导入按钮代码如下：

Dim dlg As New OpenFileDialog
dlg.Filter = "Excel文件|*.xls"
dlg.MultiSelect = True \'允许选择多个文件
If dlg.ShowDialog =DialogResult.OK Then
    Dim Book As New XLS.Book(dlg.FileName)

    Dim nms() As String = {"工作单位","县公司","姓名","性别","身份证号码","文化程度","鉴定等级","申报鉴定工种","鉴定批次","申报性质","理论成绩","实潜资格","考评分组","考核项目","考点","实操考核时间","实操考核地点","实操序号","实操成绩","潜能答辩时间","潜能序号","潜能成绩","实潜准考证号码","备注","照片"}
    For n As Integer = 1 To Sheet.Rows.Count -1
        Dim sfzhm As String = sheet(n,4).Text
        Dim dr As DataRow = DataTables("实操潜能表").Find("身份证号码 = \'" & sfzhm & "\'")
        If dr Is Nothing Then \'如果不存在同编号的订单
            dr =  DataTables("实操潜能表").AddNew()
        End If
        For m As Integer = 0 To nms.Length - 1
            If DataTables("实操潜能表").DataCols(nms(m)).IsBoolean Then
                If Sheet(n,m).Value = 0 Then

                Else
                    dr(nms(m)) = True

            End If
        Next
    Next

 提示，说明你的excel表格有错误。

For m As Integer = 0 To nms.Length - 1
    If DataTables("实操潜能表").DataCols(nms(m)).IsBoolean Then
        If Sheet(n,m).Value = 0 Then

        \'表达式列
    Else

Next

代码还是报错！搞不定了，求指教！

 汗

Else If DataTables("实操潜能表").DataCols(nms(m)).IsNumeric Then
        dr(nms(m)) = val(Sheet(n,m).Value)
