如果您只想删除名称空间 aliases ，那么如已显示的那样，您可以使用 XmlSerializerNamespaces 强制 XmlSerializer 在每个元素上显式使用名称空间 (即 xmlns ="blah" )，而不是声明别名并改用别名

If you just want to remove the namespace aliases, then as already shown you can use XmlSerializerNamespaces to force XmlSerializer to use the namespace explicitly (i.e. xmlns="blah") on each element, rather than declaring an alias and using the alias instead.

但是，无论您使用别名做什么，该元素的基本名称都是 Com.Foo.Request 名称空间中的 REQUEST_GROUP .您不能完全删除名称空间 ，除非该名称空间表示对基础数据的重大更改-即某个地方的某人将要获取异常(由于获取了意外的数据-特别是根名称空间中的REQUEST_GROUP ).用C#术语来说，这是 System.String 和 My.Custom.String 之间的区别-当然，它们都被称为 String ，但是只是他们的 local 名称.

However, regardless of what you do with the aliases, the fundamental name of that element is REQUEST_GROUP in the Com.Foo.Request namespace. You can't remove the namespace completely without that representing a breaking change to the underlying data - i.e. somebody somewhere is going to get an exception (due to getting data it didn't expect - specifically REQUEST_GROUP in the root namespace). In C# terms, it is the difference between System.String and My.Custom.String - sure, they are both called String, but that is just their local name.

如果您想要要删除名称空间的所有痕迹，那么务实的选择是从 [XmlRoot]中删除 Namespace = ... 条目(...)] 和 [XmlType(...)] (以及示例中未显示的其他任何地方).

If you want to remove all traces of the namespace, then a pragmatic option would be to edit away the Namespace=... entries from [XmlRoot(...)] and [XmlType(...)] (plus anywhere else that isn't shown in the example).

如果类型不在您的控制范围内，则还可以在运行时使用 XmlAttributeOverrides 进行操作-但要注意:如果使用 XmlAttributeOverrides创建 XmlSerializer 您 必须 缓存并重新使用它-否则您的 AppDomain 会泄漏(它会动态地 per序列化器(在这种模式下，程序集不能卸载).

If the types are outside of your control, you can also do this at runtime using XmlAttributeOverrides - but a caveat: if you create an XmlSerializer using XmlAttributeOverrides you must cache and re-use it - otherwise your AppDomain will leak (it creates assemblies on the fly per serializer in this mode, and assemblies cannot be unloaded).
