vb.net - Excel 与 VB.NET(HRESULT : 0x8002000B (DISP_E_BADINDEX)) 异常

Question

我第一次尝试从 VB.net 创建 Excel 文件。我已经添加了 Microsoft.Office.Excel 引用，导入 Microsoft.Office.Interop

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

    Dim xlApp As Excel.Application
    Dim xlWorkBook As Excel.Workbook
    Dim xlWorkSheet As Excel.Worksheet
    Dim misValue As Object = System.Reflection.Missing.Value

    xlApp = New Excel.ApplicationClass
    xlWorkBook = xlApp.Workbooks.Add(misValue)
    xlWorkSheet = CType(xlWorkBook.Sheets("sheet1"), Excel.Worksheet)
    xlWorkSheet.Cells(1, 1) = "Something here"
    xlWorkSheet.SaveAs("D:\vbexcel.xlsx")

    xlWorkBook.Close()
    xlApp.Quit()
    releaseObject(xlApp)
    releaseObject(xlWorkBook)
    releaseObject(xlWorkSheet)

    MsgBox("Excel file created , you can find the file c:\")

End Sub

错误代码在行中:

   xlWorkSheet = CType(xlWorkBook.Sheets("sheet1"), Excel.Worksheet)

   Invalid index. (Exception from HRESULT: 0x8002000B (DISP_E_BADINDEX))

Answer 1

也许您的 Excel 版本不支持英语。 “sheet”在本地语言中是一个肮脏的词，它有点像英语；)你的名字暗示英语不是默认语言。使用索引而不是名称可以避免这样的意外:

    xlWorkSheet = CType(xlWorkBook.Sheets(1), Excel.Worksheet)
