如何在C＃中实现Javascript的XmlHttpRequest？

Question

There is an old article in the MSDN Magazine with a walk-through to implement in C# the equivalent of the Javascript XMLHttpRequest object.

I find it very interesting but the code is not downloadable anymore.

Do you know of an implementation similar to the Javascript XMLHttpRequest object but in C#? Among other thinks, this implementation can:

• Send http requests to the server.
• Send requests both synchronously and asynchronously.
• Allows to abort long running processes.

I know it all can be done easily with the HTTPWebRequest object in .NET, but after reading the article I was hoping that a wrapper would be available as it used to be in the code of that article (the link is dead).

Thanks,

Answer 1

看一下WebClient类 。

Answer 2

You can use WebClient.DownloadString that is a good wrapper around a web request. You can have a non blocking call too ( the better way ) by using DownloadStringAsync

Answer 3

You can use WebClient, though I often find it wraps a bit too much and I end up going back to HTTPWebRequest.

There's plenty of the code from that article in it's figures at http://msdn.microsoft.com/hr-hr/magazine/bb985675%28en-us%29.aspx Enough really to reconstruct the whole thing.
