[dktslnc]

Hola chicos ojala me puedan dar una mano!! soy super nuevo en esto, en realidad años que no programaba y no me acuerdo de nada. tengo el siguiente codigo y cree una clase para insertar información extraida de un formulario y todo bien pero al tirar el mensaje sale que no a registrado al usuario.

using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;

public partial class Mantenedor_Usuario : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
User oUser = new User();
DataSet oDS = new DataSet();
oDS = oUser.ListarComunas(Server.MapPath("./"));
if (oDS != null)
{
ddlComuna.DataSource = oDS.Tables[0].DefaultView;
ddlComuna.DataTextField = "comuna";
ddlComuna.DataValueField = "id_localidad";
ddlComuna.DataBind();
}

oDS = oUser.ListarSexo(Server.MapPath("./"));
if (oDS != null)
{
ddlSexo.DataSource = oDS.Tables[0].DefaultView;
ddlSexo.DataTextField = "sexo";
ddlSexo.DataValueField = "id_sexo";
ddlSexo.DataBind();
}
oDS = oUser.ListarEdad(Server.MapPath("./"));
if (oDS != null)
{
ddlEdad.DataSource = oDS.Tables[0].DefaultView;
ddlEdad.DataTextField = "id_edad";
ddlEdad.DataValueField = "id_edad";
ddlEdad.DataBind();
}

}
protected void bEnviar_Click(object sender, EventArgs e)
{
User oUser = new User();
oUser.Cod_persona = Convert.ToInt32(tRut.Text);
oUser.Dv_persona = tDigitoVerificador.Text;
oUser.Id_localidad = Convert.ToInt32(ddlComuna.SelectedValue);
oUser.Nombre = tNombres.Text;
oUser.Apellido = tApellidos.Text;
oUser.Id_sexo = Convert.ToInt32(ddlSexo.SelectedValue);
oUser.Telefono = tTelefono.Text;
oUser.Id_edad = Convert.ToInt32(ddlEdad.Text);
oUser.Direccion = tDireccion.Text;
oUser.Email = tEmail.Text;
oUser.PathBD = Server.MapPath("./");
if (oUser.InsertarUsuario() >= 1)
{
Response.Write("Ingresado");
}
else
Response.Write("No fue Ingresado");
}

}
