c# - Convert List(of object) to List(of string)

Question

Is there a way to convert a List(of Object) to a List(of String) in c# or vb.net without iterating through all the items? (Behind the scenes iteration is fine – I just want concise code)

Update: The best way is probably just to do a new select

myList.Select(function(i) i.ToString()).ToList();

or

myList.Select(i => i.ToString()).ToList();

Answer 1

Not possible without iterating to build a new list. You can wrap the list in a container that implements IList.

You can use LINQ to get a lazy evaluated version of IEnumerable<string> from an object list like this:

var stringList = myList.OfType<string>();
