make comment in csharp

In C#, the syntax for adding a single-line comment is to prefix the comment with double forward slashes (//). Here's an example:

main.cs
// This is a single-line comment in C#
39 chars
2 lines

For adding multi-line comments, you can use the /* ... */ syntax. Here's an example:

main.cs
/*
This is a multi-line comment in C#
You can span your comment on multiple lines if you need to
*/
100 chars
5 lines

It's important to add comments to your code to make it more readable and understandable for others, especially if you're working on a team project.
