// Meaning in C

#In the C# programming language, // represents a single line comment. It is used to add comments in code to provide additional information about the code and its functionality without affecting the running of the program.

Use single-line comments

The following is the syntax for using single-line comments:

<code>// 注释内容</code>

The comment content can be any text, and can provide relevant code snippets and variables , additional information or description of the method or class.

Example

<code class="c#">// 定义一个名为 message 的字符串变量
string message = "Hello, world!";

// 在控制台中输出 message
Console.WriteLine(message);</code>

In the example above, the single-line comment provides additional information about the purpose of the message variable, and the functionality of the Console.WriteLine() method.

Differences from multi-line comments

In C#, there is another comment type called multi-line comments, using the following syntax:

<code>/*
多行注释内容
*/</code>

Multi-line comments can span across multiple lines and are mainly used to add longer explanatory comments.
