query ilist with linq

Question

I would like to get data with linq from ilist which has type of one class - for example - iList - everything I know, that in this iList are saved emails and names, but this iList has no string type, but this class. How can I get them? It would be great to put this data to my own List Any hint how to do that?

Answer 1

IList<MyNameAndEmailClass> myList = GetMyList();
var emailList = myList.Select(x => x.EmailAddress).ToList();

emailList will now contain only the email addresses.

Answer 2

Is this what you want?

var result = list.OfType<SomeType>()
