Send email with attachment in ASP.NET?

First, you will need to import the System.Net.Mail namespace.


using System;
using System.Data;
using System.Configuration;
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;
using System.Net.Mail;

public partial class _Default : System.Web.UI.Page
{

protected void Page_Load(object sender, EventArgs e)
{

}

protected void btnSubmit_Click(object sender, EventArgs e)
{

try
{

MailAddress SendFrom = new MailAddress(txtFrom.Text);
MailAddress SendTo = new MailAddress(txtTo.Text);

MailMessage MyMessage = new MailMessage(SendFrom, SendTo);

MyMessage.Subject = txtSubject.Text;
MyMessage.Body = txtBody.Text;

Attachment attachFile = new Attachment(txtAttachmentPath.Text);
MyMessage.Attachments.Add(attachFile);

SmtpClient emailClient = new SmtpClient(txtSMTPServer.Text);
emailClient.Send(MyMessage);

litStatus.Text = "Message Sent";

}
catch (Exception ex)
{

litStatus.Text=ex.ToString();

}

}

}
