[C# MSCE]参数话单元获得itemtype 变量 以及获得 变化值

请参考如下代码，其中的ParameterSet就是变化（Variation）值。

public static void PCParams(string unparsed)
        {
            string pcName = (unparsed == "") ? "Double Door Cabinet" : unparsed;
            var dgnFile = Session.Instance.GetActiveDgnFile();
            var pcDef = ParametricCellDefinitionElement.FindByName(pcName, dgnFile);
            if (null == pcDef)  //Not find cell def in active design file
            {
                var cellModel = CreateElements.LocateCellModel(pcName);
                if (null == cellModel)
                {
                    MessageCenter.Instance.ShowErrorMessage("Not found cell", null, true);
                    return;
                }
                var hdlr = DgnComponentDefinitionHandler.GetForModel(cellModel);
                var status = hdlr.DefinitionModelHandler.CreateCellDefinition(dgnFile);
                if (ParameterStatus.Success == status)
                    pcDef = ParametricCellDefinitionElement.FindByName(pcName, dgnFile);
                else
                {
                    MessageCenter.Instance.ShowErrorMessage("Error Creating cellDef", null, true);
                    return;
                }
            }
            string msg = "[" + pcName + "] includes below Variations:\n";
            foreach (ParameterSet ps in pcDef.ParameterSets)
            {
                msg += ps.Name + "\n";
            }
            MessageCenter.Instance.ShowInfoMessage(msg, null, true);

            msg = "[" + pcName + "] includes below ParameterDefinitions:\n";
            foreach (ParameterDefinition pd in pcDef.ParameterDefinitions)
            {
                if (!pd.IsHidden)
                    msg += "AccessString=" + pd.AccessString + ", DispalyLabel=" + pd.DisplayLabel + "\n";
            }
            MessageCenter.Instance.ShowInfoMessage(msg, null, true);

            msg = "[" + pcName + "] includes below Parameters:\n";
            foreach (var p in pcDef.Parameters)
            {
                msg += "AccessString=" + p.AccessString + ", Value=" + p.StringValue + "\n";
            }
            MessageCenter.Instance.ShowInfoMessage(msg, null, true);
        }

LocateCellModel函数如下：

public static DgnModel LocateCellModel(string name)
        {
            var opts = CellLibraryOptions.Include3d | CellLibraryOptions.IncludeAllLibraries | CellLibraryOptions.IncludeParametric;
            var libs = new CellLibraryCollection(opts);
            DgnModel cellModel = null;
            foreach (var lib in libs)
            {
                MessageCenter.Instance.ShowInfoMessage(lib.Name, lib.Name, false);
                if (name.Equals(lib.Name))
                {
                    StatusInt status;
                    cellModel = lib.File.LoadRootModelById(out status, lib.File.FindModelIdByName(lib.Name), true, false, true);
                    break;
                }
            }
            return cellModel;
        }

符老师    能得到单位么获得值的时候   我没得到单位  Parameters   dump   也没看到单位  

这个帖子中的C++代码含有如下三行关键代码，能获得属性的值和单位，就和我们从Property对话框中看到的一模一样。

https://communities.bentley.com/communities/other_communities/chinafirst/f/microstation-projectwise/195388/msce-c

IDgnECTypeAdapterR typeAdapter = IDgnECTypeAdapter::GetForProperty(*ecProp);
IDgnECTypeAdapterContextPtr typeContext = IDgnECTypeAdapterContext::Create(*ecProp, *elemInst, ecProp->GetName().GetWCharCP());
			typeAdapter.ConvertToString(valStr, ecVal, *typeContext);

C# 中没有找到对应的方法。

符老师    找了好久没找到  C#  IDgnECInstance怎么转C++ DgnECInstancePtr   找到一个Bentley.DgnPlatformNET.DgnEC.DgnECManager.Manager.ConvertManagedInstanceToNative   没转成 intptr

求指教
