How to send Email with Attachment in Asp.net

Introduction: In this article I will explain how we can send the Email with attachment in Asp.net.

Description:

In the last article I explained How to send Email in Asp.netusing Web.config file. Add a new webform to project. After that add the below given code to .aspx page:

<table border="1px solid">

    <tr><b>Send Email with Attachment in Asp.net</b></tr>

    <tr><td>To:</td><td>

        <asp:TextBox ID="txtemail" runat="server"></asp:TextBox></td></tr>

        <tr><td>Subject:</td><td>

            <asp:TextBox ID="txtsubject" runat="server"></asp:TextBox></td></tr>

            <tr><td>Message:</td><td>

                <asp:TextBox ID="txtmessage" runat="server" TextMode="MultiLine"></asp:TextBox></td></tr>

                <tr><td>Attachment:</td><td>

                    <asp:FileUpload ID="fileupload" runat="server" /></td></tr>

                    <tr><td>&nbsp;</td><td>

                        <asp:Button ID="Button1" runat="server" Text="Send Email"

                            onclick="Button1_Click" /></td></tr>

        </table>

Now go to .aspx.cs page and write the below given code:

using System.Net.Mail;

      protected void Button1_Click(object sender, EventArgs e)

        {

            try

            {

                MailMessage message = new MailMessage();

                message.From = new MailAddress("saklanivijay87@gmail.com", "Saklani");

                message.To.Add(txtemail.Text);

                message.Subject = txtsubject.Text;

                message.Body = txtmessage.Text;

                if (fileupload.HasFile)

                {

                    message.Attachments.Add(new Attachment(fileupload.PostedFile.InputStream, fileupload.FileName));

                }

                message.IsBodyHtml = true;

                SmtpClient smtp = new SmtpClient();

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

                smtp.Port = 587;

                smtp.Credentials = new System.Net.NetworkCredential("Enter Email Id here", "Enter Password here");

                smtp.EnableSsl = true;

                smtp.Send(message);

                Clear();

            }

            catch (Exception ex)

            {

            }

        }

        public void Clear()

        {

            txtemail.Text = "";

            txtmessage.Text = "";

            txtsubject.Text = "";

        }

In VB (.aspx.vb)

Imports System.Net.Mail

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click

        Try

            Dim message As New MailMessage()

            message.From = New MailAddress("saklanivijay87@gmail.com", "Saklani")

            message.[To].Add(txtemail.Text)

            message.Subject = txtsubject.Text

            message.Body = txtmessage.Text

            If fileupload.HasFile Then

                message.Attachments.Add(New Attachment(fileupload.PostedFile.InputStream, fileupload.FileName))

            End If

            message.IsBodyHtml = True

            Dim smtp As New SmtpClient()

            smtp.Host = "smtp.gmail.com"

            smtp.Port = 587

            smtp.Credentials = New System.Net.NetworkCredential("Enter Email Id here", "Enter Password here")

            smtp.EnableSsl = True

            smtp.Send(message)

            Clear()

        Catch ex As Exception

        End Try

    End Sub

    Public Sub Clear()

        txtemail.Text = ""

        txtmessage.Text = ""

        txtsubject.Text = ""

    End Sub

Now run the project and check result.
