我正在使用 Neodynamic SDK 将文档打印到客户端。

我们将有 5 个文件要打印。我了解如何打印 1 个文档或打印所有文档，但有没有办法为每个按钮打印 1 个文档。即 button1 打印出 doc1，button2 打印出 doc2，以此类推。

这是我到目前为止所得到的

  <script runat="server">

        Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs)
            fileone()
            filetwo()

        End Sub

        Public Sub fileone()
            Dim fileToPrint As New PrintFile(Context.Server.MapPath("~/forms/xmlheader.txt"), "xmlheader.txt")
            If (WebClientPrint.ProcessPrintJob(Request)) Then

                'Create a ClientPrintJob
                Dim cpj As New ClientPrintJob()
                'set client printer, for multiple files use DefaultPrinter...
                cpj.ClientPrinter = New DefaultPrinter()
                'set files-printers group by using special formatting!!!
                'Invoice.doc PRINT TO Printer1
                cpj.PrintFile = fileToPrint
                'send it...
                cpj.SendToClient(Response)
            End If
        End Sub
        Public Sub filetwo()
            Dim fileToPrint As New PrintFile(Context.Server.MapPath("~/forms/ How To Recover Office Doc.pdf"), " How To Recover Office Doc.pdf")
            If (WebClientPrint.ProcessPrintJob(Request)) Then

                'Create a ClientPrintJob
                Dim cpj As New ClientPrintJob()
                'set client printer, for multiple files use DefaultPrinter...
                cpj.ClientPrinter = New DefaultPrinter()
                'set files-printers group by using special formatting!!!
                'Invoice.doc PRINT TO Printer1
                cpj.PrintFile = fileToPrint
                'send it...
                cpj.SendToClient(Response)
            End If
        End Sub



        Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs)
            fileone()
            ScriptManager.RegisterStartupScript(Me, Me.GetType(), "printForm1", "printForm1();", True)
        End Sub

        Protected Sub Button2_Click(ByVal sender As Object, ByVal e As System.EventArgs)
            filetwo()
            ScriptManager.RegisterStartupScript(Me, Me.GetType(), "printForm2", "printForm2();", True)
        End Sub

您需要创建一个名为 PrintDoc() 的函数，该函数接收要打印的文件路径作为参数。签名应如下所示：

Private Sub PrintDoc(path as String)

End Sub

你只需要这个函数一次，不需要 sub fileone() 和 sub filetwo() ... 直到 filefive()。您只需要一个名为 PrintDoc(path as String) 的子

然后您需要 5 个按钮，每个按钮都有自己的 _Click() 事件，并且在该事件处理程序中，您通过每次传递不同的参数来调用 PrintDoc 过程。

希望这可以帮助。

祝你好运！
