FilterIndex 属性

返回或设置一个 Long 类型，表示文件对话框的默认文件筛选。默认筛选决定首次打开文件对话框时显示的文件类型。可读写。

expression.FilterIndex

expression 必需。该表达式返回“应用于”列表中的对象之一。

说明

如果试图将该属性设置为大于筛选数量的数字，将选定最后一个筛选。

示例

本示例使用FileDialog 对象显示“文件选取器”对话框，并在消息框中显示每个选定的文件。本示例还演示如何新添筛选并其成为默认筛选。

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 a String,
    '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 action button...

                'vrtSelectedItem is a String that contains the path of each selected item.
                'You can use any file I/O functions that you want to work with this path.
                'This example simply displays the path in a message box.
                MsgBox "Selected item's path: " & vrtSelectedItem
