Question

I have three tables in my database:

What I want is to get items from the table wedstrijden like this:

int id = 3;
var wedstrijden = from w in db.wedstrijden 
                  where w.teams.teamleden.gebruikersid == id 
                  select w;

Unfortunately i get the following error:

Compiler Error Message: CS1593: Delegate
‘System.Func’ does not take 1
arguments

Does anyone have a clue what’s causing the error or where i can find the answer to my question?

Answer 1

The property wedstrijden.teams.teamleden is an enumerable so you have to check each item individually:

int id = 3;
var wedstrijden = from w in db.wedstrijden 
                  where w.teams.teamleden.Any(t => t.gebruikersid == id)
                  select w;
