Examples

The following code example demonstrates sending an email message by using the SmtpClient, MailAddress, and MailMessage classes.

static void CreateCopyMessage( String^ server )
{
   MailAddress^ from = gcnew MailAddress( L"ben@contoso.com",L"Ben Miller" );
   MailAddress^ to = gcnew MailAddress( L"jane@contoso.com",L"Jane Clayton" );
   MailMessage^ message = gcnew MailMessage( from,to );
   
   // message.Subject = "Using the SmtpClient class.";
   message->Subject = L"Using the SmtpClient class.";
   message->Body = L"Using this feature, you can send an email message from an application very easily.";
   
   // Add a carbon copy recipient.
   MailAddress^ copy = gcnew MailAddress( L"Notification_List@contoso.com" );
   message->CC->Add( copy );
   SmtpClient^ client = gcnew SmtpClient( server );
   
   // Include credentials if the server requires them.
   client->Credentials = CredentialCache::DefaultNetworkCredentials;
   Console::WriteLine( L"Sending an email message to {0} by using the SMTP host {1}.", to->Address, client->Host );
   client->Send( message );
   client->~SmtpClient();
}

public static void CreateCopyMessage(string server)
{
    MailAddress from = new MailAddress("ben@contoso.com", "Ben Miller");
    MailAddress to = new MailAddress("jane@contoso.com", "Jane Clayton");
    MailMessage message = new MailMessage(from, to);
    // message.Subject = "Using the SmtpClient class.";
    message.Subject = "Using the SmtpClient class.";
    message.Body = @"Using this feature, you can send an email message from an application very easily.";
    // Add a carbon copy recipient.
    MailAddress copy = new MailAddress("Notification_List@contoso.com");
    message.CC.Add(copy);
    SmtpClient client = new SmtpClient(server);
    // Include credentials if the server requires them.
    client.Credentials = CredentialCache.DefaultNetworkCredentials;
    Console.WriteLine("Sending an email message to {0} by using the SMTP host {1}.",
         to.Address, client.Host);

    try
    {
        client.Send(message);
    }
    catch (Exception ex)
    {
        Console.WriteLine("Exception caught in CreateCopyMessage(): {0}",
            ex.ToString());
    }
}

Remarks

The MailAddress class is used by the SmtpClient and MailMessage classes to store address information for email messages.

A mail address is composed of a User name, Host name and optionally, a DisplayName. The DisplayName can contain non-ASCII characters if you encode them.

The MailAddress class supports the following mail address formats:

• A simple address format of user@host. If a DisplayName is not set, this is the mail address format generated.

• A standard quoted display name format of "display name" <user@host>. If a DisplayName is set, this is the format generated.

• Angle brackets are added around the User name and Host name, if these are not included. For example, "display name" user@host is changed to "display name" <user@host>.

• Quotes are added around the DisplayName, if these are not included. For example, display name <user@host> is changed to "display name" <user@host>.

• Unicode characters are supported in the DisplayName property.

• A User name with quotes. For example, "user name"@host.

• Consecutive and trailing dots in user names. For example, user...name..@host.

• Bracketed domain literals. For example, <user@[my domain]>.

• Comments. For example, (comment)"display name"(comment)<(comment)user(comment)@(comment)domain(comment)>(comment). Comments are removed before transmission.

A comma is used to separate elements in a list of mail addresses. As a result, a comma should not be used in unquoted display names in a list. The following mail addresses would be allowed:

"John, Doe" <user@host>, "Bob, Smith" <user2@host>

The following mail address would not be allowed:

John, Doe <user@host>, Bob, Smith <user2@host>

Quotes can be embedded in a quoted string, but they must be escaped. The following mail addresses would be allowed:

"John \"Jr\" Doe" <user@host>

"\"John \\\"Jr\\\" Doe\" <user@host>"

The following mail address would not be allowed:

"John "Jr" Doe" <user@host>

When the username is not quoted, all text between the start of the string (or comma) and the address are considered part of the DisplayName, including comments. For example:

(non comment) unquoted display (non comment) name (non comment) <user@host>

Although the MailAddress class accepts a mail address as valid, other mail servers may not accept the mail address.

The MailAddress class does not support the following mail address formats:

• Mixed quoted and unquoted display names. For example, display "name" <user@host>.

• Groups, as defined in RFC 2822 Section 3.4 published by the IETF.

• The obsolete user name formats of "user"."name"@host, user."name"@host or "user".name@host.
