Excel出力の解放について質問です。
下記URLを参考に作成しましたが、出力をし終えたときにプロセスを見るとExcelの解放がされません。

助言をもらえないでしょうか？
With SaveFileDialog1
.FileName = savefilename
If .ShowDialog() = Windows.Forms.DialogResult.OK Then
wstrPath = .FileName()
If Func_Excelチェック(wstrPath) = False Then
Exit Function
End If
End If
End With
Dim excel As New Excel.Application
Dim xlbooks As Excel.Workbooks = excel.Workbooks
Dim xlbook As Excel.Workbook = xlbooks.Add
Dim xlsheets As Excel.Sheets = xlbook.Worksheets
Dim xlsheet As Excel.Worksheet = xlsheets.Item(1)
Dim xlCells As Excel.Range
Dim xlRange1 As Excel.Range
xlCells = xlsheet.Cells
Dim i As Integer = 1
作成データテーブルに接続
xlRange1 = xlCells(1, 1)
xlRange1.Value = "工場番号"
MRComObject(xlRange1, True)
While sqlReader.Read
xlRange1 = xlCells(i + 1, 1)
xlRange1(xlCells(i + 1, 1)).Select()
xlRange1.Value = sqlReader("入力_工場番号")
MRComObject(xlRange1, True)
i += 1
End While
excel.DisplayAlerts = False
xlsheet.SaveAs(wstrPath)
'Select Case Val(excel.Version)
'Case 9
'xlbook.SaveAs(Filename:=wstrPath)
'Case 12
'xlbook.SaveAs(Filename:=wstrPath, FileFormat:=56)
'End Select
'MRComObject(xlsheet, True)
excel.DisplayAlerts = True
MRComObject(xlsheet)'xlSheet の解放
MRComObject(xlsheets)'xlSheets の解放
xlbook.Close()'xlBook を閉じる
MRComObject(xlbook)'xlBook の解放
MRComObject(xlbooks)'xlBooks の解放
excel.Quit()'Excelを閉じる
MRComObject(excel)'excel を解放
Private Function Func_Excelチェック(ByVal arg As String) As Boolean
Dim excel As New Excel.Application
Dim xlbooks As Excel.Workbooks = excel.Workbooks
Dim xlbook As Excel.Workbook
excel.Visible = False
excel.Application.DisplayAlerts = False
Try
If System.IO.File.Exists(arg) = True Then
xlbook = xlbooks.Open(arg)
xlbook.SaveAs(arg, FileFormat:=42, CreateBackup:=False)
MRComObject(xlbook, True)
Return True
Else
Return True
End If
Catch ex As Exception
MessageBox.Show("")
Return False
Finally
xlbooks.Close()
MRComObject(xlbooks, True)
excel.Quit()
MRComObject(excel, True)
End Try
End Function
