二维码生成与解析 （使用ThoughtWorks.QRCode）

QRCodeEncoder qrCodeEncoder = new QRCodeEncoder();

qrCodeEncoder.QRCodeEncodeMode = QRCodeEncoder.ENCODE_MODE.BYTE; //  support different mode

qrCodeEncoder.QRCodeScale = 1;

qrCodeEncoder.QRCodeVersion = 1.0;

qrCodeEncoder.QRCodeErrorCorrect = QRCodeEncoder.ERROR_CORRECTION.L; // support different mode

string qrCodeContent = "test";

Bitmap img = qrCodeEncoder.Encode(qrCodeContent);

string filePath = "c:\\qrcode.png" // support different image format

img.Save(filePath);

QRCodeDecoder decoder = new QRCodeDecoder();
s tring decodedString = decoder.decode(new QRCodeBitmapImage(new Bitmap("c:\\qrcode.png"))); // decodedStringshould be "test".
