如何用vb.net给excel加边框

[dm0351]

我按照excel中加边框的宏代码写了点。但是属性值总显示未定义
Selection.Borders(xlDiagonalDown).LineStyle = xlNone ‘xlNone总显示未定义
最好给出具体点的代码

为什么我调用这个函数没有反映啊
Public Sub biankuang()
Dim exl As Excel.Application = New Excel.Application
Dim range As Excel.Range
mWorkSheet = mWorkBook.ActiveSheet
'mWorkSheet.Range("B11").Select()
'With mWorkSheet.Range("B11")
' .Borders.LineStyle = Excel.XlLineStyle.xlContinuous
Me.mWorkSheet.Range(Me.mExlApp.Cells(9, 1), Me.mExlApp.Cells(9, 10)).Select()

With mWorkSheet.Range(Me.mExlApp.Cells(9, 1), Me.mExlApp.Cells(9, 10))
.Borders(XlBordersIndex.xlDiagonalDown).LineStyle = Excel.XlLineStyle.xlLineStyleNone
.Borders(XlBordersIndex.xlDiagonalUp).LineStyle = Excel.XlLineStyle.xlLineStyleNone
.Borders(XlBordersIndex.xlEdgeLeft).LineStyle = Excel.XlLineStyle.xlContinuous
.Borders(XlBordersIndex.xlEdgeTop).LineStyle = Excel.XlLineStyle.xlLineStyleNone
.Borders(XlBordersIndex.xlEdgeBottom).LineStyle = Excel.XlLineStyle.xlLineStyleNone
.Borders(XlBordersIndex.xlEdgeRight).LineStyle = Excel.XlLineStyle.xlContinuous

End With
Me.mWorkSheet.Columns.AutoFit()

'End With





End Sub

Selection.Borders(xlDiagonalDown).LineStyle = Excel.XlLineStyle.xlLineStyleNone

不知你不是想在导出数据到excel中并加上边框？

搂主在代码里加上以下代码即可
private Const xlEdgeBottom = 9
private Const xlEdgeLeft = 7
private Const xlEdgeRight = 10
private Const xlEdgeTop = 8
private Const xlNone = -4142
Const xlDiagonalDown = 5
const xlDiagonalUp = 6
