doc.Save("data.xml"); Not working c#

Question

As the headline states, when i try to use doc.Save("data.xml"); it gives me the error "Argument 1: cannot convert from 'string' to 'System.IO.Stream'

I've tried both of these:

public void holder()
    {
        string location = "Employees.xml";
        XDocument doc = XDocument.Load(location);
        XElement person = doc.Element("Person");
        person.Add(new XElement("Employee",
                   new XElement("Name", "David"),
                   new XElement("Dept", "Chef")));
        doc.Save(location);
    }


 public void holder()
    {

        XDocument doc = XDocument.Load("Employees.xml");
        XElement person = doc.Element("Person");
        person.Add(new XElement("Employee",
                   new XElement("Name", "David"),
                   new XElement("Dept", "Chef")));
        doc.Save("Employees.xml");
    }

The loading part gives me no problems, its the saving..

Have you tried without the name of the file, just `doc.Save()`? — David Espino, Oct 07 '16 at 23:06
It should work, XDocument does seem to have an overload for Save accepting a string. Are you using Silverlight by any chance? Review that your reference to System.Xml.Linq is the one you expect. — Fredy Treboux, Oct 07 '16 at 23:38
I am using Visual studio? Dunno if that is what you mean.. And i dunno about the last part either. I have System.Xml.Linq declared. — Hudlommen, Oct 07 '16 at 23:52
Arh i found something, i am writing a UWA for windows 10. Its in that file that it does not work. When i do it in a console application it all works fine. Any ideas of how to make it work in a UWA? — Hudlommen, Oct 08 '16 at 00:02

For UWA you need to use the overload that accepts a stream, once you get a stream for the file you want to open just pass it in.

public void holder(Stream input, Stream output) {

    XDocument doc = XDocument.Load(input);
    XElement person = doc.Element("Person");
    person.Add(new XElement("Employee",
               new XElement("Name", "David"),
               new XElement("Dept", "Chef")));
    doc.Save(output);
}

To see how to get the input and output streams on a UWA program see this question
