# 二维码识别生成类库ThoughtWorks.QRCode标准版

ThoughtWorks.QRCode很好用，但是该类库不支持标准库

于是我通过反编译dll，做了个标准版，并依赖引用了System.Drawing.Common

另外我发现当解析数据过长，或者QRCodeVersion>=30时，会抛出异常，

这个我做了修复，使用自动QRCodeVersion，也就是这个属性无需赋值，参考使用示例

使用示例  

```c#
using System.Drawing;
using ThoughtWorks.QRCode.Codec;
using ThoughtWorks.QRCode.Codec.Data;

namespace CommonUtils
{
    /// <summary>
    /// 二维码工具
    /// </summary>
    public static class QrCodeUtil
    {
        /// <summary>
        /// 返回二维码图片
        /// </summary>
        public static Bitmap Encode(string text)
        {
            var qrCodeEncoder = new QRCodeEncoder();
            //qrCodeEncoder.QRCodeEncodeMode = QRCodeEncoder.ENCODE_MODE.BYTE;
            //qrCodeEncoder.QRCodeScale = 4;
            //qrCodeEncoder.QRCodeVersion = 29;
            //qrCodeEncoder.QRCodeErrorCorrect = QRCodeEncoder.ERROR_CORRECTION.M;
            return qrCodeEncoder.Encode(text);
        }

        /// <summary>
        /// 定义参数,生成二维码
        /// </summary>
        public static void Create(string text, string path)
        => Encode(text).Save(path);

        /// <summary>
        /// 返回二维码定义的字符串
        /// </summary>
        public static string Decode(Bitmap image)
        {
            var qrCodeBitmapImage = new QRCodeBitmapImage(image);
            var qrCodeDecoder = new QRCodeDecoder();
            return qrCodeDecoder.decode(qrCodeBitmapImage);
        }

        /// <summary>
        /// 返回二维码定义的字符串
        /// </summary>
        public static string Decode(string path)
        => Decode(new Bitmap(path));
    }
}
```


```c#
            var path = "D:/" + DateTime.Now.ToString("yyyyMMddHHmmssfff") + ".png";
            var qr = QrCodeUtil.Encode("Hello World!");
            qr.Save(path);
            Console.WriteLine(QrCodeUtil.Decode(qr));

            path = "D:/" + DateTime.Now.ToString("yyyyMMddHHmmssfff") + ".png";
            QrCodeUtil.Create("中国智造，惠及全球！", path);
            Console.WriteLine(QrCodeUtil.Decode(path));

            Console.WriteLine("Press enter to exit...");
            Console.ReadLine();
```
