Hi,

I want to replace Part model in all the views of a drawing file,
I am using the below code:
 

            ModelDoc2 Drawingfile = (ModelDoc2)swApp_Active.GetOpenDocumentByName(NEW_FILE_PATH.Replace(".SLDPRT", ".SLDDRW"));
           if (Drawingfile == null)
               Drawingfile = swApp_Active.OpenDoc6(NEW_FILE_PATH.Replace(".SLDPRT", ".SLDDRW"), (int)swDocumentTypes_e.swDocDRAWING, (int)swOpenDocOptions_e.swOpenDocOptions_Silent, "", ref fileerror, ref filewarning);
           DrawingDoc swDrawing = (DrawingDoc)Drawingfile;
           bool success = false;
           try
           {
               ModelDocExtension swModelDocExt;
               SelectionMgr swSelectionMgr;
               DrawingComponent swDrawingComponent;
               View swView;
               Component2 swComponent;
               object view;
               object instance;
               object[] views = new object[swDrawing.GetViewCount()];
               object[] instances = new object[swDrawing.GetViewCount()];
               DispatchWrapper[] viewsIn = new DispatchWrapper[swDrawing.GetViewCount()];
               DispatchWrapper[] instancesIn = new DispatchWrapper[swDrawing.GetViewCount()];
               bool status;
               object[] All_Views = (object[])swDrawing.GetViews();
               IView[] Vviews = (IView[])All_Views;
               int v = 0;
               foreach (IView vv in Vviews)
               {
                   //View Curr_view = swDrawing.IActiveDrawingView();// GetView(i);
                   status = swDrawing.ActivateView(vv.Name);
                   //Select the view in which to replace the model
                   swModelDocExt = (ModelDocExtension)Drawingfile.Extension;
                   status = swModelDocExt.SelectByID2(vv.Name, "DRAWINGVIEW", 0, 0, 0, false, 0, null, 0);
                   swSelectionMgr = (SelectionMgr)Drawingfile.SelectionManager;
                   swView = (View)swSelectionMgr.GetSelectedObject6(1, -1);
                   view = (object)swView;
                   views[v] = view;
                   viewsIn[v] = new DispatchWrapper(views[v]);

                   // Select the instance of the model to replace
                   status = swModelDocExt.SelectByID2(vv.GetReferencedModelName(), "COMPONENT", 0, 0, 0, false, 0, null, 0);
                   swDrawingComponent = (DrawingComponent)swSelectionMgr.GetSelectedObject6(1, -1);
                   swComponent = (Component2)swDrawingComponent.Component;
                   instance = (object)swComponent;
                   instances[v] = instance;
                   instancesIn[v] = new DispatchWrapper(instances[v]);
                   v++;
               }
               success = swDrawing.ReplaceViewModel(NEW_FILE_PATH, (viewsIn), (instancesIn));
           }
           catch (Exception ex)
           {
               MessageBox.Show("Method 2 Error :" + ex.HResult);
               //throw;
           }

I am getting the below error:
Message = "Unable to cast object of type 'System.Object[]' to type 'SolidWorks.Interop.sldworks.IView[]'."

could anyone guide me how the rectify the above issue.
