Accepted answer
Yes, you use Contains:
db.Products.Where(product => myFields.Contains(product.Category))
aka
from product in db.Products
where myFields.Contains(product.Category)
select product
score:0
In theory you would use contains:
var productList = from product in context.Products
where myfields.contains(product.category)
select product
However you'll need to test this - I seem to recall there being a bug in the Linq2Sql optimizer when trying to deal with List<> and array values being used like this (it may have only occured if you tried to cast them as IQueryable)
score:1

To benefit the other random people that may arrive here via Bing (or any of the other search engines): Linq-To-Entities does not support the .Contains method in the current version. However, with a simple extension method, you can do so:
