C#の----Func,Action,predicate在WPF中的應用

標籤：event   ica   rgs   put   ati   pes   object   system   component   

首先介紹下，winform中可以用this.invoke來實現；wpf中要使用調度器Control.Despite.invoke；

 (Action)(()=>

{

})和

new Action (()=>
            {
                button1.Content = "Action";
            })是等價的

using System.Windows.Data;using System.Windows.Documents;using System.Windows.Input;using System.Windows.Media;using System.Windows.Media.Imaging;using System.Windows.Navigation;using System.Windows.Shapes;namespace WpfApplication1_weituoTest{    /// <summary>    /// MainWindow.xaml 的互動邏輯    /// </summary>    public partial class MainWindow : Window    {        public MainWindow()        {            InitializeComponent();        }        private void button1_Click(object sender, RoutedEventArgs e)        {            //button1.Dispatcher.BeginInvoke((Action)(() =>             //{            //    button1.Content = "Action";            //}));            button1.Dispatcher.BeginInvoke(new Action (()=>            {                button1.Content = "Action";            }));        }    }}
