主题：代码问题求教版主？

Dim Result As DialogResult
Result = MessageBox.Show("确定导出?", "提示", MessageBoxButtons.YesNo, MessageBoxIcon.Question,MessageBoxDefaultButton.Button2)
If result = DialogResult.Yes Then
    Dim Cols1() As String = {"工作单位","县公司","姓名","性别","身份证号码","文化程度","现岗位名称","参加工作时间","现工种工作时间","原技术资格等级","原等级取得时间","原资格证书工种","原资格证书编号","鉴定等级","申报鉴定工种","鉴定批次","申报性质","用工性质","原人才当量值","备注","照片","是否合格","资格审核","鉴定时间"}
    Dim Cols2() As String = {"工作单位","县公司","姓名","性别","身份证号码","文化程度","现岗位名称","参加工作时间","现工种工作时间","原技术资格等级","原等级取得时间","原资格证书工种","原资格证书编号","鉴定等级","申报鉴定工种","鉴定批次","申报性质","用工性质","原人才当量值","备注","照片","是否合格","资格审核","鉴定时间"}
    SystemReady = False
    For Each dr1 As DataRow In DataTables("报名登记表").Select("[资格审核] = True ")
        Dim dr2 As DataRow = DataTables("历史报名表").Find("身份证号码 = '" & dr1("身份证号码") & "' And 鉴定批次 = '" & dr1("鉴定批次") & "'")
        If dr2 Is Nothing Then
            dr2 = DataTables("历史报名表").AddNew
        End If
        For i As Integer = 0 To Cols1.Length -1
            dr2(Cols2(i)) = dr1(Cols1(i))
        Next
    Next
    SystemReady = True
End If

 

上述代码是“资格审核”全部为Ture的人员导出按钮代码，如果是Ture和False的全部导出，该怎么写？是不是可以不要这句？请版主指教？

 

另外我发现随着批次的增多，哪怕我选定的是其中一个批次导过去，时间都很长，这是什么原因？

谢谢版主！！！！！！

“资审通过导出”按钮代码：

Dim Result As DialogResult
Result = MessageBox.Show("确定导出?", "提示", MessageBoxButtons.YesNo, MessageBoxIcon.Question,MessageBoxDefaultButton.Button2)
Dim Cols1() As String = {"工作单位","县公司","姓名","性别","身份证号码","文化程度","现岗位名称","参加工作时间","现工种工作时间","原技术资格等级","原等级取得时间","原资格证书工种","原资格证书编号","鉴定等级","申报鉴定工种","鉴定批次","申报性质","用工性质","原人才当量值","备注","照片","是否合格","资格审核","鉴定时间"}
Dim Cols2() As String = {"工作单位","县公司","姓名","性别","身份证号码","文化程度","现岗位名称","参加工作时间","现工种工作时间","原技术资格等级","原等级取得时间","原资格证书工种","原资格证书编号","鉴定等级","申报鉴定工种","鉴定批次","申报性质","用工性质","原人才当量值","备注","照片","是否合格","资格审核","鉴定时间"}
For Each dr1 As DataRow In DataTables("报名登记表").Select("[资格审核] = True ")
    Dim dr2 As DataRow = DataTables("审核合格表").Find("身份证号码 = '" & dr1("身份证号码") & "' And 鉴定批次 = '" & dr1("鉴定批次") & "'")
    If dr2 Is Nothing Then
        dr2 = DataTables("审核合格表").AddNew
    End If
    For i As Integer = 0 To Cols1.Length -1
        dr2(Cols2(i)) = dr1(Cols1(i))
    Next
Next

以上是原来的代码，运行正常，就是速度很慢！！！！！！！！

            If dr2 Is Nothing Then
                dr1.Add(dr)
            Else
                dr2.Add(dr)
            End If
        Next
    Catch ex As Exception
        MessageBox.Show("资审通过导出失败")
    End Try
    SystemReady = True
    For Each dr As DataRow In dr1
        dr("资格审核") = True
    Next
    For Each dr As DataRow In dr2
        dr("资格审核") = False
    Next
    dr2 = DataTables("审核合格表").AddNew

以上是我修改的代码，但总报错！我没学过编程，所以看了很久的“查询与赋值并存“”说明也没看得很明白，请版主指教！！！！！！谢谢先！！！！！！

谢谢！！！！！！我先改下试试！

还是不行！！！！！！

对不起，我说不行的时候，是在您回答之前发的！！！！！！

主要是例子很大，我对编程写代码也不是很懂，所以老是要麻烦版主，再次表示感谢！有不懂的地方，我还要向版主讨教！

我对这段代码要进行修改，主要是点击按钮之后，要很长时间才会结束！

我看说明里，1万行的记录才用了0.8秒，我这才几千行，要几分钟，这效率差太多了！
