在Crystal Reports Visual Studio中制作二维码,可以通过以下步骤完成:
using ZXing;
using ZXing.Common;
BarcodeWriter writer = new BarcodeWriter();
writer.Format = BarcodeFormat.QR_CODE;
writer.Options = new EncodingOptions
{
Height = 200,
Width = 200,
Margin = 0
};
Bitmap bitmap = writer.Write("Your QR Code Data");
bitmap.Save("Path to save the QR Code image");
using QRCoder;
QRCodeGenerator qrGenerator = new QRCodeGenerator();
QRCodeData qrCodeData = qrGenerator.CreateQrCode("Your QR Code Data", QRCodeGenerator.ECCLevel.Q);
QRCode qrCode = new QRCode(qrCodeData);
Bitmap qrCodeImage = qrCode.GetGraphic(20);
qrCodeImage.Save("Path to save the QR Code image");
通过以上步骤,你就可以在Crystal Reports Visual Studio中制作二维码了。记得根据你选择的二维码生成库,适当调整代码中的参数和选项。
