Application.OnLaunched(LaunchActivatedEventArgs) 方法

定义

命名空间:

Microsoft.UI.Xaml

启动应用程序时调用。 重写此方法以执行应用程序初始化并创建新窗口。

protected:
 virtual void OnLaunched(LaunchActivatedEventArgs ^ args) = OnLaunched;

void OnLaunched(LaunchActivatedEventArgs const& args);

protected virtual void OnLaunched(LaunchActivatedEventArgs args);

function onLaunched(args)

Protected Overridable Sub OnLaunched (args As LaunchActivatedEventArgs)

参数

args

LaunchActivatedEventArgs

示例

使用 OnLaunched 创建和激活main窗口。 (创建 WinUI 3 应用时，此代码由 Visual Studio 项目模板提供。)

private Window m_window;

protected override void OnLaunched(Microsoft.UI.Xaml.LaunchActivatedEventArgs args)
{
    m_window = new MainWindow();
    m_window.Activate();
}
