            BarcodeSettings settings = new BarcodeSettings();
            //设置条形码类型为EAN-13 
            settings.Type = BarCodeType.EAN13;
            //设置条形码数据 
            settings.Data = "12312";
            //使用校验和
            settings.UseChecksum = CheckSumMode.ForceEnable;
            //在底部显示条形码数据
            settings.ShowTextOnBottom = true;
            //设置宽度
            settings.X = 1f;
            BarCodeGenerator generator = new BarCodeGenerator(settings);

            Image image = generator.GenerateImage();
            image.Save("EAN-13.png", System.Drawing.Imaging.ImageFormat.Png);
        

 

二维码 :

    //创建BarcodeSettings对象
            BarcodeSettings settings = new BarcodeSettings();
            //设置条码类型为二维码
            settings.Type = BarCodeType.QRCode;
            //设置二维码数据
            settings.Data = textBox1.Text;
            //设置数据类型为数字
            settings.QRCodeDataMode = QRCodeDataMode.Numeric;
            //不显示文本
            settings.QRCodeECL = QRCodeECL.H;
            //设置宽度
            settings.X = 2.0f;
            BarCodeGenerator generator = new BarCodeGenerator(settings);
            Image image = generator.GenerateImage();
            image.Save("Two-1.png", System.Drawing.Imaging.ImageFormat.Png);
            //二维码名字
            string str = "Two-1.png";
            //显示二维码
            this.pictureBox1.Image = Image.FromFile(@"E:\学习资料\小实训2\练习\一维码\ee\bin\Debug\" + str );
