Question

I am trying to determine if the current user has voted on a ProjectDoc. This query gives me a value of 1. There is no value in the ProjectDocVote table that matches the UserID. The ViewBag.CurrentUserID value is correct.

 var count = Model.Project.ProjectDoc
       .Where(a => a.Current == true && a.DocType == "Cover")
       .Select(v => v.ProjectDocVote
              .SingleOrDefault(u => u.UserID == ViewBag.CurrentUserID)
       )
       .Count();

How do I fix this query?

Answer 1

var count = Model.Project.ProjectDoc
   .Where(a => a.Current == true 
            && a.DocType == "Cover"
            && a.ProjectDocVote.Any(v => v.UserID == ViewBag.CurrentUserID))
   .Count():
