Question

Point3d[] 3dpoints = new Point3d[] { new Point3d(58, -4, 0), new Point3d(60, -4, 0), new Point3d(60, 98, 0), new Point3d(58, 98, 0), new Point3d(58, -4, 0)};     How to  add item to the above array

Hi Deepika,   Try this code,   public   class  Point   {   public   int  x{ get ; set ;}   public   int  y{ get ; set ;}   public   int  z{ get ; set ;}   }      main()   {   List  pointList= new  List ();   pointList.add(   new  Point   {   x=58,   y=-4,   z=0   });   pointList.add(   new  Point   {   x=60,   y=-4,   z=0   });   }

Hi,   If you want to add the item, add initialization itself  Point3d[] dpoints = new Point3d[] { new Point3d(58, -4, 0), new Point3d(51, -2, 0), new Point3d(53, -3, 0), new Point3d(54, -7, 0), new Point3d(56, -1, 0), new Point3d(56, -9, 0)   };   we can't add the item as seprately. Once above code execute the dpoint array variable size(Length) is set. After, you can't add item like below code.   dpoints[dpoints.Length] = new Point3d(55,6,2);
