The type Nino.Test.Editor.Serialization.AbstractClass does not have NinoSerialize attribute or custom importer/exporter

给这个类打个标签[NinoSerialize]

[526077247]

还有个问题，用了抽象类，生成出来的代码就有问题了

[JasonXuDeveloper]

ok，你先试试打个标签后能用不

[526077247]

打了标签后，报其他的错了。 MissingMethodException: Default constructor not found for type Nino.Test.Editor.Serialization.AbstractClass System.RuntimeType.CreateInstanceMono (System.Boolean nonPublic, System.Boolean wrapExceptions) (at <9aad1b3a47484d63ba2b3985692d80e9>:0) System.RuntimeType.CreateInstanceSlow (System.Boolean publicOnly, System.Boolean wrapExceptions, System.Boolean skipCheckThis, System.Boolean fillCache) (at <9aad1b3a47484d63ba2b3985692d80e9>:0) System.RuntimeType.CreateInstanceDefaultCtor (System.Boolean publicOnly, System.Boolean skipCheckThis, System.Boolean fillCache, System.Boolean wrapExceptions, System.Threading.StackCrawlMark& stackMark) (at <9aad1b3a47484d63ba2b3985692d80e9>:0) System.Activator.CreateInstance (System.Type type, System.Boolean nonPublic, System.Boolean wrapExceptions) (at <9aad1b3a47484d63ba2b3985692d80e9>:0) System.Activator.CreateInstance (System.Type type, System.Boolean nonPublic) (at <9aad1b3a47484d63ba2b3985692d80e9>:0) System.Activator.CreateInstance (System.Type type) (at <9aad1b3a47484d63ba2b3985692d80e9>:0) Nino.Serialization.Deserializer.Deserialize (System.Type type, System.Object val, System.Span1[T] data, Nino.Serialization.Reader reader, Nino.Serialization.CompressOption option, System.Boolean returnDispose) (at Assets/Nino/Serialization/Deserializer.cs:205) Nino.Serialization.Deserializer.Deserialize (System.Type type, System.Object val, System.Span1[T] data, Nino.Serialization.Reader reader, Nino.Serialization.CompressOption option, System.Boolean returnDispose) (at Assets/Nino/Serialization/Deserializer.cs:268) Nino.Serialization.Deserializer.Deserialize[T] (System.Span`1[T] data, Nino.Serialization.Reader reader, Nino.Serialization.CompressOption option, System.Boolean returnDispose) (at Assets/Nino/Serialization/Deserializer.cs:120) Nino.Serialization.Deserializer.Deserialize[T] (System.Byte[] data, Nino.Serialization.CompressOption option) (at Assets/Nino/Serialization/Deserializer.cs:48) Nino.Test.Editor.Serialization.Test12.Main () (at Assets/Nino/Test/Editor/Serialization/Test12.cs:41)

ok，我这几天去解决一下，目前可以根据UnitTest里的polymorphismTest写个多态代码

不打算支持抽象类了，因为会大幅度扩大Collection类型的体积
