    new SmtpClientAttach() { Name="Attach2.txt", Stream = new MemoryStream(Encoding.ASCII.GetBytes("Content of Attach File 2")) },
    //More attach files
    //You can just use FileStream instead of MemoryStream to specify an attach file
};

SmtpClient sc = new SmtpClient(server, true); //or false if you don't want to use SSL
await sc.SendAsync(username, password, to, subject, content, true, files);
