自动生成类的反序列化

Question

I'm using binary serialization to save objects to a configuration file and read them back again. One of these classes has an event handler which I forgot to mark with the NonSerializedAttribute in previous builds, so this bit of information has already ended up in a few config files. To complicate matters, this handler is initialized with a lamda expression, which forces the compiler to automatically generate an anonymous type for it.

public event PropertyChangedEventHandler PropertyChanged = (sender, args) => { };

The issue is that this type name changed in subsequent builds, so when the BinaryFormatter encounters an unknown type, it throws a SerializationException ("Cannot find member: <.ctor>b__1"). I can't seem to catch this exception at the right location since it occurs deep inside mscorlib.dll , and I've had no luck with the SerializationBinder .

Is there any way I can force the BinaryFormatter to ignore this field, or remove it from the serialized stream entirely? I should add that this class in question does not implement the ISerializable interface.

也许我缺少了一些东西，但是您不能只用NonSerializedAttribute标记该字段吗？
