Sending Email From your ASP.NET APPLICATION

In this post we will see how to send emails from our ASP.Net application. For this first add a webform to your asp website. Then design the Default.Aspx page as the code given below..

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <table style="height: 654px; width: 101%">
            <tr>
                <td align="center" class="style6">
                    <asp:Label ID="ComposeMail_lbl_display" runat="server" Text="Compose Mail" ForeColor="Red"
                        Font-Size="Large"></asp:Label>
                    <br />
                </td>
            </tr>
            <tr>
                <td align="center" class="style5">

                            </tr>
                        </table>
                    </asp:Panel>
                </td>
            </tr>
            <tr>
                <td>
                </td>
            </tr>
        </table>
    </div>
    </form>
</body>
</html>

The c# code in the code behind file is like this..

using System;
using System.Net;

public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }
    protected void ComposeMail_btn_SendMail_Click(object sender, EventArgs e)
    {
        try
        {
            var fromAddress = txt_From.Text.ToString();
            var toAddress = txt_To.Text.ToString();
            string subject = txt_Subject.Text.ToString();
            string body = "From: " + txt_From.Text + "\n";
            body += "Subject: " + txt_Subject.Text + "\n";
            body += "Mail: " + txt_MailBody.Text + "\n";
            var smtp = new System.Net.Mail.SmtpClient();
            {
                smtp.Host = "smtp.gmail.com";
                smtp.Port = 587;
                smtp.EnableSsl = true;
                smtp.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;

                smtp.Credentials = new NetworkCredential("<e-mail id>", "<password>");
                smtp.Timeout = 20000;
            }
            smtp.Send(fromAddress, toAddress, subject, body);
            lbl_msg.Text = "Congragulations.Mail Sent Successfully...";
        }

        catch (Exception ex)
        {
            lbl_msg.Text = ex.Message.ToString();
        }

    }

    protected void btn_clear_Click(object sender, EventArgs e)
    {
        Response.Redirect("Default.aspx");
    }
}

In the above code, you can see, we are using "smtp.gmail.com", means we are sending mail using gmail id. And change the following in the line of code:

smtp.Credentials = new NetworkCredential("<e-mail id>", "<password>");

If u want to use Yahoo mail to send mail, u have to replace "smtp.gmail.com" with "smtp.yahoo.com"

Here ,
<email> -> paste your gmail/yahoo id
<password> -> paste your gmail/yahoo password

Using this, we can send simple text mail to multiple Email-id's at a time. In the "To" text box type valid Email-Id's seperated by a comma. The webpage looks like as shown below..
