 LINQ to Objects

LINQ to object supports the native query language in .Net with intellisense. Query Operators like select, where, join, etc. can be used against any .NET collection. LINQ integrate the use of Lambda expressions. It also uses the deferred query execution feature, where the query will be executed at the time of referring the result.

namespace ConsoleApplication{    class Program
        static void Main(string[] args)
          string[] names = { "John", "George", "Anitha", "Hari", "Vishnu", "Gauri" };
            Func<string, bool> filter = s => s.Length == 5;
            Func<string, string> extract = s => s;
            Func<string, string> project = s => s.ToUpper();

            IEnumerable<string> expr = names

            foreach (string item in expr)
