Show the result of a query inside a C # textbox Website

I have a small question about displaying a query.

On my website I want to show the result of a query.

For example: Nº of employees: [and here the total appears]

I already have the links the BD made:

protected void ligabd2()
{
    adpt1 = new tb_trabalhadorTableAdapter(); 
    tabtrab = new DataSet.tb_trabalhadorDataTable();
    adpt1.Filltrabalhador(tabtrab);
}
