C#の----Func,Action,predicate在WPF中的应用

首先介绍下，winform中可以用this.invoke来实现；wpf中要使用调度器Control.Despite.invoke；

 (Action)(()=>

{

})和

new Action (()=>
{
 button1.Content = "Action";
 })是等价的

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 的交互逻辑
    /// </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";
            }));

        }
    }
}
