读取QR码

Question

我下载Refinery.Barcodes.Reader.dll，和现在用这样的：

Imports BusinessRefinery.Barcodes.Reader 

Partial Class _Default 
    Inherits System.Web.UI.Page 

    Protected Sub btnread_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnread.Click 
     Dim barcodes As String() = BarCodeReader.scanBarCode("D://QRSAMPLE.png", BusinessRefinery.Barcodes.Reader.BarCodeType.QRCODE) 
    End Sub 
End Class 

它运行的罚款;没有错误抛出。但是，我如何看到解码过程的结果？

Answer 1

尝试在End Sub之前加myTextBox.Text = barcodes。

编辑：

看到评论后，我想你正在运行的到是scanBarCode返回一个数组，而不是字符串。检查一下，并尝试这样的：

Imports BusinessRefinery.Barcodes.Reader 

Partial Class _Default 
    Inherits System.Web.UI.Page 

    Protected Sub btnread_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnread.Click 
     Dim barcodes As String() = BarCodeReader.scanBarCode("D://QRSAMPLE.png", BusinessRefinery.Barcodes.Reader.BarCodeType.QRCODE) 
     myTextbox.Text = barcodes(0) 
    End Sub 
End Class
