电子邮件附件大小限制

发布于 2024-12-10 00:21:48 字数 1127 浏览 0 评论 0原文

我目前正在 C# 中使用此代码将带有附件的文件通过电子邮件发送到我的 hotmail 地址。我运行了这个，在附加 800KB 文件时效果很好，但是当我尝试附加 12MB 文件时它就不行，我把它放在 try catch 中，但没有例外，就像它刚刚跳过它一样。 hotmail 的电子邮件附件大小限制为 25MB，这会影响电子邮件代码吗？或者通过代码执行此操作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 protected]");
mail.To.Add("[email protected]");
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 protected]", "password");
SmtpServer.EnableSsl = true;
SmtpServer.Send(mail);

I am currently using this code in C# to email a file to my hotmail address with an attachment. I ran this and it worked great when attaching a 800KB file, but when I try to attach a 12MB file it just won't do it, I put it in a try catch but there were no exceptions, like it just skipped it. The email attachment size limit for hotmail is 25MB, would this affect the email code, or is there a separate limit when doing it through code? Thanks.

MailMessage mail = new MailMessage();
SmtpClient SmtpServer = new SmtpClient("smtp.live.com");
mail.From = new MailAddress("[email protected]");
mail.To.Add("[email protected]");
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 protected]", "password");
SmtpServer.EnableSsl = true;
SmtpServer.Send(mail);
