asp.net中的无效邮件附件 [英] Invalid mail attachment in asp.net

问题描述

我正在发送带有附件的邮件.我实现了该解决方案，但是有一个错误； 无效的邮件附件".以下是我的代码.

I am sending mail with attachment. I implemented the solution, but there is one error; "Invalid mail attachment". Following is my code.

if (chkinstant .Checked)
{
   txtto.Visible = true;
   lblto.Visible = true;
   MailMessage msg = new MailMessage();
   msg.From = "[e-mail]";
   msg.To = txtto.Text;
   msg.Subject = txtsub.Text.Trim();
   msg.Body = txtbody.Text;

   HttpFileCollection hfc = Request.Files;
   for (int z = 0; z < hfc.Count; z++)
   {
       HttpPostedFile hpf = hfc[z];
       if (hpf.ContentLength > 0)
       {
           hpf.SaveAs(Server.MapPath("MyFiles") + "\\" +
             System.IO.Path.GetFileName(hpf.FileName));
           string strfilename = hpf.FileName;
           msg.Attachments.Add(new MailAttachment(strfilename));
           SmtpMail .Send(msg);
           lblmessage.Text = "Your message has been sent.";
       }
   }
   SmtpMail.Send(msg);
   lblmessage.Text = "Your message has been sent.";
}

推荐答案

我认为这与文件类型无关.我可能是权限问题.如果某个文件夹中所有文件的附件均失败，则必须对该文件夹及其上的安全设置(ASPNET应该具有读取权限)进行某些操作.

I don''t think it has something to do with the file type. I can be a permission problem. If the attachment of all files in some folder fails it should have to do something with that folder and the security settings on it (ASPNET should have read rights).

请尝试遵循

Please try following

string FileName = Server.MapPath("MyFiles") + "\\" + Path.GetFileName(hpf.FileName);
msg.Attachments.Add(new MailAttachment(FileName));
