c# - This operation would create an incorrectly structured document

Question

I am new to XML and tried the following but I'm getting an exception. Can someone help me?

The exception is This operation would create an incorrectly structured document

My code:

string strPath = Server.MapPath("sample.xml");
XDocument doc;
if (!System.IO.File.Exists(strPath))
{
    doc = new XDocument(
        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"))));

    doc.Save(strPath);
}

Xml document must have only one root element. But you are trying to add both Departments and Employees nodes at root level. Add some root node to fix this:

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"))))
                );
