[英]Change the name of the class being serialized in .Net?
I can map incoming class names by using a SerializationBinder
and overriding the BindToType
method, but I found no way of changing the name of the class in the serialization process. 我可以使用SerializationBinder
映射传入的类名并覆盖BindToType
方法,但我发现无法在序列化过程中更改类的名称。 Is it possible at all?? 有可能吗?
EDIT: 编辑:
I am referring to the serialization using the System.Runtime.Serialization
, and not the System.Xml.Serialization
. 我指的是使用System.Runtime.Serialization
的序列化,而不是System.Xml.Serialization
。
Thanks! 谢谢!
I'm not sure if I follow you, but you could use XmlTypeAttribute. 我不确定我是否关注你,但你可以使用XmlTypeAttribute。 You can then easily retrieve its values through reflection. 然后,您可以通过反射轻松检索其值。
[XmlType(Namespace = "myNamespaceThatWontChange",
TypeName = "myClassThatWontChange")]
public class Person
{
public string Name;
}
Check this out: 看一下这个:

I found out that I can use the SerializationInfo
object that comes in the GetObjectData
function, and change the AssemblyName
and FullTypeName
properties, so that when I deserialize I can use a SerializationBinder
to map the custom assembly and type-name back to a valid type. 我发现我可以使用GetObjectData
函数中的SerializationInfo
对象,并更改AssemblyName
和FullTypeName
属性,这样当我反SerializationBinder
,我可以使用SerializationBinder
将自定义程序集和类型名称映射回有效类型。 Here is a semple: 这是一个semple:
Serializable class: 可序列化类:
[Serializable]
class MyCustomClass : ISerializable
{
string _field;
void MyCustomClass(SerializationInfo info, StreamingContext context)
{
this._field = info.GetString("PropertyName");
}
void ISerializable.GetObjectData(SerializationInfo info, StreamingContext context)
{
info.AssemblyName = "MyCustomAssemblyIdentifier";
info.FullTypeName = "MyCustomTypeIdentifier";
info.AddValue("PropertyName", this._field);
}
}
SerializationBinder: SerializationBinder:
public class MyBinder : SerializationBinder
{
public override Type BindToType(string assemblyName, string typeName)
{
if (assemblyName == "MyCustomAssemblyIdentifier")
if (typeName == "MyCustomTypeIdentifier")
return typeof();
return null;
}
}
Serialization code: 序列化代码:
var fs = GetStream();
BinaryFormatter f = new BinaryFormatter();
f.Binder = new MyBinder();
var obj = (MyCustomClass)f.Deserialize(fs);
Deserialization code: 反序列化代码:
var fs = GetStream();
MyCustomClass obj = GetObjectToSerialize();
BinaryFormatter f = new BinaryFormatter();
f.Deserialize(fs, obj);
You can do it with attributes: 你可以用属性来做:
[System.Xml.Serialization.XmlRoot("xmlName")]
public Class ClassName
{
}
Look at using a surrogate + surrogate selector. 看看使用代理+代理选择器。 That together with a binder on the deserialization should do the trick. 这与反序列化的绑定一起应该可以解决问题。
