Answer 1

试试这个:

string text = "<foo>...</foo>";
var pairs = XDocument.Parse(text)
                     .Descendants("add")
                     .Select(x => new { Key = x.Attribute("key").Value,
                                        Value = x.Attribute("Value").Value })
                     .ToList();
