What's the question?

sharmarun 14-May-13 8:19am

want to remove

?xml version="1.0" encoding="utf-8" standalone="yes" ?

XML decleration

[no name] 14-May-13 8:25am

Okay... and? What is the problem with the code that you have written that prevents you from removing that one line of text?

see the code

root = new XElement("AriReport");
xDoc = new XDocument(new XDeclaration("1.0", "utf-8", "yes"),root);
xDoc.Element("AriReport").Add(new XAttribute("RowCount", people.Count()));
root.Add(people);

if (!File.Exists(saveLocation))
{
xDoc.Save("C:\\ShoreFollowUp.xml");

}
XDeclaration dec = new XDeclaration("", "", "");
xDoc.Declaration = dec;
xDoc.WriteTo("C:\\ShoreFollowUp.xml");

but this line didnt removed

Hi sharmarun,
Did you check all constructors available for XDocument class? Check here
You need to instance XDocument class with no declaration element/object.

For example:

XDocument doc = new XDocument();
doc.Add(new XComment("This is a comment"));
doc.Add(new XElement("Root", "content"));
Console.WriteLine(doc);

You will have the following output:

XML

<!--This is a comment-->
<Root>content</Root>

Bye.

An XML file normally has a header line such as you describe - it is optional, but recommended, and XDocument always adds it when you use the Save method.

If it really disturbs you, you need to use an XmlWriter instead - it has an option to turn it off.

C#

XDocument doc = new XDocument(new XElement("MyElement", new XAttribute("MyKey", "MyValue")));
XmlWriterSettings xws = new XmlWriterSettings();
xws.OmitXmlDeclaration = true;
StringWriter sw = new StringWriter();
using (XmlWriter xw = XmlWriter.Create(sw, xws))
     {
    doc.Save(xw);
    }

Solution 3

I would start by understanding XLinq since it is the newest XML technology from Microsoft. There are also other ways of doing it, but probably want to use the newest: XLINQ Introduction Part 3 Of 3[^]
