using System.Linq;
using System.Text;
namespace LINQ
{
class Program
{
static void Main(string[] args)
{
DataClassesDataContext dc = new DataClassesDataContext();

EmpDetail empQuery = (from emp in dc.EmpDetails
                      where emp.Dept == "MOSS"
                      select emp).First();
Console.WriteLine("ID :{0}, Name :{1}, Location :{2}, Department :{3}", empQuery.ID, empQuery.Name, empQuery.Location, empQuery.Dept);
Console.ReadLine();

DataClassesDataContext dc = new DataClassesDataContext();
EmpDetail empQuery = dc.EmpDetails.First();
Console.WriteLine("ID :{0}, Name :{1}, Location :{2}, Department :{3}", empQuery.ID, empQuery.Name, empQuery.Location, empQuery.Dept);
Console.ReadLine();
