I Have submitted some Programs to understand C#

STEP 1

   // A simple program to explain the structure of a C# program
    class Program
    {
        static void Main(string[] args)
        {
            System.Console.WriteLine(" FIRST STEP FOR A C# PROGRAM");
            Console.ReadLine();
        }
    }

* This is purely Object Oriented approach so everything must me contained in a class.
* Like the header files, here we have namespaces. Here System is a namespace and Console is a class  
   contained in that namespace. Writeline is function to display the output.
* We dont have function like getch() to make the cursor wait at the output screen. Instead of that we can  
   give the statement  Console.ReadLine();
* Again ReadLine() is a function in console class.
