This example shows how to Send Email With Attachment In Asp.Net 2.0,3.5,4.0 C# And VB.NET Using FileUpload Control. I am saving the uploaded file into memory stream rather then saving it on server.
For sending E-mail, first of all we need to add Syatem.Net.Mail namespace in code behind of aspx page.
In my previous article i describe how to send mail using gmail in asp.net
Create the page as shown in the image above, put textbox for message and FileUpload Control for adding the file attachment.
Write following code in click event of Send button in Code behind of page
C#
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 btnSend_Click(object sender, EventArgs e)
{
MailMessage mail = new MailMessage();
mail.To.Add(txtTo.Text);
//mail.To.Add("amit_jain_online@yahoo.com");
mail.From = new MailAddress(txtFrom.Text);
mail.Subject = txtSubject.Text;
mail.Body = txtMessage.Text;
mail.IsBodyHtml = true;
//Attach file using FileUpload Control and put the file in memory stream
if (FileUpload1.HasFile)
{
mail.Attachments.Add(new Attachment(FileUpload1.PostedFile.InputStream, FileUpload1.FileName));
}
SmtpClient smtp = new SmtpClient();
smtp.Host = "smtp.gmail.com"; //Or Your SMTP Server Address
smtp.Credentials = new System.Net.NetworkCredential
("YourGmailID@gmail.com", "YourGmailPassword");
//Or your Smtp Email ID and Password
smtp.EnableSsl = true;
smtp.Send(mail);
}
}
