Converting an Object List to a String List [duplicate]

Question

What's a better way to write the following? Can I do it with a Lambda expression?

List<string> managerList = new List<string>();
foreach (Manager m in matchedManager)
{
    managerList.Add(m.FullName);
}

Yes you can use LINQ. Like this:

List<string> managerList = matchedManager.Select(m => m.FullName).ToList();

I thought so, trying to figure out why I'm getting Object reference not set to an instance of an object errors on both.

@NathanMcKaskle Are you sure matchedManager is non-null?

Positive, I checked that.

you may have null items in matchedManager ... try matchedmanager.Where(i=>i!=null).Select(m=>m.FullName)
