        XDocument doc = new XDocument(
            new XDeclaration("1.0", "utf-8", "yes"),
            new XElement("root",
                new XElement("companyId", "1")

        );

 

        string kk = doc.ToString();

---------
        XDocument doc = new XDocument(new XDeclaration("1.0", "utf-8", "yes"));
        XElement root = new XElement("root");

        XElement element = new XElement("companyId");
        element.Value = 1 + "";
        root.Add(element);

        doc.Add(root);

元素讀取

        XElement els = XElement.Parse(msg);
        var companyId = from e in els.Elements("companyId")
                        select e;
        string kk = companyId.First().Value;
