Excel Cell Alignments: Numerical values for e.g. x

问题:

I've been trying to align Excel cell text values. I've tried the more common xlLeft, xlRight but this doesn't seem to work. The error was xlLeft wasn't declared. I am using Visual Studios and creating a aspx page with VB.

Here is a sample of my code:

    Dim oExcel As Object
    Dim oBook As Object
    Dim oSheet As Object

    'Start a new workbook in Excel
    oExcel = CreateObject("Excel.Application")
    oBook = oExcel.Workbooks.Add

    'Add data to cells of the first worksheet in the new workbook
    oSheet = oBook.Worksheets(1)

    oSheet.Range("A1:E1").Merge()
    oSheet.Range("A1").Value = "Hello"
    oSheet.Range("A2:E2").Merge()
    oSheet.Range("A2").Value = "There "
    oSheet.Range("A1:A4").Font.Bold = True
    oSheet.Range("A1").HorizontalAlignment = -4131

回答1:

For VerticalAlignment:

Top:    -4160
Center: -4108
Bottom: -4107

And HorizontalAlignment:

Left:    -4131
Center:  -4108
Right:   -4152

You can use xlLeft:

Imports Microsoft.Office.Interop.Excel

...
oSheet.Range("A1").HorizontalAlignment = Constants.xlLeft

回答3:

xcl.Range("J:J").EntireColumn.HorizontalAlignment = _
Microsoft.Office.Interop.Excel.Constants.xlCenter
