问题描述

大家好，

我无法在ASP.NET中发送SMTP邮件时发送附件.

Hi all,

Im not able to send the attachments while sending SMTP mails in ASP.NET.

using System.Web.Mail;

//在发送按钮事件中，我放置了此代码.

//In the send button event,i placed this code.

Server.ScriptTimeout = 1000;
        MailMessage msg = new MailMessage();
        msg.From = this.Txtfrom.Text;
        msg.To = this.TxtTo.Text;
        msg.Cc = this.TxtCC.Text;
        msg.Subject = this.Txtsub.Text;
        msg.Body = this.Txtbody.Text;

        if (filatchmnt1.PostedFile != null)
        {
            HttpPostedFile atchfile = filatchmnt1.PostedFile;
            int atchlen = atchfile.ContentLength;
            if (atchlen > 0)
            {
                strfilename = Path.GetFileName(filatchmnt1.PostedFile.FileName);
                filatchmnt1.PostedFile.SaveAs(Server.MapPath(strfilename));
                MailAttachment atch = new MailAttachment(Server.MapPath(strfilename));
                msg.Attachments.Add(atch);
                
            }
        }
        try
        {
            SmtpMail.Send(msg);
            MessageBox.Show("Mail has been sent to" + msg.To + '&' + msg.Cc);
          
        }
        catch (Exception ex)
        {
            MessageBox.Show("Exception:" + ex.Message);
        }
        Response.Flush();

错误名称strfilename在当前上下文中不存在；".
