   MailMessage^ message = gcnew MailMessage( L"jane@contoso.com",L"ben@contoso.com",L"A text message for you.",L"Message: " );
   
   // Attach the message string to this email message.
   Attachment^ data = gcnew Attachment( textMessage );
   
   // Send textMessage as part of the email body.
   message->Attachments->Add( data );
   ContentType^ content = data->ContentType;
   content->MediaType = MediaTypeNames::Text::Plain;
   
   //Send the message.
   // Include credentials if the server requires them.
   SmtpClient^ client = gcnew SmtpClient( server );
   client->Credentials = CredentialCache::DefaultNetworkCredentials;
   client->Send( message );
   data->~Attachment();
   client->~SmtpClient();
}

public static void CreateMessageInlineAttachment2(string server, string
textMessage)
{
    // Create a message and set up the recipients.
    MailMessage message = new MailMessage(
       "jane@contoso.com",
       "ben@contoso.com",
       "A text message for you.",
       "Message: ");

    // Attach the message string to this email message.
    Attachment data = new Attachment(textMessage);
    // Send textMessage as part of the email body.
    message.Attachments.Add(data);
    ContentType content = data.ContentType;
    content.MediaType = MediaTypeNames.Text.Plain;
    //Send the message.
    // Include credentials if the server requires them.
    SmtpClient client = new SmtpClient(server);
    client.Credentials = CredentialCache.DefaultNetworkCredentials;

    try
    {
        client.Send(message);
    }
    catch (Exception ex)
    {
        Console.WriteLine("Exception caught in CreateMessageInlineAttachment2: {0}",
            ex.ToString());
    }
    data.Dispose();
}

Remarks

The value of the ToString method contains the string used to create this ContentType, if one was specified and no property values have been changed. If no string was specified, or one or more property values have changed since this ContentType was created, the value of ToString is a string in the format of a Content-Type header that is composed using the current property values. The string does not include the "Content-type:" prefix.

The syntax of the Content-Type header is described in RFC 2045 Section 5.1, available at https://www.ietf.org.
