vs中使用Nuget获取QRCoder

窗体中添加按钮和Iage

后台代码

public partial class MainWindow : Window    {        public MainWindow()        {            InitializeComponent();        }        private void Button_Click(object sender, RoutedEventArgs e)        {            CreateQR(100,"aaa123!ly是是是@#￥%……",System.Drawing.Color.Black,System.Drawing.Color.White,new Bitmap(@"E:\Work\ly\MES图片\1.png"));        }        private void CreateQR(int pixelsPerModule, string info, System.Drawing.Color qrColor, System.Drawing.Color qrBackgroundColor, Bitmap logo, int iconSizePercent = 15, int iconBorderWidth = 6)        {            QRCodeGenerator qrGenerator = new QRCodeGenerator();            QRCodeData qrCodeData = qrGenerator.CreateQrCode(info, QRCodeGenerator.ECCLevel.Q);            QRCode qrCode = new QRCode(qrCodeData);            Bitmap qrCodeImage = qrCode.GetGraphic(pixelsPerModule, qrColor, qrBackgroundColor, logo, iconSizePercent, iconBorderWidth, true);            IntPtr hBitmap = qrCodeImage.GetHbitmap();            ImageSource wpfBitmap = System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap(                hBitmap,                IntPtr.Zero,                Int32Rect.Empty,                BitmapSizeOptions.FromEmptyOptions());            img.Source = wpfBitmap;        }    }

QRCoder生成的是Bitmap，在WPF中需要转换为ImageSource。

运行程序

生成成功。
