[C#]二維碼產生、解碼(QRCode)【支援winform、web調用】 

winform(Demo)下載：QRCode.rar 

web(Demo)下載：webQRCode.rar

【ThoughtWorks.QRCode.dll 就是類庫】

使用時需要增加:

using ThoughtWorks.QRCode.Codec;

using ThoughtWorks.QRCode.Codec.Data;

using ThoughtWorks.QRCode.Codec.Util;

示範包中的“QRCode.dll”是封裝的類庫。可以留郵箱，發給你們源碼。

主要原始碼：

1.產生二維碼

QRCodeEncoder qrCodeEncoder = new QRCodeEncoder();   String encoding = cboEncoding.Text;   if (encoding == "Byte")   {        qrCodeEncoder.QRCodeEncodeMode = QRCodeEncoder.ENCODE_MODE.BYTE;   }   else if (encoding == "AlphaNumeric")   {        qrCodeEncoder.QRCodeEncodeMode = QRCodeEncoder.ENCODE_MODE.ALPHA_NUMERIC;   }   else if (encoding == "Numeric")   {        qrCodeEncoder.QRCodeEncodeMode = QRCodeEncoder.ENCODE_MODE.NUMERIC;   }   try   {        int scale = Convert.ToInt16(txtSize.Text);        qrCodeEncoder.QRCodeScale = scale;   }   catch (Exception ex)   {        MessageBox.Show("Invalid size!");        return;   }   try   {        int version = Convert.ToInt16(cboVersion.Text);        qrCodeEncoder.QRCodeVersion = version;   }   catch (Exception ex)   {        MessageBox.Show("Invalid version !");   }      string errorCorrect = cboCorrectionLevel.Text;   if (errorCorrect == "L")        qrCodeEncoder.QRCodeErrorCorrect = QRCodeEncoder.ERROR_CORRECTION.L;   else if (errorCorrect == "M")        qrCodeEncoder.QRCodeErrorCorrect = QRCodeEncoder.ERROR_CORRECTION.M;   else if (errorCorrect == "Q")        qrCodeEncoder.QRCodeErrorCorrect = QRCodeEncoder.ERROR_CORRECTION.Q;   else if (errorCorrect == "H")        qrCodeEncoder.QRCodeErrorCorrect = QRCodeEncoder.ERROR_CORRECTION.H;    Image image;   String data = txtEncodeData.Text;   image = qrCodeEncoder.Encode(data);   pb_view.Image = image;  

2.解析二維碼

QRCodeDecoder decoder = new QRCodeDecoder();   String decodedString = decoder.decode(new QRCodeBitmapImage(new Bitmap(pb_view.Image)));   txtEncodeData.Text = decodedString;
