Explanation

Line 1

// A Hello World! program in C#. 

The line above is a single line comment. The characters written after ‘//’ will get converted to comments and will be ignored by the compiler.

Besides Single line comment, multiline comment is also there, which comments the block of text. To add multiline comment enclose the text in between /* and */

/* This block depicts

multiline comment

*/

Line 2

using System;

This directive references a namespace System, which is present in Microsoft .Net Framework class library. A Console class is present in this namespace, which is used in the Main method

Line 3

class Hello

This line represents the name of the class. It is recommended that it should start with Capital letter.

Line 4

{

Beginning of the class

Line 5

static void Main()

Every console application must contain a Main method. Inside the Main(), objects are created and other codes that are to be executed are placed. It is a static method.. This is the entry point of the application; the program starts execution when the main method is called.

Line 6

{

Starting of the Main() method

Line 7-8

Console.WriteLine(“Hello World!”);

Console.WriteLine(“Press any key to exit.”);

The WriteLine() method is the output method of the Console class in the run-time library. It displays the string on the output stream on a new line. If System namespace is not included in the program, System.Console.WriteLine() has to be used instead ofConsole.WriteLine().

Line9

Console.ReadKey();

It waits for any key to be pressed from the keyboard.

Line 10

            }

Closing of Main()

Line 11

}

Closing of class Hello
