這是我某個功能，按下修改後會出現一張表單

我想將這個表單轉成PDF檔
但目前路徑好像有問題，想請各位幫我看一下

這是登入表單後的URL

http://localhost:11477/NIS/Guide/PDPatGuideTestEdit?strGuid=98AA91FA-1187-4FA3-9C02-A5044FB3FB2A

我是參考這個網站的
https://dotblogs.com.tw/shadow/2014/02/09/143891

這是我的controller

 [HttpGet]
        public ActionResult ExportPDF(string strGuid)
        {      
            WebClient wc = new WebClient();
            string htmlText = wc.DownloadString("http://localhost:11477/NIS/Guide/PDPatGuideTestEdit?strGuid"+strGuid);
            byte[] pdfFile = this.ConvertHtmlTextToPDF(htmlText);

            return File(pdfFile, "application/pdf", "範例PDF檔.pdf");
        }

        private byte[] ConvertHtmlTextToPDF(string htmlText)
        {
            if (string.IsNullOrEmpty(htmlText))
            {
                return null;
            }
            //避免當htmlText無任何html tag標籤的純文字時，轉PDF時會掛掉，所以一律加上<p>標籤
            htmlText = "<p>" + htmlText + "</p>";

            MemoryStream outputStream = new MemoryStream();//要把PDF寫到哪個串流
            byte[] data = Encoding.UTF8.GetBytes(htmlText);//字串轉成byte[]
            MemoryStream msInput = new MemoryStream(data);
            Document doc = new Document();//要寫PDF的文件，建構子沒填的話預設直式A4
            PdfWriter writer = PdfWriter.GetInstance(doc, outputStream);
            //指定文件預設開檔時的縮放為100%
            PdfDestination pdfDest = new PdfDestination(PdfDestination.XYZ, 0, doc.PageSize.Height, 1f);
            //開啟Document文件 
            doc.Open();
            //使用XMLWorkerHelper把Html parse到PDF檔裡
            XMLWorkerHelper.GetInstance().ParseXHtml(writer, doc, msInput, null, Encoding.UTF8, new UnicodeFontFactory());
            //將pdfDest設定的資料寫到PDF檔
            PdfAction action = PdfAction.GotoLocalPage(1, pdfDest, writer);
            writer.SetOpenAction(action);
            doc.Close();
            msInput.Close();
            outputStream.Close();
            //回傳PDF檔案 
            return outputStream.ToArray();

        }

我有看一下路徑傳的值，我發現他回傳的不是我表單裡的內容
所以想請問這個路徑我該如何修改?
