C#子线程更新UI

WPF中使用：

            Task.Run(() =>
            {
                Console.WriteLine("222222-{0}", Thread.CurrentThread.ManagedThreadId);
                Application.Current.Dispatcher.Invoke(new Action(() =>
                {
                    Console.WriteLine("333333-{0}", Thread.CurrentThread.ManagedThreadId);
                }));
                Console.WriteLine("444444-{0}", Thread.CurrentThread.ManagedThreadId);
            });

            Task.Run(() =>
            {
                Console.WriteLine("222222-{0}", Thread.CurrentThread.ManagedThreadId);
                Application.Current.Dispatcher.BeginInvoke(new Action(() =>
                {
                    Console.WriteLine("333333-{0}", Thread.CurrentThread.ManagedThreadId);
                }));
                Console.WriteLine("444444-{0}", Thread.CurrentThread.ManagedThreadId);
            });

WinForm中使用：

            Task.Run(() =>
            {
                Console.WriteLine("222222-{0}", Thread.CurrentThread.ManagedThreadId);
                Invoke(new Action(() =>
                {
                    Console.WriteLine("333333-{0}", Thread.CurrentThread.ManagedThreadId);
                }));
                Console.WriteLine("444444-{0}", Thread.CurrentThread.ManagedThreadId);
            });

            Task.Run(() =>
            {
                Console.WriteLine("222222-{0}", Thread.CurrentThread.ManagedThreadId);
                BeginInvoke(new Action(() =>
                {
                    Console.WriteLine("333333-{0}", Thread.CurrentThread.ManagedThreadId);
                }));
                Console.WriteLine("444444-{0}", Thread.CurrentThread.ManagedThreadId);
            });
