我开始了一个小项目，用统一的方式测试protobuf功能。 我试图从不同的按钮序列化序列化一些多态值。当我启动项目时，我总是在按钮单击时出现InvalidProgramException。但所有后续点击都不会导致异常。
我试图谷歌，但一无所获。
完整错误语法为：
InvalidProgramException: Invalid IL code in (wrapper dynamic-method) object:proto_3 (object,ProtoBuf.ProtoWriter): IL_0025: box 0x00000007
这是我用于的一些代码：
[ProtoContract(SkipConstructor = true)]
public struct NetworkCommandSerializationWrapper
{
[ProtoMember(1)]
public IActorNetworkCommand Command;
}
[ProtoContract]
[ProtoInclude(10, typeof(RendererStateNetworkCommand))]
[ProtoInclude(20, typeof(RD2))]
public interface IActorNetworkCommand
{
void Execute();
}
[ProtoContract]
public struct RendererStateNetworkCommand : IActorNetworkCommand
{
public RendererStateNetworkCommand(RendererStateNetworkData i)
{
data = i;
}
public void Execute()
{
}
[ProtoMember(11)]
public RendererStateNetworkData data;
}
public struct RD2 : IActorNetworkCommand
{
public void Execute()
{
}
[ProtoMember(21)]
public int data3;
}
public interface ISerializator<TResult>
{
TResult SerializeObject<T>(T serializableObject);
T DeserializeObject<T>(TResult serilizedBytes);
}
public class BinarySerializator : ISerializator<byte[]>
{
public byte[] SerializeObject<T>(T serializableObject)
{
Debug.LogFormat("SerializeObject {0}, {1}", serializableObject, serializableObject.GetType());
using (MemoryStream mStream = new MemoryStream())
{
Serializer.Serialize<T>(mStream, serializableObject);
return mStream.ToArray();
}
}
public T DeserializeObject<T>(byte[] serilizedBytes)
{
using (MemoryStream mStream = new MemoryStream(serilizedBytes))
{
return Serializer.Deserialize<T>(mStream);
}
}
}
public abstract class ButtonContextBase : MonoBehaviour, IButtonContext
{
public virtual void OnButtonClick()
{
ClickHandler.Instance.OnClick(SerializeData(GetCommand()));
}
protected abstract IActorNetworkCommand GetCommand();
protected byte[] SerializeData(IActorNetworkCommand command)
{
if (command == null)
{
Debug.LogErrorFormat("Command is null!");
return null;
}
var wrapper = new NetworkCommandSerializationWrapper() { Command = command };
Debug.LogFormat("SerializeData {0}, {1}", command, wrapper.Command);
var data = SerializatorSingletone.Instance.SerializeObject(wrapper);
return data;
}
}
public class RendererStateContext : ButtonContextBase
{
protected override IActorNetworkCommand GetCommand()
{
var command = new RendererStateNetworkCommand() { data = new RendererStateNetworkData() { sh_State = (ushort)ERendererState.Idle } };
return command;
}
}
public class SerializatorSingletone : MonoBehaviour
{
private static BinarySerializator m_Instance;
public static BinarySerializator Instance
{
get
{
if (m_Instance == null)
{
m_Instance = new BinarySerializator();
}
return m_Instance;
}
}
}
