C# Comments

When writing code in C#, it's important to include comments to explain what the code is doing and make it easier to understand. C# supports both single-line comments and multi-line comments. In this article, we'll explore the differences between these two types of comments and provide examples of how to use them.

Single-line Comments

Single-line comments start with a double forward slash (//) and continue to the end of the line. They are used to add short, descriptive comments to a single line of code. Here's an example of a single-line comment in C#:

1int x = 5; // assign the value 5 to the variable x

In this example, the comment explains what the code is doing, making it easier to understand for other programmers.

Multi-line Comments

Multi-line comments start with a forward slash followed by an asterisk (/*) and end with an asterisk followed by a forward slash (*/). They are used to add longer comments that span multiple lines of code. Here's an example of a multi-line comment in C#:

1/*
2This is a multi-line comment in C#.
3It can span multiple lines of code and is used
4to provide detailed descriptions of the code.
5*/
6int y = 10;

In this example, the multi-line comment provides a detailed description of the code, which can be helpful when working with complex code or code that is difficult to understand.

Differences Between Single-line and Multi-line Comments

The main difference between single-line and multi-line comments is the length of the comment. Single-line comments are typically used for short, descriptive comments on a single line of code, while multi-line comments are used for longer comments that span multiple lines of code.

Another difference is the syntax used to create the comments. Single-line comments start with a double forward slash (//), while multi-line comments start with a forward slash followed by an asterisk (/*) and end with an asterisk followed by a forward slash (*/).
