更改.Net中序列化的类的名称？

Question

我可以通过使用SerializationBinder和覆盖BindToType方法来映射传入的类名,但我发现无法在序列化过程中更改类的名称.有可能吗？

编辑:

我指的是使用的序列化System.Runtime.Serialization,而不是System.Xml.Serialization.

谢谢!

Answer 1

我不确定我是否关注你,但你可以使用XmlTypeAttribute.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;
}

看一下这个:

我发现我可以使用函数中的SerializationInfo对象GetObjectData,并更改AssemblyName和FullTypeName属性,这样当我反序列化时,我可以使用a SerializationBinder将自定义程序集和类型名称映射回有效类型.这是一个semple:

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:

public class MyBinder : SerializationBinder
{
    public override Type BindToType(string assemblyName, string typeName)
    {
        if (assemblyName == "MyCustomAssemblyIdentifier")
            if (typeName == "MyCustomTypeIdentifier")
                return typeof();
        return null;
    }
}

序列化代码:

var fs = GetStream();
BinaryFormatter f = new BinaryFormatter();
f.Binder = new MyBinder();
var obj = (MyCustomClass)f.Deserialize(fs);

反序列化代码:

var fs = GetStream();
MyCustomClass obj = GetObjectToSerialize();
BinaryFormatter f = new BinaryFormatter();
f.Deserialize(fs, obj);
