How to pass text from textbox to report, with VS 2015, in C#?

Question

I’m creating an app for where I work, which should print some information-based labels that I enter into a form I created.

For that, I’m creating a smaller version, to test if everything I want works. I am using Visual Studio 2015 Community with files in RDLC format.

I have a form with a textbox with the name "tb_info", and a report with a parameter named "param_info". The goal is, when pressing the form button, it passes the information of the textbox for the parameter of report, giving the order to print the report next.

Some idea to accomplish this?

Following is a template of an action that would return the report in PDF format, this concept addresses the loading of the "RDLC", the bind with the "Datasource" and variable assignment, hopefully useful:

public FileResult GetRelatorio()
{
    ReportViewer report = new ReportViewer();
    report.LocalReport.DisplayName = "Relatório";

    //Carregue o rdlc do seu relatório
    using (FileStream stream = new FileStream("meu_relatorio.rdlc", FileMode.Open))
       report.LocalReport.LoadReportDefinition(stream);

    //Adicione o seu datasource
    report.LocalReport.DataSources.Add(new ReportDataSource
    {
        Name = "Nome no data source",
        Value = "Seu data source"
    });

    //Dê valor aos parâmetros do seu relatório
    ReportParameter[] parameters = new ReportParameter[]{
        new ReportParameter("Texto1", txt1.Text),
        new ReportParameter("Texto2", txt2.Text)
    };
    report.LocalReport.SetParameters(parameters);

    //Gere o seu relatório em PDF
    byte[] Arquivo = report.LocalReport.Render("PDF");
    Stream stream = new MemoryStream(Arquivo);
    return File(stream, "application/pdf");
}
