Linq expression throws an ArgumentNullException

Question

GetSpecialNodes returns null sometimes. When it does, I get an ArgumentNullException thrown. Is there an elegant way of handling (a change to the linq expression) this besides calling GetSpecialNodes before running the Linq expression and doing a null check?

var nodes = (from HtmlNode node in document.GetSpecialNodes() select node);

Answer 1

May be

var nodes = (document.GetSpecialNodes() ?? new List<HtmlNode>()).ToList<HtmlNode>()
