在C#中以XML字符串的形式获取特定部分

string xmlString = "<root><person><name>John</name><age>30</age></person></root>";
XDocument doc = XDocument.Parse(xmlString);

var result = from person in doc.Descendants("person")
             select new
             {
                 Name = person.Element("name").Value,
                 Age = person.Element("age").Value
             };

foreach (var item in result)
{
    Console.WriteLine("Name: " + item.Name);
    Console.WriteLine("Age: " + item.Age);
}
