C# Comments
In this chapter you will learn C# Comments. Globaltuts.com uses a simple lesson flow: explain the idea, show a working example, then highlight what to practice next.
This chapter is part of a longer track. Take your time, run every example locally, and use the Next link at the bottom when you are ready to continue.
What you will learn
- Define C# Comments in plain language and know when to use it
- See how C# Comments fits into .NET apps, services, and desktop tools
- Study a complete example with expected output
- Avoid common beginner mistakes called out in this lesson
- Complete the practice checklist before moving to the next chapter
Before you start
Use the .NET SDK or Visual Studio to build and run a small console project.
You do not need to memorize everything on the first pass. Focus on running the example and noticing how it fits into the bigger picture of .NET apps, services, and desktop tools.
Common mistakes to avoid
- Changing many lines at once so you cannot tell which change fixed or broke the output.
- Memorizing syntax without knowing when to use C# Comments in a real project.
- Deploying tutorial snippets to production without validation, authentication, or security review.
- Using outdated syntax from an old blog post instead of the track you are following on this site.
Practice checklist
- Read the introduction once without typing, then read it again while following along.
- Run the example exactly as shown and confirm the output matches the preview.
- Change one variable or attribute and predict the result before refreshing.
- Write a two-sentence summary of C# Comments in your own words in a notes file.
Introduction
C# Comments is used when you work with .NET apps, services, and desktop tools.
If you are new, do not rush. Re-read this section, then type the example manually instead of copy-pasting blindly.
Keep official docs open in another tab; matching names to the manual beats memorizing syntax.
Concept in depth
When you see C# Comments in documentation or on the job, it usually solves a specific problem: keeping .NET apps, services, and desktop tools predictable, maintainable, and easy for others to read.
Compare the example below with the previous chapter in this track. Notice what changed and ask yourself why the author structured it that way.
Example
The sample below is intentionally small so you can see the core idea. Extend it only after you understand each line.
Match your output to the preview under the code block. If something differs, check typos, file paths, and whether you saved the file.
// Single-line
/* Block */
Console.WriteLine("Hi");Below is how the output typically looks in a browser, terminal, or API client:
Hi
Explanation
Open the previous lesson in this track and note what changed between the two examples.
Write a short note in your own words after each example so you remember why each line matters when you come back to this topic later.

Summary
You should now recognize when to use C# Comments in a project. Use the Previous and Next buttons at the bottom of this white content area to continue the course in order.
Revisit this page when you build a real feature—tutorial chapters make more sense the second time.
Key takeaways
- C# Comments is a core idea when working with .NET apps, services, and desktop tools.
- Small, runnable examples beat long theory—experiment after each lesson.
- Use the sidebar and search to revisit this chapter whenever you build something similar.
