使用 XMLSerializer 直接流式传输到 MailMessage 附件中

Question

我正在使用 XMLSerializer，我需要将其直接写入邮件消息附件，最好不要先将其保存到文件中。

我的代码

var smtp = new System.Net.Mail.SmtpClient("smtp.gmail.com", 587)
        {
            Credentials = new System.Net.NetworkCredential("email@gmail.com", "password"),
            EnableSsl = true
        };

        System.IO.MemoryStream ms = new System.IO.MemoryStream();

        System.Xml.Serialization.XmlSerializer ser = new System.Xml.Serialization.XmlSerializer(typeof(XmlRoot));

        ser.Serialize(ms, model);

        var attachment = new System.Net.Mail.Attachment(ms, "file.xml", "application/xml");

        System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage();

        message.To.Add("tothisemail@gmail.com");
        message.Subject = String.Format("{0}", some subject name);
        message.From = new System.Net.Mail.MailAddress("email@gmail.com");
        message.Body = "empty content";
        message.Attachments.Add(attachment);

        smtp.Send(message);

发生的事情是电子邮件已成功发送，但它写入的 xml 文件完全是空的。

Answer 1

ser.Serialize(ms, model);

ms.Position = 0;

var attachment = new System.Net.Mail.Attachment(ms, "file.xml", "application/xml");

Writing to then reading from a MemoryStream
