委托事件 简写 C#

public MainPage()

{

this.InitializeComponent();

//简写

this.Loaded += (sender, e) => { MessageBox.Show("d"); MessageBox.Show("ss"); };

//原来写法

this.Loaded +=new RoutedEventHandler(MainPage_Loaded);

}

void MainPage_Loaded(object sender, RoutedEventArgs e)

{

//简写

this.Dispatcher.BeginInvoke(() => MessageBox.Show("dd"));

//原来写法

this.Dispatcher.BeginInvoke(test);

}

void test()

{

MessageBox.Show("dd");

}

结合 Action 的使用
