我目前正在使用c#中的这段代码通过电子邮件将文件与附件一起发送到我的hotmail地址。我运行这个，它在附加800KB文件时工作得很好，但是当我尝试附加12MB文件时，它就是不会这样做，我把它放在try catch中，但没有例外，就像它只是跳过它一样。hotmail的邮件附件大小限制是25MB，这是否会影响邮件代码，或者通过代码进行时是否有单独的限制?谢谢。
MailMessage mail = new MailMessage();
SmtpClient SmtpServer = new SmtpClient("smtp.live.com");
mail.From = new MailAddress("email@hotmail.co.uk");
mail.To.Add("receiving@hotmail.co.uk");
mail.Subject = "Emailed from C#";
mail.Body = "Emailed with attachment";
Attachment attachment;
attachment = new Attachment(@"C:file.txt");
mail.Attachments.Add(attachment);
SmtpServer.Port = 587;
SmtpServer.Credentials = new NetworkCredential("email@hotmail.co.uk", "password");
SmtpServer.EnableSsl = true;
SmtpServer.Send(mail);
