asp.net – Excel单元格对齐：例如,数值xlLeft,xlRight还是xlCenter？

我一直在尝试对齐Excel单元格文本值.我尝试过更常见的xlLeft,xlRight,但这似乎不起作用.错误是xlLeft未声明.我正在使用Visual Studios并使用VB创建一个aspx页面.

以下是我的代码示例：

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

解决方法

对于VerticalAlignment：

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

和Horizo​​ntalAlignment：

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