Xmlreader and remote large file

I have to 开发者_高级运维read a remote xml file with XmlReader but sometimes I have an exception :

system.net.webexception the operation has timed out.

But i don't know why because it can work or not with the same file.

Anyone have a solution.

As per the description, seems like your network is dropping connections or in other terms its flaky. Hence its a network problem and not a problem with the code.
