c# - Linq IN Operator

I've tried searching for this but couldn't find examples that suited my situation.

I have this method for returning customers. How can I use the string array of codes to filter it? Contains doesn't work for me.

public static List<Customer> GetCustomers(string[] customerCodesArray)
{
    using (busDataContext g = new busDataContext())
    {
        return g.Customers.Where(
            x => x.customerCode.Contains(customerCodesArray)).ToList();
    }
}

Try the following code:

return g.Customers.Where(x => customerCodesArray.Contains(x.customerCode)).ToList();
