Question

Breakpoint Info Dim txtval as byte = splitline（50）首次加载表单时工作正常

在表单上有一个按钮，用于刷新再次运行例程的位置，以便从刷新数据的txt文件中读取。

声明然后在包含标题（字符串值）的txt文件行（0）上出错。 Err =从字符串到字节的转换无效

我尝试过的事情：

将变量声明为对象接下来错误恢复错误转到

任何建议。

    Do While StrTxtScheduleStreamR1.Peek() > -1
        Dim textline As String = StrTxtScheduleStreamR1.ReadLine
        'Header Level
        Dim splitline As String() = Split(textline, vbTab)

        'Sub level

        On Error Resume Next
        Dim WIPsplitOrder As String = splitline(WIPRptOrder - 1) ' Production Order
        Dim WIPSplitOpStat As String = splitline(WIPRptOpStatus - 1) ' Operation Status (REL,CRTD)
        Dim WIPSplitWCDesc As String = splitline(WIPRptWCDesc - 1) ' Workcenter Description (KIT STATION)
        Dim WIPSplitWorkCenter As String = splitline(WIPRptWcenter - 1) ' Workcenter Number (101)
        Dim MatShtOrder As String = splitline(MatShtRptOrder - 1) ' Multilevel Production Order
        Dim MatShtSmpDelDate As String = splitline(MatShtRptDelDate - 1) 'Multilevel Delivery Dates
        Dim ConfRptOrder As String = splitline(CnfRptOrder - 1) ' Production Order Confirmation Report

        Dim WIPsplitWorksOrder As String = splitline(WIPRptWorksOrder - 1) ' Works Order - Order Book
        Dim WIPsplitEquiptDesc As String = splitline(WIPRptEquiptDesc - 1) ' Equiptment Description
        Dim WipsplitValClass As String = splitline(WipRptValClass - 1) ' Equiptment Type - Order Book
        Dim WipsplitOrdQty As String = splitline(WipRptOrdQty - 1) ' Outstanding Order Qty - Order Book
        Dim txtval1 As byte = splitline(50 ) ' Remaining Production Hours - Order Book
        Dim txtval2 As byte = splitline(51 ) - WipsplitRemCap ' All Op Calc Production Hours - Order Book
        Dim BUFD As Date = splitline(32 - 1)
        Dim WipsplitSerialNo As String ' Serial Number - Order Book
        Dim WIPsplitOpInfo As String = splitline(WIPRptOpInfo - 1) 'Production Operation Description - Order Book
