Problem with Exception types

[hammett]

Create or Pack with a class that has a reference to System.Exception will cause the following:

Unhandled Exception: System.Runtime.Serialization.SerializationException: Member
'HResult' is read only and its elementType ('System.Int32') is not an appendabl
e collection

Hi hammett. Thank you for your detailed reporting!

Unfortunately, MsgPack for CLI does not support to (de)serialize Exception because it is difficult to do perfectly. Could you use alternative class which stores information you want (such as type, message, stacktrace string).

Btw, I am very interested in why you want to serialize Exception.
Would you tell me why did you try to do?

Nevermind. We switched to protobuff.

We are using it to remote calls using 0mq. We do need to serialize exception information.

Thx
