反应扩展（RX）的教程，是最新的 [英] Reactive Extension (Rx) tutorial that is up to date

问题描述

我在无扩展颇感兴趣，但我不能找到一个最新的教程。我开始与固化异步蓝调与.NET 无功扩展，但它是过时的。我可以找出一些变化，但我不能得到的例子很多工作。

I am quite interested in Reactive Extensions but I cannot find an up to date tutorial. I started with Curing the asynchronous blues with the Reactive Extensions for .NET but it is out of date. I can figure out some changes but I could not get many examples working.

我在网上找到了很多文章，主要是从2009，2010年，但他们也是不符合的当前版本。我在使用接收随着Windows Phone和Web客户端特别感兴趣：

I found many articles on the web, mainly from 2009,2010 but they are also incompatible with the current release. I am especially interested in using Rx with Windows Phone and WebClient:

WebClient wc = new WebClient();

var o = Observable.FromEvent<DownloadStringCompletedEventArgs>(wc, "DownloadStringCompleted").Select(newString => newString.EventArgs.Result);

// Subscribe to the observable, and set the label text
o.Subscribe(s => myLabel.Text = s);

// Start the download
wc.DownloadStringAsync(new Uri("http://www.data.com/service"));

不要再工作和更换 FromEvent 与 FromEventPattern 是远远不够的。

有人可以点我一个最新的资源？

Can somebody point me to an up to date resource?

推荐答案

在学习接收的第一件事情是了解背后的IObservable的理念和它如何基于推送性质与IEnumerable的比较。我建议以下一个一个很好的解释：的 A [诺特尔]简单教程无扩展

When learning Rx the first thing is to understand the philosophy behind IObservable and how it's push based nature compares with IEnumerable. I suggest the following one for a good explanation: A[nother] Simpler Tutorial for Reactive Extensions

坎贝尔利具有良好的一系列解释API和何时使用它们。 他还试图使它保持最新与最新版本：的无功用于扩展.NET中介绍
该系列现在可作为一本书的介绍RX

Lee Campbell has nice series explaining the api and when to use them. He also tries to keep it up to date with latest releases: Reactive Extensions for .NET an Introduction The series is now available as a book at Introduction to Rx

顺便说一句，我也写了一个博客张贴关于解决现实生活中的问题与RX：的从数据库使用流数据的反应扩展

By the way, I have also written a blog post about solving real life problem with rx: Using Reactive Extensions for Streaming Data from Database
