In a previous article, we explored the process of sending multiple emails using a Gmail account in ASP.NET. Now, let's delve into the realm of YahooMail and learn how to send emails through YahooMail using C# coding in an ASP.NET application. Additionally, we'll address the common SMTP server secure connection and authentication error to ensure seamless email communication.
Setting the Stage: Overview
In this tutorial, we'll utilize two essential classes, namely the MailMessage class and the SmtpClient class, both residing in the System.Net.Mail namespace. These classes provide the necessary functionality to construct email messages and facilitate their transmission.
HTML Markup: Create an Email Sending Page
To begin, we'll set up the HTML markup for our ASP.NET page, allowing users to input the recipient's email address and the email message. The snippet below demonstrates the HTML structure for our YahooMail email sending page:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Sending-Mail-Yahoo.aspx.cs" Inherits="Mail_Sending_Mail_Yahoo" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<table>
<tr>
<th colspan="2">
Sending Mails through Yahoo...!!!
</th>
</tr>
<tr>
<td style="width:20px;">To : </td>
<td><asp:TextBox ID="txt_to_emailID" runat="server" Width="310px"></asp:TextBox></td>
</tr>
<tr>
<td colspan="2">
<asp:TextBox ID="txt_msg" runat="server" TextMode="MultiLine" Height="149px"
Width="329px"></asp:TextBox>
</td>
</tr>
<tr>
<td colspan="2"><asp:Button ID="Btn_sending_Yahoo" runat="server"
Text="Sending Mail Through Yahoo" onclick="Btn_sending_Yahoo_Click" /></td>
</tr>
</table>
</div>
</form>
</body>
</html>
C# Coding: Sending Email with Yahoo Code
Now, let's implement the C# code to handle the email sending process. This code resides in the code-behind file (Sending-Mail-Yahoo.aspx.cs). The snippet showcases the essential logic for constructing and dispatching an email through YahooMail:
protected void Btn_sending_Yahoo_Click(object sender, EventArgs e)
{
MailMessage ms = new MailMessage("Your Yahoo ID", txt_to_emailID.Text);
ms.Subject = "Testing Sending Mail through Yahoo";
ms.Body = txt_msg.Text;
ms.IsBodyHtml = true;
SmtpClient smtp = new SmtpClient("smtp.mail.yahoo.com", 587);
smtp.Credentials = new System.Net.NetworkCredential("Your Yahoo ID", "Your Yahoo Password");
smtp.EnableSsl = true;
smtp.Send(ms);
}
Next Steps: Resolving SMTPException
In the subsequent tutorial, we'll address common issues, specifically the SMTP server secure connection and authentication errors, ensuring a smooth and error-free email transmission process.
Conclusion
Mastering the art of sending emails through YahooMail in ASP.NET adds a valuable skill to your repertoire. By following these step-by-step instructions, you can seamlessly integrate email functionality into your web applications. Stay tuned for our next tutorial, where we'll tackle and resolve common SMTPException scenarios, enhancing your email communication capabilities.
