SmtpMail and MailMessage : Send mails in .NET

Tools UsedVisual C# .NETNamespaceSystem.Web.UtilAssemblySystem.Web.dll

The SmtpMail class can be used to send from your C# application. Mail is by default queued on the system, ensuring that the calling program does not block network traffic. The SmtpMail class is defined in the namespace System.Web.Util. You need to call

using System.Web.Util

before you use SmtpMail. This class has only one member function Send. Send sends a mail message. The Send method is overloaded. Either a MailMessage class or four arguments can be passed to the Send message. You can call the Send method in two manners:

SmtpMail.Send(txtFrom.Text, txtTo.Text, txtSubject.Text, txtMessage.Text);

Or, if you don't want to call System.Web.Util.

System.Web.Util.Smptmail.Send(txtFrom.Text, txtTo.Text, txtSubject.Text, txtMessage.Text);

You can call the Send method in two ways.

1. By passing MailMessage as a parameter

public static void Send(MailMessage);

Here MailMessage is a class.

MailMessage mailMsg = new MailMessage();

mailMsg .From = "from@fromServer.com";

mailMsg .To = "to@toServer.com";

mailMsg .Cc = "cc@ccServer.com"";

mailMsg .Bcc = "bcc@bccServer.com";

mailMsg .Subject = "SubjectOfTheMailString";

mailMsg .Body = "BodyOfTheMailString";

SmtpMail.Send(mailMsg );

2. Direct method.

public static void Send(string from , string to, string subject, string messageText);

The MailMessage Class

The MailMessage class can be used to send mails with cc, bcc or attachments. The MailMessage constructor initializes a new instance of the MailMessage class. It doesn't take any parameters.

MailMessage mail = new MailMessage();

Each member of this class are pretty easy to understand. Say you want to send an attachment with the mail. You use Attachment member to attach the mail. Say I want to attach mcb.jpg with the mail.

mail.Attachments.Add(new MailAttachment(@"C:\mcb.jpg"));
