在 VS2019 中發行網站時出現錯誤 "指定的路徑、檔名，或是兩者都太長。完整的檔名必須少於 260 個字元，並且目錄名稱必須少於 248 個字元。", 造成發佈失敗。
解決方法:
修改環境變數 TEMP 及 TMP 為 C:\TEMP ,獲得改善。
不一定要用路徑 C:\TEMP, 但是要儘量的簡短。

由於 iTextSharp 內建的 QRCode 類別對於中文內容的支援度較差，
需經過幾道 override 的程序改寫才可存中文，所以在此直接採用
第三方元件 MessagingToolkit.QRCode。
利用此第三方元件的QRCodeEncoder物件即可產生QRCode的點陣圖Bitmap，
再將bitmap轉換成iTextSharp.text.Image即可加入到pdf之中：
QRCodeEncoder chtEncoder = new QRCodeEncoder();
//第三方先產生bitmap
Bitmap qrBitmap1 = chtEncoder.Encode("qrcode裝中文內容"); //將內容轉碼成 QR code
//再將bitmap轉換成iTextSharp.text.Image
iTextSharp.text.Image qrImage1 = iTextSharp.text.Image.GetInstance(qrBitmap1, BaseColor.BLACK);
qrImage1.ScalePercent(50);
qrImage1.Alignment = Element.ALIGN_RIGHT;//透過Image.Alignment來設定靠左靠右
pa.Add(qrImage1);
doc.Add(pa);
doc.Close();

doc.Add(pa);
doc.Close();
