using System.Collections.Generic;
using System.Linq;
using System.Web;
public class LinqClass
{
    public string Name;
    public string contact;
    public string city;

}

using System.Xml;
using System.Xml.Linq;
using System.Linq;
using System.Data;

var sp = new[] {
          new LinqClass { Name="Murugesan",
                          contact="9769104815",
                          city="Chennai"
                        },
                        new LinqClass { Name="Pandian",
                                        city="Madurai",

                                      }
          };
        foreach (var n in sp)
        { 
            Response.Write(n.Name.ToString());
