How to comment multiple lines of code/block of code in VB?

如何在 VB 中注释多行代码/代码块？

回答by Mehrdad Afshari

VB doesn't have such a construct at the language level. It has single line comments using apostrophe character:

VB 在语言级别没有这样的结构。它有使用撇号字符的单行注释：

' hello world
' this is a comment
Rem this is also a comment

However, Visual Studio has a functionality to automate this task. Select the lines you want and press Ctrl+K+Cfor commenting and Ctrl+K+Ufor uncommenting (General Development Settings shortcuts, look at the "Edit ->Advanced" menu while selecting some code to see the shortcuts).

但是，Visual Studio 具有自动执行此任务的功能。选择您想要的线，然后按Ctrl+ K+C的注释和Ctrl+ K+U的反注释（常规开发设置快捷键，看看“编辑->高级”菜单，同时选择一些代码来看看快捷方式）。

Totally abusing compiler directives here... but:

在这里完全滥用编译器指令......但是：

#If False Then
Comments
go
here
#End If

You don't get the benefits of proper code coloration (it doesn't show in green when using the default color scheme) and the implicit line-continuation system automatically indents lines in a paragraph starting at the second line. But the compiler will ignore the text.

您无法获得正确代码着色的好处（使用默认配色方案时它不会显示为绿色），并且隐式续行系统会自动缩进段落中从第二行开始的行。但是编译器会忽略文本。

Here is a cludgy way to make a multiline comment which is also collapsible.

这是一种制作多行注释的笨拙方法，该注释也是可折叠的。

    If <![CDATA[ Multiline comment about this and that

Comment about this 
and that and so on
with lots of lines

    ]]> Is Nothing Then : End If

It looks like this when you collapse it

当你折叠它时它看起来像这样

If <![CDATA[ Multiline comment about this and that ...  Is Nothing Then : End If

Ways you can comment code in VB:

在 VB 中注释代码的方法：

1. by using CTRL+K+C
2. adding '(Apostrophes symbol) in front of your code which you want to make it as comment
3. adding remin front of your code which you want to make it as comment. (Note:remmeans remarks --> remis used to include explanatory remarks in the source code of a program.)
4. just select the particular code and click on the option called "comment out the selected lines"in the toolbar.
5. #if false(enter your code here) #endif-- the code inside these 2 statements will be commented.

1. 通过使用CTRL+ K+C
2. 在您想要将其作为注释的代码前添加 '（撇号符号）
3. rem在您想要将其作为注释的代码前面添加。 （注：rem表示注释 -->rem用于在程序的源代码中包含解释性注释。）
4. 只需选择特定的代码，然后单击 工具栏中名为“注释掉所选行”的选项。
5. #if false（在此处输入您的代码）#endif——这两个语句中的代码将被注释。

回答by Jared

To comment out a big section of code you highlight the code you want to comment out, then you hit ctrl+K, then hit ctrl+C. To un-comment a block of commented code you hit ctrl+K, then hit ctrl+U.

要注释掉一大段代码，请突出显示要注释掉的代码，然后点击ctrl+ K，然后点击ctrl+ C。要取消注释一块已注释的代码，请点击ctrl+ K，然后点击ctrl+ U。

in VS2010 VB.NET, type 3 times ' above a class/function/property/declaration

在 VS2010 VB.NET 中，在类/函数/属性/声明上方键入 3 次 '

then it will auto generate a comment block :

然后它会自动生成一个评论块：

''' <summary>
''' GRP Business partner ID
''' </summary>
''' <value></value>
''' <returns></returns>
''' <remarks></remarks>

same thing in C# but type 3 times /

在 C# 中同样的事情，但键入 3 次 /

/// <summary>
/// 
/// </summary>
