我创建了一张VCard /名片。我需要从该Vcard创建QR码。当用户扫描然后QR码然后显示选项以将该vcard保存在联系人列表中。我能够从字符串生成QR码,但我不知道如何生成StorageFile / Vcard的QR码。
这是我的代码。
protected async override void OnNavigatedTo(NavigationEventArgs e)
{
vcard = e.Parameter as StorageFile;
IBarcodeWriter writer = new BarcodeWriter
{
Format = BarcodeFormat.QR_CODE,
Options = new ZXing.Common.EncodingOptions
{
Height = 300,
Width = 300
}
};
var result2 = vcard;
// Result2 contain vcard. but writer.Write() need string formate.
// below commented line display error. because result2 is not string
// var result = writer.Write(result2);
var result = writer.Write(result2.ToString());
var wb = result.ToBitmap() as WriteableBitmap;
//add to image component
bar_image.Source = wb;
}

请在GitHub上查看此项目:QrCoder。
根据项目的Wiki,可以为vCard和其他一些要求生成QR码。对于vCard,QrCoder仅需要大约6行代码:
-从Wiki逐字复制:
ContactData generator = new ContactData(ContactData.ContactOutputType.VCard3, "John", "Doe");
string payload = generator.ToString();
QRCodeGenerator qrGenerator = new QRCodeGenerator();
QRCodeData qrCodeData = qrGenerator.CreateQrCode(payload, QRCodeGenerator.ECCLevel.Q);
QRCode qrCode = new QRCode(qrCodeData);
var qrCodeAsBitmap = qrCode.GetGraphic(20);
