How to serialize object fields with NLog?

Im testing out the new structured logging but do not really get it right.

I have this in my nlog.config :

<target xsi:type="File" name="f" fileName="${basedir}/logs/${shortdate}.log"><layout xsi:type="JsonLayout" includeAllProperties="true">${longdate}|${level}|${logger}|${message}</layout></target><logger name="CommunicationLogger" minlevel="Info" writeto="f"></logger>

My log code looks like this :

public void LogCommunication(string operation, List<object> args)    {        var parameters = new List<object>();        var text = "Operation:{Operation} ";        parameters.Add(operation);        text += "PersonId:{PersonId} ";        parameters.Add(SharedContext.GetMyUserContext().CurrentPersonId);        text += "ClientMachineName:{ComputerName} ";        parameters.Add(SharedContext.GetMyUserContext().ClientMachineName);        text += "Servername:{MachineName} ";        parameters.Add(Environment.MachineName);        if (args != null)        {            foreach(var param in args)            {                text += "Param:{@Parameters} ";                parameters.Add(param);            }        }        _log.LogCommunication(text, parameters.ToArray());    }public void LogCommunication(string message, params object[] args)        {            _comLogger.Log(LogLevel.Info, message, args);        }

The output looks something like this :

{ "Operation": "OperationName", "PersonId": 1, "ComputerName":"MyComputername", "MachineName": "MyMachinename", "Parameters": {"LocationKeyList":[], "MyObjectIdList":[], "RolList":[]} }

I would like the Parameters to also get serialize instead of just showint [] so I can see all the parameters of the service operation. The parameter is a complex type with dataContract(WCF).

Is there a simple way to get the parameters to work with structural data.

Update1

nlog.config

<target xsi:type="File" name="f" fileName="${basedir}/logs/${shortdate}.log"><layout xsi:type="JsonLayout" includeAllProperties="true" maxRecursionLimit="10"><attribute name="time" layout="${longdate}" /><attribute name="level" layout="${level}"/><attribute name="message" layout="${message}" /></layout></target>

Code to setup data

var parameters = new List<object>();            var text = "{TimeStamp} - ";            parameters.Add(DateTime.Now);            text += "Duration:{Duration} ";            parameters.Add(Timestamp);            text += "Operation:{Operation} ";            parameters.Add(operation);            text += "PersonId:{PersonId} ";            parameters.Add(SharedContext.GetMyUserContext().CurrentPersonId);            text += "ClientMachineName:{ComputerName} ";            parameters.Add(SharedContext.GetMyUserContext().ClientMachineName);            text += "Servername:{MachineName} ";            parameters.Add(Environment.MachineName);            if (args != null && args.Count() > 0)            {                text += "Param:{@Parameters} ";                parameters.Add(args);            }            _log.LogCommunication(text, parameters.ToArray());

result :

ientMachineName:\"MyComputer\" Servername:\"MyComputer\" Param:[\"MyApp.ServiceContracts.GetEntityViewRequest\"] ","TimeStamp": "2020-04-08T23:30:59.7725147Z", "Duration":"00:00:00.0009930", "Operation": "GetReferenceData", "PersonId": 1,"ComputerName": "SE-MyCom", "MachineName": "SE-MyCom","Parameters": ["MyApp.ServiceContracts.GetEntityViewRequest"] }

{ "time": "2020-04-09 01:31:00.3637", "level": "Info", "message":"2020-04-09 01:31:00 - Duration:00:00:00.5594936 Operation:\"GetExternaAnrop\" PersonId:1 ClientMachineName:\"MyComputer\" Servername:\"MyComputer\" Param:[{\"PlaceringKeyList\":[], \"ArbetsstalleIdList\":[], \"RollList\":[]}] ", "TimeStamp": "2020-04-08T23:31:00.363752Z","Duration": "00:00:00.5594936", "Operation": "GetExternaAnrop","PersonId": 1, "ComputerName": "SE-MyCom", "MachineName":"SE-MyCom", "Parameters": [{"PlaceringKeyList":[],"ArbetsstalleIdList":[], "RollList":[]}] }

Update2

I have a service method that looks like this :

GetEntityViewResponse GetReferenceData(GetEntityViewRequest request);

The request class looks like this :

[DataContract]    public class GetEntityViewRequest    {        public GetEntityViewRequest(params EntityViewKey[] Keys)        {            EntityViewKeys.AddRange(Keys);        }        public GetEntityViewRequest(params int[] EgnaKodtyper)        {            MyList.AddRange(EgnaKodtyper);        }        public GetEntityViewRequest()        {        }        [DataMember]        public List<EntityViewKey> EntityViewKeys = new List<EntityViewKey>();        [DataMember]        public List<int> MyList= new List<int>();    }

When running the code(sending the request) I can see in my messageInspector on the serviceside that I got data. The EntityViewKeys have a enum set.

The NLog output looks like this :

{ "time": "2020-04-12 19:27:55.6690", "level": "Info", "message":"2020-04-12 19:27:55 - Duration:00:00:00.0034730 Operation:\"GetReferenceData\" PersonId:1 ClientMachineName:\"MyComputer\" Servername:\"MyComputer\" Param:[\"Orbit.ServiceContracts.GetEntityViewRequest\"] ","TimeStamp": "2020-04-12T17:27:55.6690745Z", "Duration":"00:00:00.0034730", "Operation": "GetReferenceData", "PersonId": 1,"ComputerName": "SE-MyCom", "MachineName": "SE-MyCom","Parameters": ["Orbit.ServiceContracts.GetEntityViewRequest"] }

So even if the class is not complex it is still not printing the content in NLog?
