MVC从Web服务解析XML

Question

I am trying to parse the xml results from a web service but I am getting an error {The best overloaded method match for 'System.Xml.Linq.XElement.Parse(string)' has some invalid arguments"}

var service = new RemoteService.RemoteSoapClient("RemoteSoap");
var result = service.GetDetails(systemId, appId);

ViewBag.Surname = XElement.Parse(result).Descendants("Customer").Single().Attribute("Surname").Value;

XML Output

<?xml version="1.0" encoding="UTF-8"?>
-<List>
-<Customer>
<Surname>Spack</Surname>
<Firstname>Bob</Firstname>
</Customer>
</List>

What am I doing wrong, please help.

Answer 1

If you F12 XElement.Parse you can see it only has two separate method signatures, in both of which the expected first parameter is a string. I'm going to guess service.GetDetails does not return a string.

If you throw a .ToString() at the end of your ViewBag.Surname assignment that should at least get you out of your compile error. Whether or not that actually gets you the data you expect, hard to say.

Answer 2

As the error message suggested, XElement.Parse() expect string as argument (instead of XmlDocument as you currently passed).

You can use XmlDocument.OuterXml to get string markup representation of XmlDocument :

ViewBag.Surname = XElement.Parse(result.OuterXml)
                          .Descendants("Customer")
                          .Single()
                          .Element("Surname")
                          .Value;
