How do you use XMLSerialize for Enum typed properties in c#?
提问by Rhubarb
I have a simple enum:
我有一个简单的枚举：
enum simple
{
one,
two,
three
};
I also have a class that has a property of type simple. I tried decorating it with the attribute: [XmlAttribute(DataType = "int")]. However, it fails when I try to serialize it using an XmlWriter.
我还有一个具有 type 属性的类simple。我尝试用属性装饰它：[XmlAttribute(DataType = "int")]。但是，当我尝试使用XmlWriter.
What is the proper way to do this? Do I have to mark the enum itself as well as the property, and if so, with which data type?
这样做的正确方法是什么？我是否必须标记枚举本身以及属性，如果是，使用哪种数据类型？

There shouldn't be any problems serializing enum properties:
序列化枚举属性应该没有任何问题：
public enum Simple { one, two, three }
public class Foo
{
public Simple Simple { get; set; }
}
class Program
{
static void Main(string[] args)
{
using (var writer = XmlWriter.Create(Console.OpenStandardOutput()))
{
var foo = new Foo
{
Simple = Simple.three
};
var serializer = new XmlSerializer(foo.GetType());
serializer.Serialize(writer, foo);
}
}
}
produces:
产生：
<?xml version="1.0" encoding="utf-8"?>
<Foo xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<Simple>three</Simple>
</Foo>

As per Darin Dimitrov's answer - only extra thing I'd point out is that if you want control over how your enum fields are serialized out then you can decorate each field with the XmlEnumattribute.
根据 Darin Dimitrov 的回答 - 我要指出的唯一额外的事情是，如果您想控制枚举字段的序列化方式，那么您可以使用XmlEnum属性装饰每个字段。
public enum Simple
{
[XmlEnum(Name="First")]
one,
[XmlEnum(Name="Second")]
two,
[XmlEnum(Name="Third")]
three,
}
