关键代码

Dim dtStart As DateTime = TimeZone.CurrentTimeZone.ToLocalTime(new DateTime(1970, 1, 1))

Dim lTime As Double = Double.Parse("0.336805555555556")

Dim toNow As TimeSpan = new TimeSpan(lTime)

MessageBox.show(dtStart.Add(toNow))

这种情况，就尽量不要用二维数组导入了，直接用原始的导入

Dim dlg As New OpenFileDialog
dlg.Filter= "所有文件|*.*|Excel2003文件|*.xls|Excel2007文件|*.xlsx" '设置筛选器
If dlg.ShowDialog = DialogResult.Ok Then '如果用户单击了确定按钮

    MessageBox.Show("你选择的是:" & dlg.FileName,"提示")
    If MessageBox.Show("是否合并?","请确认!",MessageBoxButtons.OKCancel,MessageBoxIcon.Question) = DialogResult.OK Then
        DataTables("sheet2").StopRedraw

        Dim App As New MSExcel.Application
        try
            Dim Wb As MSExcel.WorkBook = App.WorkBooks.Open(dlg.FileName)
            Dim Ws As MSExcel.WorkSheet = Wb.WorkSheets(1)
            Dim Rg As MSExcel.Range = Ws.UsedRange
            For n As Integer = 2 To rg.Rows.Count
                Dim ro As Row = Tables("sheet2").AddNew
                For i As Integer = 0 To Tables("sheet2").Cols.Count - 1
                    ro(i) = ws.Cells(n,i+1).Text
                Next
            Next
            MessageBox.Show("导入成功!","恭喜!")
        catch ex As exception
            msgbox(ex.message)
            MessageBox.Show("导入失败!","恭喜!")
        finally
            DataTables("sheet2").ResumeRedraw
            app.quit
        End try

    Else
        Return
    End If
End If

地道，接地气~~~灵光。多谢

亦可用Date.FromOaDate把數值轉為日期:

如:

Dim v1 As Double = 0.35765

Dim d1 As Date

d1 = Date.FromOaDate(v1)

Output.show(d1) ' 8:35:00

帅哥~~~请问，您的代码如何扩展出“指定导入需要的列”？

您的导入是全部倒入！

目前：

状况1：导入表到项目中的一个临时表里，因为excel表数据忒粗，不规范，废行太多。我目前是在该表中设立“逻辑判断列”，上述代码导入会在逻辑列认为“只读”，而导致导入错误。

状况2：原excel表有无用列，只想导入需要的数据列！

谢谢！

如下处理

Dim dlg As New OpenFileDialog
dlg.Filter= "所有文件|*.*|Excel2003文件|*.xls|Excel2007文件|*.xlsx" '设置筛选器
If dlg.ShowDialog = DialogResult.Ok Then '如果用户单击了确定按钮

    MessageBox.Show("你选择的是:" & dlg.FileName,"提示")
    If MessageBox.Show("是否合并?","请确认!",MessageBoxButtons.OKCancel,MessageBoxIcon.Question) = DialogResult.OK Then
        DataTables("sheet2").StopRedraw

        Dim App As New MSExcel.Application
        try
            Dim Wb As MSExcel.WorkBook = App.WorkBooks.Open(dlg.FileName)
            Dim Ws As MSExcel.WorkSheet = Wb.WorkSheets(1)
            Dim Rg As MSExcel.Range = Ws.UsedRange
            Dim cs() As String = {"起始时间", "落地时间"}
            For n As Integer = 2 To rg.Rows.Count
                Dim ro As Row = Tables("sheet2").AddNew
                For i As Integer = 0 To cs.length - 1
                    ro(cs(i)) = ws.Cells(n,i+1).Text
                Next
            Next
            MessageBox.Show("导入成功!","恭喜!")
        catch ex As exception
            msgbox(ex.message)
            MessageBox.Show("导入失败!","恭喜!")
        finally
            DataTables("sheet2").ResumeRedraw
            app.quit
        End try

    Else
        'Return
    End If
End If

多谢~~~再次灵光！
