       private void btnSend_Click(object sender, EventArgs e)
        {
            MailMessage msg = new MailMessage();
            msg.Body = this.txtBody.Text;
            msg.Subject = this.txtSubject.Text;

            msg.From = new MailAddress("邮箱详细账号");
            msg.To.Add(this.txtMailAddress.Text);
            msg.IsBodyHtml = true;

            SmtpClient client = new SmtpClient();
            client.Host = "smtp.qq.com";
            client.Port = 25;

            NetworkCredential credetial = new NetworkCredential();
            credetial.UserName = "@之前的部分";
            credetial.Password = "邮箱密码";
            client.Credentials = credetial;
            Attachment att = new Attachment(this.txtFuJian.Text);
            msg.Attachments.Add(att);
            client.Send(msg);
            MessageBox.Show("邮件发送成功");
        }

            {
                this.txtFuJian.Text = this.openFileDialog1.FileName;
