Catching and E-Mailing Exceptions

Catching and E-Mailing Exceptions

Catching and e-mailing exceptions is a technique used in ASP.NET to catch exceptions and automatically send an e-mail notification to the development team or administrators. This can be very helpful in identifying and resolving problems in a timely manner.

To catch and e-mail exceptions, you can use the Application_Error event in the Global.asax file to catch unhandled exceptions, and then use the SmtpClient class to send an e-mail message containing information about the exception.

Here’s an example of how to catch and e-mail exceptions in an ASP.NET application:

void Application_Error(object sender, EventArgs e)

{

    Exception ex = Server.GetLastError();

    // Log the exception

    // Send an email notification

    SendEmail(ex);

}

private void SendEmail(Exception ex)

{

    string emailFrom = “your_email@your_domain.com”;

    string emailTo = “admin_email@your_domain.com”;

    string subject = “Exception in ASP.NET Application”;

    StringBuilder body = new StringBuilder();

    body.Append(“Exception Details:”);

    body.Append(“<br><br>”);

    body.Append(ex.ToString());

    MailMessage message = new MailMessage(emailFrom, emailTo, subject, body.ToString());

    SmtpClient client = new SmtpClient();

    client.Send(message);

}

In this example, the Application_Error method catches any unhandled exceptions and passes them to the SendEmail method. The SendEmail method uses the MailMessage class to create an e-mail message containing information about the exception, and then uses the SmtpClient class to send the message.

Note that in order to use the SmtpClient class to send e-mail messages, you need to configure the SMTP settings in your web.config file. You can do this by adding the following section to your web.config file:

<system.net>

  <mailSettings>

    <smtp from=”your_email@your_domain.com”>

      <network host=”your_smtp_server” port=”your_smtp_port” userName=”your_smtp_username” password=”your_smtp_password” />

    </smtp>

  </mailSettings>

</system.net> By catching and e-mailing exceptions in your ASP.NET application, you can quickly identify and resolve problems before they have a chance to impact users.
