namespace Commandlineexample  
    class Example  
        // Main function, execution entry point of the program  
        static void Main(string[] args) 
            // Command line arguments  
            Console.WriteLine("Length of the argument: "+args.Length);  
            Console.WriteLine("Passed Arguments are:");  
            foreach (Object x in args)
