SYSK 146: SMTP – More Configuration, Less Code

If you’re using SmtpMail class in your projects, you may want to check out a new class in .NET 2.0 -- System.Net.SmtpClient.

 

This class allows you to send messages asynchronously and to receive a notification when the e-mail has been sent.  You can also cancel any pending asynchronous e-mails.  And there is less code to write! -- Settings such as a host to use, the default ‘from’ e-mail account, etc. can be defined in your application, web site or machine configuration file instead of setting object properties in code:

 

<configuration>

  <system.net>

    <mailSettings>

      <smtp deliveryMethod="network" from="somebody@contoso.com">

        <network

          host="smtphost.contoso.com"

          port="25"

          defaultCredentials="true"

        />

      </smtp>

    </mailSettings>

  </system.net>

</configuration>

 

 

The

SmtpClient client = new SmtpClient();

constructor will initializes the Host, Credentials, and Port properties for the new SmtpClient by using the settings in the application or machine configuration files, if they are available…

  Thanks for the tip! Great to know that the underlying code will inspect the config file for you.
