Femap API Error "Type mismatch"

[vvk_187]

Hi, Where is the mistake?

 pNodeSet.AddAll(zDataType.FT_NODE);
            pNodeSet.Debug();

            int nodeCount = pNodeSet.Count();
            Console.WriteLine("nodeCount =" + nodeCount);
            Console.ReadKey();
            
            int nodeID;
            object XYZ;
            object wpXYZ;
            double[] outwpXYZ = new double[3];
            

            while (pNodeSet.Next()>0)
            {
                   nodeID = pNodeSet.CurrentID;
                   Console.WriteLine("nodeID =" + nodeID);
                   Console.ReadKey();
                    
                                    
                     pNode.Get(nodeID);
                     XYZ = pNode.xyz;
                    
                    
                    pModel.feCoordToWorkplane(XYZ, out wpXYZ);


                    outwpXYZ = (double[])wpXYZ;
                  
                  Console.WriteLine("nodeID=" + nodeID + " X=" + Math.Round(outwpXYZ[0], 2) + " Y=" + Math.Round(outwpXYZ[1], 2));
                  Console.ReadLine();
                

            }

i'm not too versed in the C API, only femap's native BASIC and the python API, but what line is giving you the type mismatch?

also it seems this is not the full code, but an excerpt

Thanks for the response.
This line gave an error
pModel.feCoordToWorkplane(XYZ, out wpXYZ);
Fixed everything by adding an object variable to the loop before the function and zeroing it.
object wpXYZ=null;
The question can be considered closed
