Answer 1

Xml文档必须只有一个根元素.但是您尝试在根级别添加两个节点Departments和Employees节点.添加一些根节点来解决此问题:

doc = new XDocument(
    new XElement("RootName",
        new XElement("Employees",
            new XElement("Employee",
                new XAttribute("id", 1),
                new XElement("EmpName", "XYZ"))),

        new XElement("Departments",
                new XElement("Department",
                    new XAttribute("id", 1),
                    new XElement("DeptName", "CS"))))
                );

您需要添加根元素.

doc = new XDocument(new XElement("Document"));
    doc.Root.Add(
        new XElement("Employees",
            new XElement("Employee",
                new XAttribute("id", 1),
                    new XElement("EmpName", "XYZ")),
        new XElement("Departments",
            new XElement("Department",
                new XAttribute("id", 1),
                    new XElement("DeptName", "CS")))));
