Some basic linq to object query example.

Here code sample uses where clause to find all elements of an array which is less than 4.

  public void Sample1()   
   {   
     int[] num = { 8, 2, 4, 1, 5, 0, 2, 6, 7, 9 };   
     var objNum = from n in num   
                           where n < 4   
                           select n;   
     Console.WriteLine("Numbers < 4:");   
     foreach (var n in objNum)   
     {   
       Console.WriteLine(n);   
     }   
   }
