"Codabar" barcode generator by Zxing failed in Xamarin.ios

Question

I want to show QR-code and Codabar code both.

This is my code.

var qrcodeWriter = new ZXing.Mobile.BarcodeWriter {
    Format = ZXing.BarcodeFormat.QR_CODE,
    Options = new ZXing.Common.EncodingOptions {
        Width = 400,
        Height = 400,
       Margin = 1
    }
};
var qrcode = qrcodeWriter.Write (order.order_number);
imageQR.Image = qrcode;

var barcodeWriter = new ZXing.Mobile.BarcodeWriter {
    Format = ZXing.BarcodeFormat.CODABAR,
    Options = new ZXing.Common.EncodingOptions {
        Width = 400,
        Height = 80,
        Margin = 1
    }
};
var barcode = barcodeWriter.Write (order.order_number);
imageBar.Image = barcode;

QR-code success but codabar failed at barcodeWriter.write function.

Please help me.

Answer 1

I find reason.

It was format of CODABAR.

Barcodes have each different formats.

So if you make CODABAR with QRcode's format text then it crash.

Additionally, CODE_128 and QRcode's format are same.
