示例

文件选取器示例演示如何在文件选取器中显示任何类型的文件。

此简短示例代码演示了在请求的位置打开的 FilePicker。

private async void Button_click(object sender, RoutedEventArgs e)
{
    FileOpenPicker filePicker = new FileOpenPicker();
    filePicker.SuggestedStartLocation = PickerLocationId.DocumentsLibrary;
    filePicker.ViewMode = PickerViewMode.List;
    filePicker.FileTypeFilter.Add(".txt");
    StorageFile file = await filePicker.PickSingleFileAsync();
}

注解

SuggestedStartLocation 并不总是用作文件夹选取器起始位置。 为了为用户提供一致性感，文件夹选取器会记住用户导航到的最后一个位置，并且通常从该位置开始。
