Understanding and Using Comments in C#: Enhancing Code Readability and Maintainability

Learn how to effectively use comments in your C# code to improve readability and maintainability. This tutorial explains single-line and multi-line comments, demonstrates their usage, and emphasizes their importance in creating clean, well-documented, and collaborative code.

Understanding Comments in C#

Comments in C# are explanatory notes within your code that are ignored by the compiler. They're essential for making your code more understandable, maintainable, and easier to collaborate on. Comments improve code readability and help others (and your future self) understand your code's purpose and logic.

Types of Comments in C#

C# supports two main types of comments:

  1. Single-line comments
  2. Multi-line comments

Single-Line Comments

Single-line comments begin with `//` (two forward slashes). Everything on that line after `//` is treated as a comment.


int x = 10; // This is a single-line comment

Multi-Line Comments

Multi-line comments are used to comment out multiple lines of code. They start with `/*` and end with `*/`.


/* This is a 
multi-line comment.
It can span multiple lines. */
