Dear All,by using Linq,i,m adding some of the nodes to the xml :

XDocument xdoc = new XDocument(new XDeclaration("1", "utf-8", "yes"),
                                         new XComment("XML data manipulation using Linq"),
                                         new XProcessingInstruction("Instruction", "2333"),
                                         new XElement("Subjects",
                                         new XElement("Subject",
                                         new XElement("Physics", "Good"),
                                         new XElement("maths", "Excellent")
                                         )));
            xdoc.Save(@"C:\data.xml");//in this line it was showing an error that the best overloaded method match for system.xml.linq.xdocument.save(system.xml.xmlwriter) has some invalid arguments.How can i solve this problem?

Thanks in advance.

If you're using Silverlight 3 or 4, you could use the SaveFileDialog class to get the user to save the XML file to the local disk.

See (http://msdn.microsoft.com/en-us/library/system.windows.controls.savefiledialog(VS.95).aspx).

To get the XDocument into string form prior to saving just do:

string xml = xdoc.ToString();

yeah it's a silverlight application.Is there any alternative?

Oh, just a second, is this a Silverlight application?

The overloads of XDocument.Save which save to the file system are not supported with that.

On the face of it, it's impossible to get that particular error when you pass XDocument.Save() a string!

The compiler must choose the overload which saves to a file

So, I'm intrigued - are you absolutely sure that the error is occurring on that particular line?
