zxing.net是.net平臺下編解條形碼和二維碼的工具，使用非常方便。
本文主要說明一下多種類型條碼的生成。
適用的場景，標簽可視化設計時，自定義條碼類型，預覽。
遍歷zxing支持的全部條碼類型
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());}
根據選擇的類型生成條碼
