In this article I will explain how to send email using asp.net.
Description:
In realtime we will use gmail,yahoo,hotmail etc to send mails to particular user here I will show to how to implement mail sending concept in asp.net.
To implement mail concept in asp.net first we need to add following reference to our application System.Web.Mail namespace
What is System.Web.Mail
System.Web.Mail is a namespace which contains classes that enable us to construct and send messages using the CDOSYS (Collaboration Data Objects for Windows 2000) message component. The mail message is delivered either through the SMTP mail service built into Microsoft Windows 2000 or through an arbitrary SMTP server.

How we can get this reference (System.Web.Mail)
We need to add System.web.dll reference to our application for that follow below steps
a
a) On the Project
menu, click Add Reference.
b)
On the .NET tab, locate System.Web.dll, and
then click Select.
c)
Click OK in the Add References.
After that design your aspx page like this:
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Send Mail using asp.net</title>
</head>
<body>
<form id="form1"
runat="server">
<div>
<table style="
border:1px solid" align="center">
<tr>
<td colspan="2"
align="center">
<b>Send Mail using asp.net</b>
</td>
</tr>
<tr>
<td>
From:
</td>
<td>
<asp:TextBox ID="txtFrom"
runat="server"></asp:TextBox>
</td>
</tr>
<tr>
<td>
Subject:
</td>
<td>
<asp:TextBox ID="txtSubject"
runat="server"></asp:TextBox>
</td>
</tr>
<tr>
<td>
To:
</td>
<td>
<asp:TextBox ID="txtTo" runat="server"></asp:TextBox>
</td>
</tr>
<tr>
<td valign="top">
Body:
</td>
<td>
<asp:TextBox ID="txtBody"
runat="server"
TextMode="MultiLine"
Columns="30"
Rows="10"
></asp:TextBox>
</td>
</tr>
<tr>
<td>
</td>
<td>
<asp:Button ID="btnSubmit"
Text="Send"
runat="server"
onclick="btnSubmit_Click"
/>
</td>
</tr>
</table>
</div>
</form>
</body>
</html>
Now add following
namcespaces in your codebehind
using System.Web.Mail;
After that write
the following code in button click
protected void btnSubmit_Click(object
sender, EventArgs e)
{
try
{
MailMessage Msg = new MailMessage();
// Sender e-mail address.
Msg.From = txtFrom.Text;
// Recipient e-mail address.
Msg.To = txtTo.Text;
Msg.Subject = txtSubject.Text;
Msg.Body = txtBody.Text;
// your remote SMTP server IP.
SmtpMail.SmtpServer = "10.20.72.1";
SmtpMail.Send(Msg);
Msg = null;
Page.RegisterStartupScript("UserMsg",
"<script>alert('Mail sent thank
you...');if(alert){ window.location='SendMail.aspx';}</script>");
}
catch (Exception ex)
{
Console.WriteLine("{0} Exception caught.", ex);
}
}
OUTPUT:
