Question

这是ASP.net的代码，此脚本在IIS（QR_Code.aspx）上运行

操作系统：Windows 10 PRO

<%@ Page language="vb" debug=true %>
<%@ Import NameSpace = "Zxing.Interop.Encoding.BarcodeWriter" %>
<%@ Import NameSpace = "System.IO" %>
<%@ Import NameSpace = "System.Drawing" %>

'-----------------------------------------------'
'QR-Code
'-----------------------------------------------'
Dim ZX As New ZXing.BarcodeWriter
Dim bmp As Bitmap

Zx.Format = ZXing.BarcodeFormat.QR_CODE
Zx.Options.Height = 250
Zx.Options.Width = 250
Zx.Options.Margin = 0.9
Zx.Options.PureBarcode = True
Zx.Format = 2048

bmp = Zx.Write("Test_1234")
bmp.Save("c:\inetpub\wwwroot\tester\qrcode.png", Imaging.ImageFormat.Png)
'-----------------------------------------------'

上面的代码工作正常，但是我的问题是我找不到上面代码的“错误更正”的正确参考。

我尝试了以下代码，但是没有运气！

Zx.Options.ErrorCorrection = ErrorCorrectionLevel_H

或

Zx.ErrorCorrection = ErrorCorrectionLevel_H

或

ErrorCorrection = ErrorCorrectionLevel_H

请继续从浏览器获取此错误消息

Compiler Error Message: BC30456: 'ErrorCorrection' is not a member of 'ZXing.Common.EncodingOptions'.

供您参考：

感谢您抽出宝贵的时间阅读此威胁，如果我没有以正确的格式答复，请原谅我-我仍然是新来的！

Answer 1

我真的希望您能就ErrorCorrection问题向我提出建议！

Answer 2

以下代码段应该起作用：

<%@ Page language="vb" debug=true %>
<%@ Import NameSpace = "System.Drawing" %>
<%

'-----------------------------------------------'
'QR-Code
'-----------------------------------------------'
Dim ZX As New ZXing.BarcodeWriter
Dim bmp As Bitmap
Dim options as ZXing.QrCode.QrCodeEncodingOptions

options = New ZXing.QrCode.QrCodeEncodingOptions
options.ErrorCorrection = ZXing.QrCode.Internal.ErrorCorrectionLevel.H
options.Height = 250
options.Width = 250
options.Margin = 0.9
options.PureBarcode = True

Zx.Format = ZXing.BarcodeFormat.QR_CODE
Zx.Options = options

bmp = Zx.Write("Test_1234")
bmp.Save("c:\inetpub\wwwroot\tester\qrcode.png", Imaging.ImageFormat.Png)
'-----------------------------------------------'
%>

使用ZXing的QRcode（错误纠正问题）
