我有一个已经构建了一段时间的 VB.net 应用程序。我最近在其中一个报告中添加了活动报告 6 中的条形码。
在我的机器和其他机器上一切正常，但少数几个得到与以下相关的错误：
mscorlib - 值不能为空 - 参数名称：值
代码如下：
Dim rp As New ARPTSpecialOrderCard
CType(rp.Sections("pgDetails").Controls("labelVendorPhone"), DataDynamics.ActiveReports.Label).Text = Me.LabelVendorTelephone.Text
CType(rp.Sections("pgDetails").Controls("labelID"), DataDynamics.ActiveReports.Label).Text = Me.orderid.ToString
CType(rp.Sections("pgDetails").Controls("bcID"), DataDynamics.ActiveReports.Barcode).Text = Me.orderid.ToString
rp.Run()
frmARViewer.Viewer1.Document = rp.Document
frmARViewer.ShowDialog()
异常文本：

我需要更新用户机器上的 mscorlib.dll 吗？我不确定为什么会发生此错误。
谢谢
