Loop through array in linq query

Question

Hi all I have a query using Linq that returns a set of records, one of which is the country id, I also have an array of desired countries. Is there a way of either looping through the countries array and seeing if the id is in the results, i want to do something like this

results = from r in results 
where
//jump to my c# array
for(int x = 0;x < array.count; x++)
{
r.countryId.ToString().Contains(array[x]) 
}
select r

thanks

Try this

var list  =  from r in results
             where array.Contains(r.countryId.ToString()) 
             select r;
