problem with mail attachment
<p>I'm having problem in  mail attachment.I'm using the fileupload control to get the path
of the file from the local machine.</p>

<p>It's giving the proper path but while attching the file from any folder its giving error "Invalid mail attachment".</p>

<p>Following is the code..</p>

<pre><code>  protected void sndmail_Click(object sender, EventArgs e)
    {
        objmail = new MailMessage();
        objmail.From = txt_sender.Text;
        objmail.To = txt_recipient.Text;
        objmail.Cc = txt_cc.Text;
        objmail.BodyFormat = MailFormat.Text;
        objmail.Priority = MailPriority.High;
        objmail.Subject = txt_sub.Text;
        objmail.Body = txt_body.Text;
        SmtpMail.SmtpServer = "localhost";
        SmtpMail.Send(objmail);
        Response.Write("Mail send successfully...");

    }


    protected void attch_Click(object sender, EventArgs e)
    {
        string mypath = System.IO.Path.GetFullPath(FileUpload1.FileName);
        MessageBox.Show(mypath); 
        MailAttachment attch = new MailAttachment(mypath);

        objmail.Attachments.Add(attch);
    }
</code></pre>
