所以我遇到这个问题,qrcode数据值需要是字符串类型,但我想在随机指南中添加值。我坐在一个guid的字符串上遇到了一些麻烦。这是我的代码明智:
QR码:
public void QRBarcode(string fileName)
{
BarcodeEngine engine = new BarcodeEngine();
string outputFile = @"C:\QRCodeTesting\CreatedQRCode.pdf";
int resolution = 300;
using (RasterImage image = RasterImage.Create((int)(8.5 * resolution), (int)(11.0 * resolution), 1, resolution, RasterColor.FromKnownColor(RasterKnownColor.White)))
{
//Guid guidValue = new Guid();
// Write two QR barcodes
WriteBarcode(engine.Writer, image, QRBarcodeSymbolModel.Model1AutoSize, "need to add a guid", true);
}
}
写二维码:
private void WriteBarcode(BarcodeWriter writer, RasterImage image, QRBarcodeSymbolModel symbolModel, string guidValue, bool topLeft)
{
// Create the barcode data
QRBarcodeData barcode = BarcodeData.CreateDefaultBarcodeData(BarcodeSymbology.QR) as QRBarcodeData;
barcode.SymbolModel = symbolModel;
barcode.Value = guidValue;
.......
}

一些早些时候发布了答案,但现在即使它是正确的,它也会被删除。
Guid stringGUID = Guid.NewGuid().toString();
