How to get the result code after calling a method.|OPC UA Standard|Forum|OPC Foundation

Hi,

I am trying to call a method without of output parameter.

This is how i created the method on server side:

 #region Input Method

                    MethodState ReceiveMessageMethod = CreateMethod(root, “ReceiveMessage”, “ReceiveMessage”);

                    // set input arguments

                    ReceiveMsiMethod.InputArguments = new PropertyState<Argument[]>(ReceiveMsiMethod);

                    ReceiveMsiMethod.InputArguments.NodeId = new NodeId(ReceiveMsiMethod.BrowseName.Name + “InArgs”, NamespaceIndex);

                    ReceiveMsiMethod.InputArguments.BrowseName = BrowseNames.InputArguments;

                    ReceiveMsiMethod.InputArguments.DisplayName = ReceiveMsiMethod.InputArguments.BrowseName.Name;

                    ReceiveMsiMethod.InputArguments.TypeDefinitionId = VariableTypeIds.PropertyType;

                    ReceiveMsiMethod.InputArguments.ReferenceTypeId = ReferenceTypeIds.HasProperty;

                    ReceiveMsiMethod.InputArguments.DataType = DataTypeIds.String;

                    ReceiveMsiMethod.InputArguments.ValueRank = ValueRanks.OneDimension;

 

ReceiveMsiMethod.InputArguments.Value = new Argument[]

                    {

                        new Argument() { Name = “String value”, Description = “String value”,  DataType = DataTypeIds.String, ValueRank = ValueRanks.Scalar }

                    };

 

ReceiveMessageMethod.OnCallMethod = new GenericMethodCalledEventHandler(OnInputCall);

and the default OnInputCall method from foundation’s SDK:

        private ServiceResult OnInputCall(

            ISystemContext context,

            MethodState method,

            IList<object> inputArguments,

            IList<object> outputArguments)

        {

 

            // all arguments must be provided.

            if (inputArguments.Count < 1)

            {

                return StatusCodes.BadArgumentsMissing;

            }

 

            return ServiceResult.Good;

        }

This is how I call this method on client side:

IList<object> val = session.Call(new NodeId(“ns=2;s=Root”), new NodeId(“ns=2;s=ReceiveMessage”), “Test string”);

The problem now, is that I want to know if the call was successful or not. On client side, how can I get the ServiceResult from server?
