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());
}
根据选择的类型生成条码
