fine:
var list = new List<string>();
object[] array = list.ToArray<object>();
comboBox.AddRange(array);
However, on another note, any reason why I would want to perform the above instead of:
var list = new list<string>();
comboBox.AddRange(list.ToArray<object>());
Pass the List<String> as a parameter to the constructor of a new ArrayList<Object> . List<Object> objectList = new ArrayList<Object>(stringList);
You can do it using ToArray
generic method:
var list = new List<string>();
object[] array = list.ToArray<object>();
You don't even need Cast<object>
, because ToArray
takes IEnumerable<T>
which is covariant on generic type parameter.
