Answer 1

I don't know if it's possible to change the XmlReader timeout, but maybe you can do something different:

Use WebRequest to get the xml (this does have a Timeout property) and feed XmlReader this xml after you have received it:

WebRequest request = WebRequest.Create(url);
request.Timeout = 5000;

using (WebResponse response = request.GetResponse())
using (XmlReader reader = XmlReader.Create(response.GetResponseStream()))
{
    // Blah blah...
}

You may also want to look into threading to spin this process off onto a background thread so it doesn't block your UI, if that's a concern in your case. – Kmeson

i was expecting that this is only option. Thank you for detailed code – Forworn

You can create your own WebRequest and create an XmlReader from the response stream. See the response to this question for details:

Prevent or handle time out with XmlReader.Create(uri)

Pass your own stream to the XmlReader.Create call. Set whatever timeout you like.

Another option is to do this

var settings = new XmlReaderSettings();
settings.XmlResolver = resolver;

// Create the reader.
XmlReader reader = XmlReader.Create("http://serverName/data/books.xml", settings);

Where the resolver instance is a custom class that changes the url fetching behavior as described in the documentation at the link below.
