{
    private string strcustomername = "";
    private string strcustomercode = "";
    private string strcity = "";
    public string CustomerName
    {
        set
        {

            strcustomername=value;
        }
        get
        {
            return strcustomername;
        }

    }

  public string CustomerCode
    {
        set
        {

            strcustomercode=value;
        }
        get
        {
            return strcustomercode;
        }
    }
    public string City
    {
        set
        {

            strcity=value;
        }
        get
        {
            return strcity;
        }

    }
    public clsOrder[] Orders = null;
}
class clsOrder
{
    private string strProductname;
    public string ProductName
    {
        set
        {

            strProductname=value;
        }
        get
        {
            return strProductname;
        }
    }
}
class clsLINQ
{
      clsCustomer[] objcustomer=new clsCustomer[]
     {
         new clsCustomer(CustomerName="Khadak",CustomerCode="001",City="Ludhiana",
             Orders=new clsOrder[]
             (new clsOrder(ProductName="Shirt"),
              new clsOrder(ProductName="Socks"))),
          new clsCustomer(CustomerName="DEV",CustomerCode="002",City="Ludhiana",
                 Orders=new clsOrder[]
