Why is my XDocument saving the declaration when I don't want it to?

Question

I have the following code:

class Program
{
    static void Main(string[] args)
    {
        using (var stream = File.Create(@\"C:\\test.xml\"))
        {
           


        

Answer 1

Instead XDocument.Save() you can use XmlWriter with XmlWriterSettings.OmitXmlDeclaration set to true

using System.IO;
using System.Xml;
using System.Xml.Linq;

XmlWriterSettings xws = new XmlWriterSettings();
xws.OmitXmlDeclaration = true;
xws.Indent = true;

using (var stream = File.Create(@"C:\test.xml"))
using (XmlWriter xw = XmlWriter.Create(stream, xws))
{
    var xml = new XElement(
        "root",
        new XElement("subelement1", "1"),
        new XElement("subelement2", "2"));

    xml.Save(xw);
}
