类库文件我们在文件最后面下载
【ThoughtWorks.QRCode.dll 就是类库】
使用时需要增加:
using ThoughtWorks.QRCode.Codec;using ThoughtWorks.QRCode.Codec.Data;
using ThoughtWorks.QRCode.Codec.Util;
主要源代码:
1.生成二维码
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.解析二维码
QRCodeDecoder decoder = new QRCodeDecoder();
String decodedString = decoder.decode(new QRCodeBitmapImage(new Bitmap(pb_view.Image)));
txtEncodeData.Text = decodedString;
到此这篇关于asp.net C#生成和解析二维码的实例代码就介绍到这了。生活的现实摆在面前,每个人都逃避不了,是主动地接受它还是被动地承受它?现实并不像我们想象的那么美满,那么幸福,它也有残忍的一面,人要经历生离死别,那就在于我们有多大的毅力去接受它。其实现实并不可怕,可怕的是我们不能承受现实。更多相关asp.net C#生成和解析二维码的实例代码内容请查看相关栏目,小编编辑不易,再次感谢大家的支持!
