Question

I want to send a file via email using c# ASP.net (Maybe more files too, but for the moment I’m concerned about sending at least only one file)

For the moment, I do have a method that does work if you want to send an Email

public string EnviarMensaje(int intIdVendedor, string strCorreoPara, string strCorreosAdicionales, string strTema, string strMensaje, string strRuta)
    {
        string strResultado="";
        DataTable dt = ConexionBD.GetInstanciaConexionBD().GetVendedorEspecifico(intIdVendedor);
        string strCuerpo = strMensaje + "\n\n\n\nMensaje Enviado Por:\n" + dt.Rows[0]["Vendedor"] + "\n" + dt.Rows[0]["Email"] + "\n" + dt.Rows[0]["Telefono"];
        string[] strListaCorreos = strCorreosAdicionales.Split(new Char[] {' ', ','}, StringSplitOptions.RemoveEmptyEntries);

        try
        {
            MailMessage mail = new MailMessage();
            SmtpClient SmtpServer = new SmtpClient("smtpout.secureserver.net");

            mail.Subject = strTema;
            mail.Body = strCuerpo;
            mail.From = new MailAddress(strCorreoDe);
            mail.To.Add(strCorreoPara);

            foreach (string c in strListaCorreos)
            {
                mail.To.Add(c);
            }

            if (strRuta != "")
            {
                Attachment attachment;
                attachment = new Attachment(strRuta);
                mail.Attachments.Add(attachment);
            }

            SmtpServer.Port = 80;
            SmtpServer.Credentials = new System.Net.NetworkCredential(strCorreoDe, strContrasena);
            SmtpServer.EnableSsl = false;

            SmtpServer.Send(mail);
            strResultado = "Exito";
        }

        catch (Exception ex)
        {
            strResultado = ex.ToString();
        }

        return strResultado;
    }

in aspx I have

<asp:FileUpload ID="fileUploadArchivos" runat="server" />

<asp:ImageButton ID="imgBtnEnviar" runat="server" Height="60px" Width="60px" ImageUrl="~/img/iconos/email.png" CausesValidation = "True" ValidationGroup="vgpCorreo" onclick="imgBtnEnviar_Click" />

and on the cs I have

EnviarEmail objEmail = new EnviarEmail();

protected void imgBtnEnviar_Click(object sender, ImageClickEventArgs e)
{
if (fileUploadArchivos.HasFile)
{
    strArchivo = Path.GetTempFileName();\\RIGHT NOW I LEFT IT THIS WAY, BUT I NOW THAT HERE IS THE PROBLEM, I DON'T KNOW WHTAT CAN I DO HERE
}
string strResultado = objEmail.EnviarMensaje((int)Session["IdVendedor"], lblCorreoPara.Text, tbxCorreoPara.Text, tbxTema.Text, tbxMensaje.Text, strArchivo);

}

However, the problem is in a FileUpload.
I have tried many methods like, Server.MapPath, Path.GetFileName, GetDirectoryName, GetFullPath, GetPathRoot… and I’m always getting either nothing, only the filename or a completely different path (I guess is a server kind of path)..

I only for the moment want to get a file path as simple as C:\Test.txt for example…
I suppose that if I can get that exact string from the FileUpload, I’ll be able to send it… However, I can’t figure out how to make it work.

Hope you can help me
Thanks

If you need a local copy of the file uploaded kept on the server you can just do

fuFileUpload.SaveAs(MapPath(filepath));

Then your strRuta can use the file you just saved via

strRuta = Server.MapPath(filepath);

ready to pass into the new Attachment object.
