Type of issue

Issue was in the last digit of QR Code. It was showing (. * - + and Sometimes X Y A B Z). The String is M*****7202 * is as Character.**

How to solve this type issue??

QRCodeGenerator qrGenerator = new QRCodeGenerator(); QRCodeGenerator.QRCode qrCode = qrGenerator.CreateQrCode(code, QRCodeGenerator.ECCLevel.Q); System.Web.UI.WebControls.Image imgBarCode = new System.Web.UI.WebControls.Image(); imgBarCode.Height = 950; imgBarCode.Width = 950; using (Bitmap bitMap = qrCode.GetGraphic(20)) { using (MemoryStream ms = new MemoryStream()) { bitMap.Save(ms, System.Drawing.Imaging.ImageFormat.Png); byte[] byteImage = ms.ToArray(); imgBarCode.ImageUrl = "data:image/png;base64," + Convert.ToBase64String(byteImage); } plBarCode.Controls.Add(imgBarCode);

    }

I am using the same code to generate the placard.

Using this version.

Please use the current release (1.5.1). Version 1.0 is really, really old. From where did you get it?

Besides that: can you please upload one of the broken QR code images? I like to analyze it in detail.

Tested with the current release and couldn't reproduce the error. @AshishExo please confirm, that the current release solves your problem. (You can grab the current version via Nuget: https://www.nuget.org/packages/QRCoder)

Closed issue due to lack of feedback. Feel free to re-open if the error still occurs with the latest release.
