This is simple code how to send email in ASP.NET 2 with Authentication. In the following tutorial, I will show you how you can authenticate smtp client when sending emails in ASP.NET 2.0.

You need to import System.Net.Mail and System.Net namespaces to test following code.

C#

string mailFrom = "FromEmailAddressHere";
string mailTo = "ToEmailAddressHere";

string subject = "ASP.NET Test Email";


string messageBody = "This email is send to you from ASP.NET";

//  Create Mail Message Object
MailMessage message = new MailMessage(mailFrom, mailTo, subject, messageBody);

// Create SmtpClient class to Send Message
SmtpClient client = new SmtpClient();

// Here you specify your smtp host address such as smtp.myserver.com
client.Host = "localhost";

// Specify that you dont want to use default credentials
client.UseDefaultCredentials = false;

// Create user credentials by using NetworkCredential class


NetworkCredential credential = new NetworkCredential();
credential.UserName = "waqas";
credential.Password = "secret";
client.Credentials = credential;
client.Send(message);

VB.NET

Dim mailFrom As String = "FromEmailAddressHere"
Dim mailTo As String = "ToEmailAddressHere"

Dim subject As String = "ASP.NET Test Email"

Dim messageBody As String = "This email is send to you from ASP.NET"

' Create Mail Message Object
Dim message As New MailMessage(mailFrom, mailTo, subject, messageBody)

' Create SmtpClient class to Send Message
Dim client As New SmtpClient()

' Here you specify your smtp host address such as smtp.myserver.com
client.Host = "localhost"

' Specify that you dont want to use default credentials
client.UseDefaultCredentials = False

' Create user credentials by using NetworkCredential class

Dim credential As New NetworkCredential()
credential.UserName = "waqas"
credential.Password = "secret"
client.Credentials = credential

client.Send(message)
