XML Serialization and null value - C#
提问by DotnetDude
I have an object that I serialize to XML. If one of the properties in the object is null, then native serialization ignores to add this as the attribute. Is this normal behavior, if so, is there a way I can override it?
我有一个序列化为 XML 的对象。如果对象中的属性之一为空，则本机序列化会忽略将其添加为属性。这是正常行为吗，如果是这样，有没有办法覆盖它？
ex:
前任：
public class Test
{
[XmlAttribute]
public string value {set; get; }
[XmlAttribute]
public string key {set; get; }
}
When value is null, i get
当值为空时，我得到
<Root>
<Test key="blah">
</Root>

In case Sunny's answer just doesn't fits to you, you can customize the serialization process by implementing the IXmlSerializable interface
如果 Sunny 的回答不适合您，您可以通过实现 IXmlSerializable 接口来自定义序列化过程
