This constructor initializes the Host, Credentials, and Port properties for the new SmtpClient by using the settings in the application or machine configuration files. For more information, see <mailSettings> Element (Network Settings).

The following code example demonstrates sending an e-mail message.


Public Shared Sub CreateTestMessage3()
    Dim [to] As New MailAddress("jane@contoso.com")
    Dim [from] As New MailAddress("ben@contoso.com")
    Dim message As New MailMessage([from], [to])
    message.Subject = "Using the new SMTP client."
    message.Body = "Using this new feature, you can send an e-mail message from an application very easily."
    ' Use the application or machine configuration to get the 
    ' host, port, and credentials.
    Dim client As New SmtpClient()
    Console.WriteLine("Sending an e-mail message to {0} at {1} by using the SMTP host={2}.", [to].User, [to].Host, client.Host)
    Try
        client.Send(message)
    Catch ex As Exception
        Console.WriteLine("Exception caught in CreateTestMessage3(): {0}", ex.ToString())
    End Try
End Sub
