Easy way to convert a Dictionary to xml and vice versa

Dictionary to Element:

Dictionary<string, string> dict = new Dictionary<string,string>();
XElement el = new XElement("root",
    dict.Select(kv => new XElement(kv.Key, kv.Value)));

Element to Dictionary:

XElement rootElement = XElement.Parse("<root><key>value</key></root>");
Dictionary<string, string> dict = new Dictionary<string, string>();
foreach(var el in rootElement.Elements())
{
   dict.Add(el.Name.LocalName, el.Value);
}
