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 applicationSystem.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.nettitle>
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.netb>
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", "");
}
catch (Exception ex)
{
Console.WriteLine("{0} Exception caught.", ex);
}
}

Here use your SMTP server address then only it will work for you and check mails in spam also because sometimes mails should be appear in spam folder also.
