Basic sample of LINQ

Here is an sample which helps in understanding LINQ better..

In this sample we will list the items in the inventory and search for the items that are finished.

using System;
using System.Linq;

namespace ConsoleApplication1
{
  class Program
  {
      static void Main(string[] args)
      {
          Products[] ProductsList = {
                                      new Products(){ Name = "Laptop", RemainingCount = 1},
                                      new Products(){ Name = "CD", RemainingCount = 0},
                                      new Products{ Name = "DVD", RemainingCount = 0},
                                      new Products{ Name = "Cabinet", RemainingCount = 2}
                                  };

          Console.WriteLine("Total Inventory Items ::");

          var Inventory = from Product in ProductsList
                          orderby Product.Name
                          select new { Name = Product.Name, RemCount = Product.RemainingCount };

          foreach (var Item in Inventory)
              Console.WriteLine("     Inventory has {0} peice of {1}", Item.RemCount, Item.Name );

          Console.WriteLine();
          Console.WriteLine();

          Console.WriteLine("Empty Inventory Items ::");

          var EmptyInventory = from Product in ProductsList
                               orderby Product.Name
                               where Product.RemainingCount == 0
                          select new { Product.Name};

          foreach (var Item in EmptyInventory)
              Console.WriteLine("     {0}", Item.Name);

          Console.Read();
      }

      class Products
      {
          public string Name{get; set;}
          public int RemainingCount{get; set;}
      }
  }
}

Hope you got the example executed..
