ダイアログボックスで生成されたExcelファイルを保存します

Question

ボタンクリックでデータテーブルからxlsファイルを生成しています。今、ファイルを保存するパスがファイルを生成する機能にハードコードされています

Function CreateExcelFile(xlFile As String) As Boolean

私がやりたいことを、私は、ユーザーにオプションを提供したい、Excelファイルの作成が完了した時点で新しく作成されたファイルを保存する場所。私は Winformsで新しく、これを行う方法がわかりません。

ファイルを保存する場所をユーザーが選択できるようにするにはどうすればよいですか？

更新： @Claudiusの回答後の作業コード。

Private Sub btnRecExport_Click(sender As Object, e As EventArgs) Handles 
btnRecExport.Click 
Dim file As String = "I:\PSLFRecords.xlsx" 
CreateExcelFile(file) 
Dim sfdRecords As New SaveFileDialog() 
sfdRecords.Filter = "Excel File|*.xls" 
sfdRecords.Title = "Save PSLF Driver Records" 
sfdRecords.ShowDialog() 
If sfdRecords.FileName <> "" Then 
xlWB.SaveAs(sfdRecords.FileName) 
fs.Close() 
End If 
End Sub

あなたが実際に必要とするだろうすべては、ユーザーが選択したパスあなたに返すよう、FolderBrowserDialog Classのちょうど新しいインスタンスです。必要なすべての情報は、すでにドキュメントに記載されています。あなたのニーズに編集したMSDNから

：ここ

Private Sub Button2_Click(ByVal sender As System.Object, _ 
ByVal e As System.EventArgs) Handles Button2.Click 
    ' Displays a SaveFileDialog so the user can save the Image 
    ' assigned to Button2. 
    Dim saveFileDialog1 As New SaveFileDialog() 
    saveFileDialog1.Filter = "Excel File|*.xls 
    saveFileDialog1.Title = "Save an Excel File" 
    saveFileDialog1.ShowDialog() 

    ' If the file name is not an empty string open it for saving. 
    If saveFileDialog1.FileName <> "" Then 
     xlWB.SaveAs(saveFileDialog1.FileName) 
     fs.Close() 
    End If 
End Sub
