How to Send Emails with Attachments

There are 4 steps to send an email with attachments.

Step 1

Step 2

Step 3

Take 3 text boxes and change the ID as TextBox_name, TextBox_email, TextBox_sub, TextBox_body and 1 fileupload control, 1 button, 1 label for message and thereafter take 4 RequiredFieldValidators and validate it with the respective text boxes and fileupload controls.

Now double click on button. It will generate click event automatically.

After this write this code on the Default.aspx.cs

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

using System.Net;

using System.Net.Mail;

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

{

protected void Page_Load(object sender, EventArgs e)

{

}

protected void Button1_Click(object sender, EventArgs e)

{

try

{

//===============================================//

MailMessage mail = new MailMessage();

mail.To.Add(TextBox_email.Text);

mail.From = new MailAddress("[email protected]");

mail.Subject = TextBox_sub.Text;

mail.Body = TextBox_body.Text;

mail.IsBodyHtml = true;

Attachment file = new Attachment(FileUpload1.PostedFile.InputStream, FileUpload1.FileName);

mail.Attachments.Add(file);

SmtpClient smtp = new SmtpClient();

smtp.Host = "smtp.gmail.com";

smtp.Port = 587;

smtp.EnableSsl = true;

smtp.Credentials = new System.Net.NetworkCredential("youremail", "yourpassword");

smtp.Send(mail);

Label6.Text = "Email to " + TextBox_email.Text + " has been send successfully";

//======================================================//

}

catch(Exception ex)

{

Label6.Text = ex.Message;

}

Or you can write this code on click event of button
