Question

我是编程新手。我希望能够在我上传文件时保存到我的数据库中的网站上传文件，并发送我上传到其他两方的文件的电子邮件我怎样才能实现这个目标？

这是我目前拥有的代码但我在当前上下文中不存在文件名错误？

protected void Upload(object sender, EventArgs e)
{
    string filename = Path.GetFileName(FileUpload1.PostedFile.FileName);
    string contentType = FileUpload1.PostedFile.ContentType;
    using (Stream fs = FileUpload1.PostedFile.InputStream)
    {
        using (BinaryReader br = new BinaryReader(fs))
        {
            byte[] bytes = br.ReadBytes((Int32)fs.Length);
            string constr = ConfigurationManager.ConnectionStrings["constr"].ConnectionString;
            using (SqlConnection con = new SqlConnection(constr))
            {
                string query = "insert into tblFiles values (@Name, @ContentType, @Data)";
                using (SqlCommand cmd = new SqlCommand(query))
                {
                    cmd.Connection = con;
                    cmd.Parameters.AddWithValue("@File Name", filename);
                    cmd.Parameters.AddWithValue("@ContentType", contentType);
                    cmd.Parameters.AddWithValue("@Data", bytes);
                    con.Open();
                    cmd.ExecuteNonQuery();
                    con.Close();
                }
            }
        }
    }
    Response.Redirect(Request.Url.AbsoluteUri);
}

protected void Upload_Bt1_Click(object sender, EventArgs e)
{
    MailMessage mailObj = new MailMessage(
    txtFrom.Text, txtTo.Text, txtSubject.Text, txtBody.Text);
    SmtpClient SMTPServer = new SmtpClient("127.0.0.1");
    try
    {
        SMTPServer.Send(mailObj);
    }
    catch (Exception ex)
    {
        Label1.Text = ex.ToString();
    }
}
