如何序列化/反序列化为字典`来自自定义XML而不使用XElement?

空着Dictionary<int, string>如何用XML中的键和值填充它

<items>

<item id='int_goes_here' value='string_goes_here'/>

</items>

并使用XElement将其序列化回XML?

回答:

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);

回答:


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"));
