C# QR bit array decode | 易学教程

问题

I was wondering is there any libraries that can decode QR code bit array instead of image. For eaxample:

{
    {1,1,1,1,1,1,1,0,0,0,1,0,1,0,1,1,1,1,1,1,1},
    {1,0,0,0,0,0,1,0,1,0,1,0,1,0,1,0,0,0,0,0,1},
    {1,0,1,1,1,0,1,0,1,0,1,1,0,0,1,0,1,1,1,0,1},
    {1,0,1,1,1,0,1,0,0,0,0,0,1,0,1,0,1,1,1,0,1},
    {1,0,1,1,1,0,1,0,1,1,1,1,1,0,1,0,1,1,1,0,1},
    {1,0,0,0,0,0,1,0,1,1,1,0,0,0,1,0,0,0,0,0,1},
    {1,1,1,1,1,1,1,0,1,0,1,0,1,0,1,1,1,1,1,1,1},
    {0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0},
    {1,1,0,1,0,0,1,1,0,0,1,1,1,0,1,1,1,0,1,1,0},
    {1,1,1,1,1,1,0,0,1,0,0,1,0,1,0,1,0,1,1,1,1},
    {0,1,1,0,0,0,1,1,0,1,1,1,0,0,1,1,1,1,1,0,1},
    {1,0,0,1,1,0,0,0,0,0,1,0,1,1,1,1,1,0,0,1,1},
    {0,1,1,0,1,1,1,1,0,0,1,1,0,1,1,1,0,0,1,0,0},
    {0,0,0,0,0,0,0,0,1,1,0,0,0,1,1,0,1,0,1,0,0},
    {1,1,1,1,1,1,1,0,1,1,0,1,1,0,1,0,1,1,0,1,0},
    {1,0,0,0,0,0,1,0,0,1,1,0,0,0,1,0,0,0,1,1,1},
    {1,0,1,1,1,0,1,0,0,0,0,0,1,1,1,0,0,0,1,1,1},
    {1,0,1,1,1,0,1,0,1,0,0,0,0,1,1,1,0,0,0,1,1},
    {1,0,1,1,1,0,1,0,0,1,1,1,0,1,1,1,0,1,1,0,1},
    {1,0,0,0,0,0,1,0,1,0,1,1,1,0,0,1,0,1,0,0,0},
    {1,1,1,1,1,1,1,0,1,0,1,0,0,1,0,1,0,0,1,1,0}
}

Would become "Hi".

I don't need any of the image functionality.

You could use zxing to decode the bit matrix. However, you need to convert the multidimensional integer array to jagged boolean array. Just convert '1' to 'true' and '0' to 'false'. Execute the following (assuming you have referenced the correct library) to get the result.

bool[][] bData; //this should be the converted bit matrix
com.google.zxing.qrcode.decoder.Decoder dec = new com.google.zxing.qrcode.decoder.Decoder();
com.google.zxing.common.DecoderResult result = dec.decode(bData);

From the presentation of QrCode.Net, it seems that it will do what you are looking for as one of its features is:

Decoding QR code given as bit matrix
