Comment (C#)

Single Line Comment#

A single line comment starts with // and continues until the end of the line.

// Everything on this line is commented.
Console.WriteLine("Hello, World!");

You can also write it inline, to the right of your code:

Console.WriteLine("Hello, World!"); // Everything to the right is commented.

A block comment starts with /* and ends with */. Everything in between is ignored.

/*
This is a block comment
It can span
multiple lines
*/
Console.WriteLine("Hello, World!");

You can also use block comments in a single line or inline:

/* Block comment in a single line */
Console.WriteLine("Hello, World!"); /* Block comment inline */

Always close a block comment. If you don’t, everything after it will be treated as part of the comment.
