FileActivatedEventArgs 类

定义

激活应用时提供数据,因为它是与文件关联的应用。

示例

Application 对象上的 OnFileActivated 事件处理程序接收所有文件激活事件。

protected override void OnFileActivated(FileActivatedEventArgs args)
{
       // TODO: Handle file activation

       // The number of files received is args.Files.Size
       // The first file is args.Files[0].Name
}
Private Sub OnFileActivated(ByVal args As Windows.ApplicationModel.Activation.FileActivatedEventArgs)
      ' TODO: Handle file activation

      ' The number of files received is args.Files.Size
      ' The first file is args.Files(0).Name
End Sub
void App::OnFileActivated(Windows::ApplicationModel::Activation::FileActivatedEventArgs const& /* args */)
{
    // TODO: Handle file activation.

    // The number of files received is args.Files().Size().
    // The first file is args.Files().GetAt(0).Name().
}
void App::OnFileActivated(Windows::ApplicationModel::Activation::FileActivatedEventArgs^ args)
{
       // TODO: Handle file activation

       // The number of files received is args->Files->Size
       // The first file is args->Files->GetAt(0)->Name
}

注解

ActivationKindFile 时,实现事件处理程序以响应 Activated 事件时,将访问此对象。

使用 C++、C# 或 Visual Basic 的 UWP 应用通常通过重写 Application 对象的方法来实现激活点。 默认模板 app.xaml 代码隐藏文件始终包含 OnLaunched 的替代,但为其他激活点(如 OnFileActivated )定义替代取决于应用代码。

激活方案涉及的所有 应用程序 替代都应在其实现中调用 Window.Activate

请注意,为文件协定激活应用时,必须使用通过 Files 属性传递给应用的 StorageFile 对象访问数据。 不应尝试访问文件的路径,因为你的应用可能没有对文件位置的权限。
