另外，ASP.NET AJAX 的问题是它有点头重脚轻。 通过使用 JQuery，您可以从常规 ASP.NET Web 表单、MVC 中的视图调用您的 Web 服务，或者实际上使用任何其他 Web 技术（经典 ASP、PHP 等等），所有这些都从客户端使用，在我的view，最好的 javascript 框架。 :)
I would create a script callable Web Service and use JQuery.
Here's a good guide on using JQuery to call an ASP.NET (ASMX) web service:
Now, you would just poll this web service at whatever interval makes sense for your application.
Also, the problem with ASP.NET AJAX is it's a bit top heavy. By using JQuery, you can call your web service from a regular ASP.NET web form, from a View in MVC, or actually using any other web technology (classic ASP, PHP, whatever) all from the client side using just, in my view, the best javascript framework around. :)
Try out WebSync, a scalable comet server built for .NET/IIS. It'll let you push data nicely from the server, and integrates super easily with ASP.NET projects (a couple web.config entries is all it takes).
PokeIn is a reverse ajax library for ASP.NET & Mono. It has various capabilities like .NET to JSON vice versa. You may download sample projects from here
To do that, use ASP.NET 3.0/3.5 or if you are using earlier versions, use ASP.NET Ajax. However both examples listed by you, are using Ajax to pull information, not push it.

我将创建一个可调用 Web 服务的脚本并使用 JQuery。
以下是有关使用 JQuery 调用 ASP.NET (ASMX) Web 服务的良好指南：

现在，您将只需以对您的应用程序有意义的任意时间间隔轮询此 Web 服务即可。

您正在寻找的推送技术称为彗星。 请参阅本文获取一些指导。
The push technique you are looking for is called Comet. See this article for some pointers.
尝试 WebSync，这是一个为 .NET/IIS 构建的可扩展 Comet 服务器。 它可以让您很好地从服务器推送数据，并超级轻松地与 ASP.NET 项目集成（只需几个 web.config 条目即可）。

PokeIn 是 ASP.NET 的反向 ajax 库; 单核细胞增多症。 它具有各种功能，例如 .NET 到 JSON，反之亦然。 您可以从此处下载示例项目

为此，请使用 ASP.NET 3.0/3.5，或者如果您使用的是早期版本，请使用 ASP.NET Ajax< /a>. 然而，您列出的两个示例都使用 Ajax 来提取信息，而不是推送信息。
To do that, use ASP.NET 3.0/3.5 or if you are using earlier versions, use ASP.NET Ajax. However both examples listed by you, are using Ajax to pull information, not push it.
既然您提到了
ASP.NET，您应该使用SignalR。请参阅我的其他答案：即时通知，例如 Facebook
Since you mention
ASP.NETyou should be usingSignalR.See my other answer here: Instant notifications like Facebook
