Is there a way to print a new-line when using ?

Question

I wanna write <Message Text="Line1\nLine2\nLine3" /> but \n seems not to be working. What should I replace \n with?

(I read in the books they said that to print @ and % we use %40 and %25, so I guess the should be a number for the new-line).

Try this: <Message Text="Line1%0aLine2%0aLine3%0a" />

CR = 0x0D or 13

LF = 0x0A or 10

What a lazy answer, why not include a full example, the answer is actually contained in OP's comment (and other answer). – MarioDS Jun 03 '16 at 12:46

Well, i *could* have done the "throw it up and see if it sticks" answer, or i could explain the values necessary to achieve what the poster wanted and let them apply it themselves. – DaveE Jun 03 '16 at 15:27

Here's a better way. Use the "Escape()" property function [1] in a trivial msbuild file like so:

<Message Text="$([MSBuild]::Escape('A\r\nB\r\nC\r\n'))" />

The 'Escape()' property function should do all the magic in terms of escaping exotic characters.

Unfortunately, this doesn't seem to work. It will just print `A\r\nB\r\nC\r\n`. `Unescape()` also doesn't work. – Sebastian Krysmanski Feb 23 '21 at 10:15

You could put the lines into an item group

<ItemGroup>
      <Lines Include="Line 1 " />
      <Lines Include="Line 2 " />
      <Lines Include="Line 3 " />
</ItemGroup>

<Message Text="%(Lines.Identity)"/>

Put the multiline message in a property (in the example below called MyMultilineMessage) and then use that property in the message text. (Works at least with MSBuild for VisualStudio 2019)

    <PropertyGroup>
      <MyMultilineMessage>

Lorum ipsum...
      </MyMultilineMessage>
    </PropertyGroup>

    <Message Importance="High" Text="$(MyMultilineMessage)"/>

This also works for Error elements as well.

Edit: Modified XML example above after comment about missing PropertyGroup.

You need to use "PropertyGroup", not "Property" – kornman00 Jun 07 '21 at 04:11
It is still wrong, sorry. Use: ` .... ` – Ste Feb 12 '22 at 17:36
You are right! Should be fixed now. Thank you for spotting this! :) – Ermingol Feb 16 '22 at 12:35
