今天制造了一個C#的軟件，具體是用於生成二維碼和條形碼的，包括常用的QRCode、DataMatrix、Code128、EAN-8等等。
使用的第三方類庫是Zxing.net和DataMatrix.net；另外，程序中也用了委托。
（這兩個類庫可以在VS2015的NuGet管理器中下載）
但說明一下，其中發現PDF_417是有問題，具體問題是生成的條形碼，再解析為字符串時，前面多了“A ”，也不知道是什么原因，反正我很少用到PDF_417，就算了，但其他的編碼已經測試過是沒問題的。
效果圖：
使用非常簡單，用法是：從ListView中選擇編碼類型，然后在Content中輸入內容，點擊“Encode”則在PictureBox中生成編碼，下方的save可以保存圖片，open則是打開本地的編碼圖片，點擊“Decode”后即可自動解碼。
下面直接上代碼（第一段代碼是Helper，后面的代碼如果不感興趣可以忽略）：
