Text with line break

Question

I pass some product instructions for an external charge service (website). On the screen of this site, the past messages are in the "description" field, inside an element h3, which seems to have 25 spaces with flexible height.

I pass like this:

var descricao = "Codigo: " + codigoProduto + Environment.NewLine + "Nome: " + 
nome + Environment.NewLine;

try
        {
            paymentRequest.Items.Add(
             new Item(
                "BASIC " + CodID,
                 descricao,
                 1,
                 valor
             )
         );

On the screen everything appears together in the same line of that field description.

However, the intention is to have an info on each line, for example:

Código: 1234
Nome: Daniel

This way it works but appears the br on the screen.

descricao = $"Codigo: {CodID} <br/> Nome: {nome}";

Source code of the page receiving the data:

      <td>
        <h3 title="Codigo: 1983 br / Nome: Daniel">Codigo: 1983 br 
         / Nome: Daniel</h3>
            Quantidade: 1<br />
            Valor do item: R$ 6,00
        </td>

Answer 1

Another solution:

string retorno = $"<h3>Codigo: {codigoProduto} <br> Nome: {nome} <br> Valor:  {valor} </h3>";

Answer 2

You can do it like this:

var NewLineHTML = "<br>" + Environment.NewLine;

var res = $"Codigo: {codigoProduto}" + NewLineHTML +
          $"Nome: {nome}" + NewLineHTML +
          $"Valor: {valor}" ;

what would look like in html, inside the tag h3 preexisting:

<h3>
Codigo: 789<br>
Nome: CHURRASCO<br>
Valor: 12,34
</h3>

Patch (Patch): From what I’ve seen the system is taking out the < and > and so it appears br ...
Maybe you can try to hack it by doing this:

change to:

var NewLineHTML = "_br_" + Environment.NewLine;

and on the page add this script

<script>
    document.body.innerHTML = document.body.innerHTML.replace(/_br_/g, '<br>');
</script>
