Answer 1

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

// ...

using (var writer = XmlWriter.Create("output.xml"))
     new XDocument(
        new XDeclaration("1.0", "UTF-8", null),
        new XElement("pages",
            Enumerable.Range(1, 4)
                .Select(i => new XElement("page",
                                  new XAttribute("name", "Page Name " + i),
                                  new XAttribute("url", "/page-" + i + "/"))))
     ).WriteTo(writer);

Answer 2

A fairly simple way might be this:

XmlWriterSettings settings = new XmlWriterSettings();
settings.Encoding = Encoding.UTF8;
settings.Indent = true;
using (XmlWriter writer = XmlWriter.Create(@"c:\path\file.xml", settings))
{

    writer.WriteStartElement("pages");

    for (int i = 1; i < 5; i++)
    {
        writer.WriteStartElement("page");
        writer.WriteAttributeString("name", "Page Name " + i.ToString());
        writer.WriteAttributeString("url", string.Format("/page-{0}/", i));
        writer.WriteEndElement(); // page
    }
    writer.WriteEndElement(); // pages
}

, - :

System.Xml.XmlTextWriter writer = new System.Xml.XmlTextWriter(Server.MapPath("pages.xml"), System.Text.Encoding.UTF8);

        writer.WriteStartDocument();
        writer.WriteStartElement("pages");

        writer.WriteStartElement("page");
        writer.WriteAttributeString("name", "Page name 1");
        writer.WriteAttributeString("url", "Page url 1");
        writer.WriteEndElement();

        writer.WriteStartElement("page");
        writer.WriteAttributeString("name", "Page name 2 ");
        writer.WriteAttributeString("url", "Page url 2");
        writer.WriteEndElement();

        writer.WriteStartElement("page");
        writer.WriteAttributeString("name", "Page name 3");
        writer.WriteAttributeString("url", "Page url 3");
        writer.WriteEndElement();

        writer.WriteEndElement();
        writer.WriteEndDocument();
        writer.Close();

Answer 5

using System.Xml;
//...
XmlDocument xmldoc = new XmlDocument();
XmlElement pages = xmldoc.CreateElement("pages");
XmlElement page = null;

for(int i = 1; i <= 4; i++)
{
    page = xmldoc.CreateElement("page");
    page.SetAttribute("name", "Page Name " + i);
    page.SetAttribute("url", "/page-" + i + "/");
    pages.AppendChild(page);
}

xmldoc.AppendChild(xmldoc.CreateXmlDeclaration("1.0", "UTF-8", null));
xmldoc.AppendChild(pages);
xmldoc.Save("output.xml");
