使用introp将其打开到vb.net后，Excel崩溃

Followig是我用于从Excel导入数据的代码

Dim misValue As System.Reflection.Missing Dim tbl As New System.Data.DataTable Dim xlApp As nExcel.Application Dim xlWorkBook As nExcel.Workbook Dim xlWorkSheet As nExcel.Worksheet xlApp = New nExcel.Application Try xlWorkbook = xlApp.Workbooks.Open(sFilePath) Dim issheetext As Boolean Dim sheet As nExcel.Worksheet For Each sheet In xlWorkbook.Sheets If sheet.Name.Equals(sSheetname) Then issheetext = True Exit For End If Next If issheetext Then xlWorkSheet = DirectCast(xlWorkbook.Sheets(sSheetname), nExcel.Worksheet) ' get range object Dim myRange As nExcel.Range = DirectCast(xlWorkSheet.get_Range("A1:BZ102451"), nExcel.Range) For i As Integer = 0 To myRange.Columns.Count Dim cellval As Object cellval = DirectCast(myRange.Cells(1, i + 1), Object) tbl.Columns.Add(cellval.ToString(), cellval.GetType()) Next For i As Integer = 0 To myRange.Rows.Count - 2 tbl.Rows.Add() For j As Integer = 0 To myRange.Columns.Count - 1 Dim CellValue As Object = DirectCast(myRange.Cells(2 + i, j + 1).Value2, Object) tbl.Rows(i)(j) = CellValue Next Next End If Catch ex As Exception Finally Try releaseObject(xlWorkSheet) releaseObject(xlWorkbook) releaseObject(xlApp) Catch End Try End Try Return tbl 

但是当debugging器跨xlWorkbook = xlApp.Workbooks.Open(sFilePath)

它显示了我

并在例外，它显示了我

远程过程调用失败。 （从HRESULTexception：0x800706BE）
