Block commenting VB/VB.NET code

Question

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

Answer 1

The other answers explain how to comment/uncomment automatically in VB.NET. Just for completeness, in VB6 use these toolbar buttons: . More details here.

Answer 2

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

    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

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

Answer 3

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.

Answer 4

Totally abusing compiler directives here... but:

#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.

Answer 5

Select the lines you need to comment and press keys CTRL+K+C.

If you need to uncomment use CTRL+K+U

Answer 6

install MZ-Tools and you can use CTRL+SHIFT+C to comment code blocks and CTRL+SHIFT+U to uncomment code blocks.

You can also define your own key-combinations:
