Aprenda Comentários | Introdução

In programming, comments are parts of code that are meant for leaving messages, notes or perhaps comments, in the code, for yourself or for other people who might read it. A comment does not affect the functionality of the program.

A single-line comment can be added using the double forward slash (//) operator:

main.cs


              1234567891011
            
namespace TestConsoleApp
{
    internal class Program
    {
        static void Main(string[] args)
        {   
            // This is a comment
            System.Console.WriteLine("Hello World");
        }
    }
}

A multi-line comment can be added by enclosing the text inside /* and */ operators.

main.cs


              1234567891011121314151617
            
namespace TestConsoleApp
{
    internal class Program
    {
        static void Main(string[] args)
        {   
            /*
                This
                is
                a
                multi-line
                comment
            */
            System.Console.WriteLine("Hello World");
        }
    }
}

Multi-line comments can also be used to comment out parts of a single line:

main.cs


              1234567891011
            
namespace ConsoleApp
{
    internal class Program
    {
        static void Main(string[] args)
        {
            System.Console.WriteLine(/*" This text will not be shown." */ "This text will be shown. ");
            /* System.Console.WriteLine("The whole statement is commented out"); */
        }
    }
}

It is also a common practice to comment-out a piece of code which we temporarily want to exclude from the program:

main.cs


              12345678910111213
            
namespace TestConsoleApp
{
    internal class Program
    {
        static void Main(string[] args)
        {   
            System.Console.WriteLine("Line 1");
            System.Console.WriteLine("Line 2");
            // System.Console.WriteLine("Line 3");
            System.Console.WriteLine("Line 4");
        }
    }
}

            // This is a comment
            System.Console.WriteLine("Hello World");
        }
    }

                multi-line
                comment
            */
            System.Console.WriteLine("Hello World");
        }
    }
}

    internal class Program
    {
        static void Main(string[] args)
        {
            System.Console.WriteLine(/*" This text will not be shown." */ "This text will be shown. ");
            /* System.Console.WriteLine("The whole statement is commented out"); */
        }
    }
}

            System.Console.WriteLine("Line 1");
            System.Console.WriteLine("Line 2");
            // System.Console.WriteLine("Line 3");
            System.Console.WriteLine("Line 4");
        }
    }
}
