如何序列化匿名类型对象到XML？ [英] How to serialize Anonymous-typed Objects to XML?

问题描述

有序列化到一个XML字符串动态创建对象的任何可能的方式？

  VAR foobar的=新{FOO =酒吧};
XML字符串= ConvertToXMLString（FOOBAR）;
// XML应该是这样的：
//＆LT;富＆GT;巴≤; /富＆GT;
 

我能看看的XMLSerializer和DataContractSerializer的，但XMLSerializer的要求的对象类型，而DataContractSerializer的要求就需要被序列化属性的属性。

出于绝望，我转换的对象以JSON第一和JSON其转换为XML。

  VAR foobar的=新{FOO =酒吧};
JavaScriptSerializer JS =新JavaScriptSerializer（）;
jsonString = js.Serialize（值）;
//Json.NET在http：//json.$c$cplex.com/
XmlDocument的DOC =（XmlDocument的）JsonConvert.DeserializeXmlNode（jsonString）;
 

解决方案

不使用标准的内置串行器，无; 的XmlSerializer 要求公共类型（该匿名类型的不是的），并且仅适用于读写成员（其中匿名类型的没有的）。 的DataContractSerializer 想要的属性（其匿名类型的没有的）。

坦率地说，最简单，最支持的固定在这里正式宣布POCO DTO匹配你是什么之后，又名：不使用匿名类型在这里。例如：

 公共类MyDto {
    公共字符串FOO {获取;集;}
}
...
VAR foobar的=新MyDto {FOO =酒吧};
 

另一种方法是的实际上的写自己的XML序列化。这......听起来并不很有趣。

Is there any possible way to serialize dynamically created object to an xml string?

var foobar = new { foo = "bar" };
string xml = ConvertToXMLString(foobar);
//xml should be something like : 
//<foo>bar</foo>

I was able to take a look at XMLSerializer and DataContractSerializer but XMLSerializer requires the object type while DataContractSerializer requires attribute on the properties that needs to be serialized.

Out of desperation, I converted the object to JSON first and from JSON converted it to XML.

var foobar = new { foo = "bar" };
JavaScriptSerializer js = new JavaScriptSerializer();
jsonString = js.Serialize(values);
//Json.NET at http://json.codeplex.com/
XmlDocument doc = (XmlDocument)JsonConvert.DeserializeXmlNode(jsonString);

解决方案

Not using the standard inbuilt serializers, no; XmlSerializer demands public types (which anonymous types aren't), and only works for read-write members (which anonymous types don't have). DataContractSerializer wants attributes (which anonymous types don't have).

Frankly, the simplest and most supportable "fix" here is to formally declare a POCO DTO that matches what you are after, aka: don't use an anonymous type here. For example:

public class MyDto {
    public string foo {get;set;}
}
...
var foobar = new MyDto { foo = "bar" };

The alternative would be essentially writing your own xml serializer. That... does not sound like fun.
