MailMessage mail = new MailMessage();
mail.From = new MailAddress("sender@example.com");
mail.To.Add("recipient@example.com");
mail.Subject = "邮件主题";
mail.Body = "邮件正文";

// 将字节数组作为附件添加到邮件中
byte[] attachmentData = GetAttachmentData(); // 获取字节数组
Attachment attachment = new Attachment(new MemoryStream(attachmentData), "attachmentFileName");
mail.Attachments.Add(attachment);

SmtpClient smtpClient = new SmtpClient();
smtpClient.Host = "smtp.example.com";
