| Sending Email with ASP.NET |
|
Whether you are building a personal website or a business website, there will be times when you will need to send emails with asp.net within your web application. Email can be sent to an individual, a website or a group of people. Using the server side code this can be easily achieve. During the era of ASP (Active Server Pages) sending email from the web application can be quiet a challenging task. However since the arrival of ASP.NET send email was an easy task. To send email out in .NET Framework version 1.x the namespace System.Web.Mail must be use to send out email. The System.Web.Mail contains several handy classes to assist programmer to quickly send email with a few scant lines of code. Moving to .NET 2.x there is a new namespace System.Net.Mail which consist of 16 different classes assist programmer to write code to deliver emails. Out of the 16 different classes there are 2 core classes that helps programmer to quickly write code to send email.
This article will be primarily focusing on sending email with System.Net.Mail as this is the prefer method of send email over the deprecated System.Web.Mail. To send an email these it generally involves five steps:
The first step is to configure the SMTP setting in the web.config file. If you server allow anonymous login then you can omit the username and password. <configuration> <system.web>
</system.web>
<!-- Apply the smtp setting --> <system.net> <mailSettings> <smtp> <network host="TheRelayServerHostName" port="portNumber" userName="username" password="password" /> </smtp> </mailSettings> </system.net> </configuration>
Properties of the SMTP setting: Host: This is the name of the relay server, for example it could be smtp.yahoo.com. Port: the default port is 25, if the server uses a different port number then specifies the port number.Username and password: if the server setting does not allow anonymous connection then enter in the username and password to the SMTP server. For illustration purposes I have created a sample enquiry form which the website user can submit their enquiry and the form will send an email to the site administrator. Here is an example of the HTML form that the user can submit an enquiry to the site administrator. When the user click on the Submit button it will trigger the server side code and an email is sent to the site administrator.

//Create a new mail message instance MailMessage mailMsg = new MailMessage(txtEmail.Text, ToAddress);

//Send the Mail Message to the specify smtp server. smtp.Send(mailMsg); } }
