Question

我设计了一个包含html页面作为邮件正文的邮件程序。 html页面中有某些链接。可以有任意数量的链接，我不知道它们。因为html页面中的所有内容均视为字符串。我想要的是每当我单击特定链接时，都应将该链接替换为指向中间页面的链接，在该页面中我希望通过查询字符串获取参数值。这是我的代码-

protected void btnSubmit_Click(object sender, EventArgs e)
        {
            {
                SendHTMLMail();
            }


            void SendHTMLMail()
            {
                StreamReader reader = new StreamReader(Server.MapPath("~/index1.html"));
                string readFile = reader.ReadToEnd();
                string myString = "http";
                myString = readFile;
                myString = myString.Replace(@"??", @"http://localhost:60488/url.aspx?" + "sender=" + Server.UrlEncode(this.txtUsername.Text) + "&reciever=" + Server.UrlEncode(this.txtTo.Text));


                MailMessage Msg = new MailMessage();

                Msg.From = new MailAddress(txtUsername.Text);

                Msg.To.Add(txtTo.Text);
                Msg.Subject = txtSubject.Text;
                Msg.Body = myString.ToString();
                Msg.IsBodyHtml = true;

                if (fuAttachment.HasFile)
                {
                    string FileName = Path.GetFileName(fuAttachment.PostedFile.FileName);

                    Msg.Attachments.Add(new Attachment(fuAttachment.PostedFile.InputStream, FileName));
                }

                SmtpClient smtp = new SmtpClient();
                smtp.Host = "smtp.gmail.com";
                smtp.Port = 587;
                smtp.UseDefaultCredentials = false;
                smtp.Credentials = new System.Net.NetworkCredential(txtUsername.Text, txtpwd.Text);
                smtp.EnableSsl = true;
                smtp.Send(Msg);
                Msg = null;
                ClientScript.RegisterStartupScript(GetType(), "alert", "alert('Email sent.');", true);
            }

        }

在此区块中-

StreamReader reader = new StreamReader(Server.MapPath("~/index1.html"));
                    string readFile = reader.ReadToEnd();
                    string myString = "http";
                    myString = readFile;
                    myString = myString.Replace(@"??", @"http://localhost:60488/url.aspx?" + "sender=" + Server.UrlEncode(this.txtUsername.Text) + "&reciever=" + Server.UrlEncode(this.txtTo.Text));

我尝试过的方法被认为是字符串形式的url，并赋予其初始值“ http”。由于http之后我什么都不知道，因为它可以是任何链接，例如-http://example.co.in或https://example.com 我想用中间页的链接替换该链接，也想知道http后的完整链接，并在查询字符串中发送该链接名称
