Reactive Extensions

看异步调用时 看到RX与LINQ用法类似，但是实现机制不同。

Rx最显著的特性是使用可观察集合(Observable Collection)来达到集成异步(composing asynchronous)和基于事件(event-based)的编程的效果。

public partial class MainPage : PhoneApplicationPage
    {
        readonly List<String> fruits = new List<string>{
        "Apple","Orange","Banana","Pears","melon"};
        // 构造函数
        public MainPage()
        {
            InitializeComponent();
            PopulateCollection();
        }

        private void PopulateCollection()
        {
            //使用Enumerable集合进行填充
            fruits.ForEach(fruit => lblEnumerable.Items.Add(fruit));

            //使用Observable集合进行填充
            IObservable<String> observable = fruits.ToObservable();
            observable.Subscribe(fruit => lblObservable.Items.Add(fruit));
        }
    }
