I'm having difficulty displaying information that comes from an object to show on a Label, returning it as a list.

//Pegando os dados do Rest e armazenando na variável usuários

var usuario = response.Content.ReadAsAsync<IEnumerable<ConsumeRoot>>().Result;

foreach (var a in usuario)
{
    lblTitulo.Text = a.titulo;
}

The label returns only one information, this class is receiving an API that is receiving information from a database, it is 6 information that is to appear on that stack inform.

c# asp.net foreach label

It turns out that the value of the label is being replaced with each loop.

Concatenate the values or use string.Join and make only one assignment

var usuario = response.Content.ReadAsAsync<IEnumerable<ConsumeRoot>>().Result;

lblTitulo.Text = string.Join(", ", usuario.Select(u => u.Titulo));

At each iteration of this foreach, you are replacing the previous information, perhaps you are forgetting to concatenate the results:

    foreach (var a in usuario)
    {
        lblTitulo.Text += a.titulo + " ";
    }
