Here I will explain how to send email using gmail in asp.net or send email using gmail smtp server in asp.net using c#.
Description:
To implement this mail concept in your asp.net application first we need to add this reference to our application System.Web.Mail namespace
What is System.Net.Mail
The System.Net.Mail namespace contains classes used to send electronic mail to a Simple Mail Transfer Protocol (SMTP) server for delivery.
The System.Net.Mail namespace contains classes used to send electronic mail to a Simple Mail Transfer Protocol (SMTP) server for delivery.
How we can get this reference (System.Net.Mail)
for that we need to add System.web.dll reference to our application.
for that we need to add System.web.dll reference to our application.
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 id="Head1" runat="server">
<title>Send Mail using with gmail crendentials in 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 gmail credentials in asp.net</b>
</td>
</tr>
<tr>
<td>
Gmail Username:
</td>
<td>
<asp:TextBox ID="txtUsername" runat="server"></asp:TextBox>
</td>
</tr>
<tr>
<td>
Gmail Password:
</td>
<td>
<asp:TextBox ID="txtpwd" runat="server" TextMode="Password"></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>
|
After that add this namcespace in your codebehind
using System.Net.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 = new MailAddress(txtUsername.Text);
// Recipient e-mail address.
Msg.To.Add(txtTo.Text);
Msg.Subject = txtSubject.Text;
Msg.Body = txtBody.Text;
// your remote SMTP server IP.
SmtpClient smtp = new SmtpClient();
smtp.Host = "smtp.gmail.com";
smtp.Port = 587;
smtp.Credentials=new System.Net.NetworkCredential(txtUsername.Text,txtpwd.Text);
smtp.EnableSsl = true;
smtp.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);
}
}
|
Here we used smtp.Port=587 this is the port number which is used by gmail that’s why we used this port number. In some situations if you get any error regarding security remove smtp.EnableSsl = true;
