问题描述
[XmlRoot("A")]
public class Foos
{
[XmlElement("A1")]
public List<Foo> FooList{ get; set; }
}
var serializer = new XmlSerializer(typeof(Foos));
此代码也能正常工作.但它不是动态的.我想要 [XmlRoot("A")]
到 [XmlRoot(ConfigurationManager.AppSettings[someValue])]
.但是会抛出语法错误.然后我试试这个
This code working as well. But its not dynamic. I want [XmlRoot("A")]
to [XmlRoot(ConfigurationManager.AppSettings[someValue])]
. But is throw to syntax error. Then i try this
public class Foos
{
[XmlElement("A1")]
public List<Foo> FooList{ get; set; }
}
var serializer = new XmlSerializer(typeof(Foos),new XmlRootAttribute(ConfigurationManager.AppSettings[someValue]));
这只是根元素的工作.我正在工作.我无法动态更改 FooList 的XmlElement"值.类中可以有多个元素.如何动态更改所有这些的 XmlElement 值?
This is work just root element.I'm working. I could not change the "XmlElement" value of the FooList dynamically.There can be more than one element in the class. How do I change the XmlElement value of all of them dynamically?
推荐答案
您需要以正确的方式使用 XmlAttributesOverrides.请检查.
You need to use XmlAttributesOverrides in a right way. Please Check.
您的代码的工作版本在这里.
Working version of your code is here.
public class Foos
{
public List<Foo> FooList { get; set; }
}
public class Foo
{
public string Name { get; set; }
}
class Program
{
static void Main(string[] args)
{
var xmlAttributeForFoos = new XmlAttributes { XmlRoot = new XmlRootAttribute(ConfigurationManager.AppSettings["someFoosValue"]), XmlType = new XmlTypeAttribute(ConfigurationManager.AppSettings["someFoosValue"]) };
var xmlAttributeForFooList = new XmlAttributes();
var xmlAttributeForFoo = new XmlAttributes();
xmlAttributeForFooList.XmlElements.Add(new XmlElementAttribute(ConfigurationManager.AppSettings["someFooValue"]));
xmlAttributeForFoo.XmlElements.Add(new XmlElementAttribute(ConfigurationManager.AppSettings["someFooNameValue"]));
var overrides = new XmlAttributeOverrides();
overrides.Add(typeof(Foos), xmlAttributeForFoos);
overrides.Add(typeof(Foos), "FooList", xmlAttributeForFooList);
overrides.Add(typeof(Foo), "Name", xmlAttributeForFoo);
XmlSerializer serializer = new XmlSerializer(typeof(Foos), overrides);
var foos = new Foos
{
FooList = new List<Foo>
{
new Foo{Name = "FooName"}
}
};
using (var stream = File.Open("file.xml", FileMode.OpenOrCreate))
{
serializer.Serialize(stream, foos);
}
}
}
应用设置
<appSettings>
<add key="someFoosValue" value="SomeFoos"/>
<add key="someFooValue" value="SomeFoo"/>
<add key="someFooNameValue" value="FooName"/>
</appSettings>
输出
<SomeFoos xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<SomeFoo>
<FooName>FooName</FooName>
</SomeFoo>
</SomeFoos>
