zxing .net 多种条码格式的生成

下载地址：http://zxingnet.codeplex.com/

zxing.net是.net平台下编解条形码和二维码的工具，使用非常方便。

本文主要说明一下多种类型条码的生成。

适用的场景，标签可视化设计时，自定义条码类型，预览。

遍历zxing支持的全部条码类型

if (rb == rb1wm)
            {
                foreach (BarcodeFormat format in Enum.GetValues(typeof(BarcodeFormat)))
                {
                    if (format != BarcodeFormat.All_1D)
                        cbxBarcodeFormat.Items.Add(format.ToString());
                }
                cbxBarcodeFormat.Items.Remove(BarcodeFormat.QR_CODE.ToString());
                cbxBarcodeFormat.Items.Remove(BarcodeFormat.AZTEC.ToString());
                cbxBarcodeFormat.Items.Remove(BarcodeFormat.DATA_MATRIX.ToString());
                cbxBarcodeFormat.Items.Remove(BarcodeFormat.PDF_417.ToString());
            }
            if (rb == rb2wm)
            {
                cbxBarcodeFormat.Items.Add(BarcodeFormat.QR_CODE.ToString());
                cbxBarcodeFormat.Items.Add(BarcodeFormat.AZTEC.ToString());
                cbxBarcodeFormat.Items.Add(BarcodeFormat.DATA_MATRIX.ToString());
                cbxBarcodeFormat.Items.Add(BarcodeFormat.PDF_417.ToString());
            }
