LINQ querying collection objects

class Program
   {
       static void Main(string[] args)
       {
           IEnumerable<Employee> empCollection = null;

           // populate the employee collection
           // now if you want to get primary contact of each employee

           var result = from e in empCollection
                        select new
                        {
                            EmployeeName = e.Name,
                            PrimaryContact = e.Contacts.Select(c => c.IsPrimaryContact).First()
                        };
           // result will be the IEnumerable<anonymoustype>, which contains EmployeeName and the associated primary contacts
       }
   }

   public class Employee
   {
       public string Name { get; set; }

       public IEnumerable<Contact> Contacts { get; set; }
   }

   public class Contact
   {
       public int ContactID { get; set; }

       public string EmailId { get; set; }

       public string Telephone { get; set; }

       public bool IsPrimaryContact { get; set; }
   }
