编辑“How to Add Comments in Visual Basic”



Adding comments to your Visual Basic code is a helpful practice that can make your code more readable and understandable to other developers. Here's how to add comments in Visual Basic:

1. Single-Line Comments:
Single-line comments are created using an apostrophe (') character. To add a comment to a single line, simply place the apostrophe before the text you want to comment, like this:

```
' This is a single-line comment in Visual Basic
```

Anything after the apostrophe character is considered a comment and will be ignored by the compiler.

2. Multi-Line Comments:
To add a comment that spans multiple lines, use the following syntax:

```
' This is a
' multi-line comment
' in Visual Basic
```

You can also use the REM keyword to create multi-line comments:

```
REM This is a
REM multi-line comment
REM in Visual Basic
```

3. XML Comments:
In Visual Basic, you can also add XML comments to your code. These comments are specially formatted and can be used to generate documentation for your code. To add an XML comment, use the following syntax:

```
''' <summary>
''' This is an XML comment in Visual Basic
''' </summary>
```

Note that XML comments start with three apostrophes (''') and are enclosed in XML tags.

By adding comments to your code, you can make it easier to understand and maintain. It's a good practice to add comments as you write your code, rather than trying to remember to add them later.
