c# – Adding comments to your code

It is always good practice to insert comments into your code so that you (as well as others) can understand what your code is doing.


You can find all my latest posts on medium.

You can place a single line comment after a line of code, or on a line of it’s own using the “//” notation.

If you want to insert a multi-line comment, then you can begin it using /* and end the comment with */.

Here we the 2 comments types in actions

Program name: Hello World
Version: 1.0
Description: Opens up a terminal and displays "Hello World"

using System; // here we are importing the "System" namespace

// We are about to define the HelloWorld class.
class HelloWorld // This line is called the "class declaration" line
{ // curly brackets are used to structure the program, here we are indicating the start of the "HelloWorld" class.
static void Main() // This is the "method declaration" line

{ // Start of method’s code block
string message = "Hello World";
Console.WriteLine (message);
} // End of method
} // end of class
