Question

For example have this table:

Name | BodyType
----------------
John  | 1
Ted   | 2
Daniel| 3
George| 4

I my app i check “1” “2” and “3” checkbox. And i should find 3 rows (John, Ted, Daniel) and NOT George. How can i get this query in LINQ? (not use where p.BodyType!=4)
Use logic OR

var all = dataContext.Users;
foreach (searchParameter in search)
  ...?

Answer 1

Put the required IDs into a List<int> and then Contains:

var bodyTypes = GetBodyTypesFromSearchParameters();
var query = dataContext.Users.Where(user => bodyTypes.Contains(user.BodyType));
