无法选择报告Excel xls文件（错误：外部表格不是预期的格式）

Question

Try
    Dim path As String = String.Concat((Server.MapPath("~/temp/" + CCAM_Browe.FileName)))
    CCAM_Browe.PostedFile.SaveAs(path)
    Using OleDBcon As New OleDbConnection("Provider=Microsoft.Ace.OLEDB.12.0;Data Source=" + path + ";Extended properties=Excel 12.0;")
        Using cmd As New OleDbCommand("Select * from [Sheet1$]", OleDBcon)
            Using objAdapterr1 As New OleDbDataAdapter(cmd)
                OleDBcon.Open()
                Dim dr As DbDataReader = cmd.ExecuteReader()
                Dim con_str As String = "Data Source=GFCKUL-A0027716\;Initial Catalog=Inbound_VSM;Integrated Security=True"
                Using bulkInsert As SqlBulkCopy = New SqlBulkCopy(con_str)
                    bulkInsert.DestinationTableName = "test"
                    bulkInsert.WriteToServer(dr)
                End Using
                OleDBcon.Close()
                lblMsg.Text = "Upload Successful"
                File.Delete(Convert.ToString(CCAM_Browe.PostedFile.FileName))

            End Using
        End Using
    End Using
Catch ex As Exception
    lblMsg.Text = "Upload Unsuccessful, Please contact Administrator to assist"
End Try

错误发生在第OleDBcon.open()行。我已经厌倦了这个问题，我目前安装了 Microsoft Excel 2013 32-bit 。

如果该代码不是报告Excel文件，则此代码可以正常工作。

请帮帮我！谢谢！
