在一个临时item班的帮助下
public class item
{
[XmlAttribute]
public int id;
[XmlAttribute]
public string value;
}
样本字典：
Dictionary<int, string> dict = new Dictionary<int, string>()
{
{1,"one"}, {2,"two"}
};
。
XmlSerializer serializer = new XmlSerializer(typeof(item[]),
new XmlRootAttribute() { ElementName = "items" });
serializer.Serialize(stream,
dict.Select(kv=>new item(){id = kv.Key,value=kv.Value}).ToArray() );
var orgDict = ((item[])serializer.Deserialize(stream))
.ToDictionary(i => i.id, i => i.value);
如果您改变主意，可以 使用XElement 完成此 操作 。
XElement xElem = new XElement(
"items",
dict.Select(x => new XElement("item",new XAttribute("id", x.Key),new XAttribute("value", x.Value)))
);
var xml = xElem.ToString(); //xElem.Save(...);
XElement xElem2 = XElement.Parse(xml); //XElement.Load(...)
var newDict = xElem2.Descendants("item")
.ToDictionary(x => (int)x.Attribute("id"), x => (string)x.Attribute("value"));
