Question

我创建了一个SSRS报告，其中包含一些Code128条形码。条形码使用最新的zxing.net库生成。我想在Code128条形码中包含制表符（char（9））。但它失败并出现以下异常消息：

System.ArgumentException：输入中的错误字符：

毋庸置疑，它就像没有制表人角色的魅力。

报告中使用GetBarCodeHorizontal生成条形码。但是，出于测试目的，我将其包装到visual studio vb项目中：

Class MainWindow
    Public Function GetBarCodeHorizontal(ByVal s As String, ByVal width As Integer) As Byte()
        Dim writer As New ZXing.BarcodeWriter()
        Dim ms As System.IO.MemoryStream = New System.IO.MemoryStream()

        writer.Format = ZXing.BarcodeFormat.CODE_128
        writer.Options = New ZXing.Common.EncodingOptions
        writer.Options.Width = width
        writer.Options.Height = 60
        writer.Options.PureBarcode = False
        'writer.Options.Hints.Add(ZXing.EncodeHintType.CHARACTER_SET, "UTF-8")

        Dim bmp As System.Drawing.Bitmap = writer.Write(s)

        bmp.Save(ms, System.Drawing.Imaging.ImageFormat.Png)
        Dim imagedata As Byte()
        imagedata = ms.GetBuffer()
        Return imagedata
    End Function


    Private Sub MainWindow_OnLoaded(sender As Object, e As RoutedEventArgs)
        Try
            Dim barCodeHorizontal = GetBarCodeHorizontal("3999999   80  1XXXXXX8    r1XX3", 200)
        Catch ex As Exception
            Console.WriteLine(ex)
        End Try
    End Sub
End Class

问题：

我该如何解决这个问题？
这是zxing库的限制吗？
是否有合适的解决方法（或者甚至是其他库）？

我最终得到another (free) library，结果非常好。

还有tutorial如何将条形码嵌入到此特定库的SSRS中。

对于那些感兴趣的人，我的代码是创建条形码：

 Public Function GetBarcode(ByVal text As String, ByVal barcodeWidth As Integer, ByVal barcodeHeight As Integer) As Byte()
        Dim b As System.Drawing.Bitmap
        Dim bar As New BarcodeLib.Barcode
        bar.Alignment = BarcodeLib.AlignmentPositions.CENTER

        bar.IncludeLabel = False
        b = bar.Encode(BarcodeLib.TYPE.CODE128, text, barcodeWidth, barcodeHeight)
        Dim bitmapData As Byte() = Nothing
        Using ms As New System.IO.MemoryStream()
            b.Save(ms, System.Drawing.Imaging.ImageFormat.Png)
            bitmapData = ms.ToArray()
        End Using
        Return bitmapData
    End Function

条形码数据直接来自查询，如下所示：

SELECT        MilkrunID, Code, Quantity, Batch, PickLocation, Code + CHAR(9) + CAST(Quantity AS NVARCHAR(20)) + CHAR(9) + Batch + CHAR(9) + PickLocation AS Barcode
FROM            Tbl_ReportData_ProductionReplenishment_MilkrunSummary

char（9）创建一个Tab。

如何使用zxing.net
