No serializer defined for type: System.Management.Automation.PSObject in Protobuf-net

问题

this is my class

  [ProtoContract]
            internal class Powershellresults
            {
                internal Powershellresults()
                {
                }
                [ProtoMember(1)]
                public Collection<PSObject> PsObjects { get; set; }
                [ProtoMember(2)]
                public string Script { get; set; }
                [ProtoMember(3)]
                public string Viewname { get; set; }
            }

but i get No serializer defined for type: System.Management.Automation.PSObject when i try to serialize it

private byte[] SerializeResults(Powershellresults obj)
        {
            byte[] data;
            using (var ms = new MemoryStream())
            {
                ProtoBuf.Serializer.Serialize(ms, obj);
                data = ms.ToArray(); ;
            }
            return data;
        }

PsObject is part of System.Management.Automation

Can i get around this and actually serialize this collection?

UPDATE: by adding to my serialization method

RuntimeTypeModel.Default.Add(typeof(PSObject), true);

I can get it to serialize- but it loses most of it's fields once serialized how do i get it to "clone" the original object so it keeps all of its fields and properties?

EDIT

I figured it out! I thought to myself that Powershell had to be able to serialize it's objects, because you can poll remote machines - how else would it be able to send the PSObject between machines - which it does! (woohoo!!!!)

Well, i found an article that described this, and found my keyword System.Management.Automation.PSSerializer

Collection<PSObject> PSCol = Powershell.Invoke(); 
string SerializedCollection = PSSerializer.Serialize(PSCol);

//serialization to XML done!

then Serialize the string using Protobuf-net or what ever...

Deserialization is a bit awkward but pretty straight forward for deserialization use: Use Protobuf to deserialize the string and then...

PSObject obj = PSSerializer.Deserialize(DeserializedString) as PSObject;

Collection<PSObject> DeserializedCollection = new Collection<PSObject>(((ArrayList)obj.ImmediateBaseObject).Cast<PSObject>().ToArray());

and thats it..

回答2:

PSObject is too vague to make a good serialization candidate (not least, it is a dynamic provider, etc); I strongly recommend that you construct a well defined DTO model, i.e.

[ProtoMember(1)]
public Collection<SomeTypeThatYouOwn> Items {get;set;}

where SomeTypeThatYouOwn has meaningful properties etc. You can always convert to/from SomeTypeThatYouOwn close to the serialize/deserialize setp. PSObject is basically a property-bag, and that doesn't work well since protobuf doesn't include any metadata (you need to know the shape of the data in advance to deserialize it meaningfully).
