How to Send Emails Using ASP.NET C#?

Email Sending in ASP.NET C# Applications

This guide outlines the simple process of sending emails using ASP.NET C#.

SMTP Server Configuration

1. Retrieve the SMTP server's address and port number from your email provider's settings.
2. Instantiate an SmtpClient object, providing the server address and port as arguments.

Crafting Your Email Message

1. Create a MailMessage object. Populate it with the sender's ("From") and recipient's ("To") email addresses, the subject line, and the email body text.

Sending the Email

1. Use the Send method of the SmtpClient object, passing the prepared MailMessage object as a parameter.

Example Code

Here's a code example demonstrating email transmission using a configured SMTP server:

<code class="language-csharp">SmtpClient smtpClient = new SmtpClient(smtpServerAddress, smtpPort);
smtpClient.Credentials = new NetworkCredential("username", "password");

MailMessage mail = new MailMessage();
mail.From = new MailAddress("info@example.com");
mail.To.Add("recipient@example.com");
mail.Subject = "Test Email";
mail.Body = "Hello, world!";

smtpClient.Send(mail);</code>

Debugging Tips

If email sending fails, consider these troubleshooting steps:

• Double-check the accuracy of your SMTP server address and port.
• Ensure the sender and recipient email addresses are valid and correctly formatted.
• Verify the correctness of your network credentials (username and password).
• If your SMTP server requires it, enable SSL encryption.
