備註

如果試圖設定此屬性為大於篩選數字的數字，則要選取最後可用的篩選。

範例

下列範例會使用 FileDialog 物件顯示 [檔案選擇器] 對話方塊，並在訊息方塊中顯示每個選取的檔案。 此範例也會示範如何新增新的檔案篩選器以及如何設定為預設篩選器。

Sub Main() 
 
 'Declare a variable as a FileDialog object. 
 Dim fd As FileDialog 
 
 'Create a FileDialog object as a File Picker dialog box. 
 Set fd = Application.FileDialog(msoFileDialogFilePicker) 
 
 'Declare a variable to contain the path 
 'of each selected item. Even though the path is aString, 
 'the variable must be a Variant because For Each...Next 
 'routines only work with Variants and Objects. 
 Dim vrtSelectedItem As Variant 
 
 'Use a With...End With block to reference the FileDialog object. 
 With fd 
 
 'Add a filter that includes GIF and JPEG images and make it the second item in the list. 
 .Filters.Add "Images", "*.gif; *.jpg; *.jpeg", 2 
 
 'Sets the initial file filter to number 2. 
 .FilterIndex = 2 
 
 'Use the Show method to display the File Picker dialog box and return the user's action. 
 'If the user presses the button... 
 If .Show = -1 Then 
 
 'Step through each string in the FileDialogSelectedItems collection. 
 For Each vrtSelectedItem In .SelectedItems 
 
 'vrtSelectedItem is aString that contains the path of each selected item. 
 'Use any file I/O functions that you want to work with this path. 
 'This example displays the path in a message box. 
 MsgBox "Selected item's path: " & vrtSelectedItem 
 
 Next vrtSelectedItem 
 'If the user presses Cancel... 
 Else 
 End If 
 End With 
 
 'Set the object variable to Nothing. 
 Set fd = Nothing 
 
End Sub
