C# Linq - Cannot implicitly convert IEnumerable to List

Question

I have a List defined like this :

public List AttachmentURLS;

I am adding items to the list like this:

instructio         


        

Answer 1

The Where method returns an IEnumerable. Try adding

.ToList()

to the end like so:

instruction.AttachmentURLS = curItem.Attributes["ows_Attachments"]
  .Value.Split(';').ToList()
  .Where(Attachment => !String.IsNullOrEmpty(Attachment))
  .ToList();
