SQL Select Where In converted to Linq

Question

I am trying to select from where in out of the database using Linq. The query I would be trying to reproduce is:

   "Select * From Avatars Where userId IN (1, 2, 3)"

How can this be written in lambda if I have a List of userIds.

I am stuck where the !! are and have a List of userIds:

context.avatars.Where(a => a.userId == !!(userIds)!! )

You can use Contains method:

var result=context.avatars.Where(a => userIds.Contains(a.userId));

Or Any:

 var result=context.avatars.Where(a => userIds.Any(e=>a.userId==e));

something like :

context.avatars.Where(a => new[] { 1, 2, 3 }.Contains(a.userId));
