is it possible to have a conditional field in an anonymous type

Question

i have some code that looks like this and creates a list from an existing collection

 var items = items.ConvertAll(r => new
            {
                         


        

Answer 1

No, you can't, mostly since it would make the anonymous class different in different executions and the class couldn't be type checked.

I'd recommend setting your Start date to null instead of a default, and checking for that later in your code.
