Is there a way to set a timeout on System.Linq.Xml.XDocument.Load(string uri)? Or should I use the technique described in http://stackoverflow.com/questions/299198/implement-c-generic-timeout?

推荐答案

没有什么内置据我所知。您可以获取XML内容自己与的WebRequest 的一个实例（您可以的设置超时），然后直接将XML数据的 XDocument.Load 方法。

There is nothing built-in as far as I'm aware. You can fetch the XML content yourself with an instance of WebRequest (which you can set a timeout on) and then pass the XML data directly to the XDocument.Load method.

从技术上讲，最稳健的解决办法是实行的XmlResolver 自己它采用了的WebRequest 中的 GetEntity（）的实施做了超时。然后创建一个的XmlReader 根据你的的XmlResolver 并通过的XmlReader 到 XDocument.Open 。

Technically, the most "robust" solution would be to implement XmlResolver yourself which uses a WebRequest in the GetEntity() implementation to do a timeout. Then create an XmlReader based on your XmlResolver and pass the XmlReader to XDocument.Open.

我说，会更稳健的原因是，如果XML文件引用的等的Web服务器上的实体（如DTD），那么你可能会想超时办理该还有，不只是初始请求。

The reason I say that would be more "robust" is that if the XML file references other entities on the web server (e.g. a DTD) then you would probably want the timeout to apply for that as well and not just the initial request.
