Topic: SurfaceOperationCollection sorting SurfaceOperationObjects

[cadplayer]

Hello!
I have read SurfaceOperationCollection from a Surface in a Drawing. This Surface have different types(or SurfaceOperations included). All these SurfaceOperation are in right sorting in Collection before I do somthing with Surface (for example remove or create new SurfaceOperations as breakline, contours or boundaries...). After editing I want same sorting in Surface as before.
In SurfaceOperation it haves different metods as MoveUp() or MoveDown(). Have somebody worked with them in Sytax of Linq. I´m very thankfully to get some suggestions

Maybe better description:
I have to remove a boundary in a Surface, and than recreate them and set the same name as before. The position of recreated boundary is in the end of SurfacOperationCollection. But it have to come in position 2 (for example)

Code: [Select]

        public static SurfaceOperationCollection ReadSurfaceOperations(TinSurface tinsurf)
        {
            Document acadDoc = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument;

            using (Transaction tr = acadDoc.TransactionManager.StartTransaction())
            {
                SurfaceOperationCollection SuOpColl = tinsurf.Operations;
                tr.Commit();

                return SuOpColl;
            }
        }

        public static void SortSurfaceOperations(SurfaceOperationCollection before, SurfaceOperationCollection after)
        {
            Document acadDoc = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument;

            using (Transaction tr = acadDoc.TransactionManager.StartTransaction())
            {
                var m_Bef = from x in before.GetType().FullName
                            //where x.GetType().FullName == "Autodesk.Civil.DatabaseServices.SurfaceOperationAddBoundary"
                            select x;

                var m_Aft = from x in before.GetType().FullName
                            //where x.GetType().FullName == "Autodesk.Civil.DatabaseServices.SurfaceOperationAddBoundary"
                            select x;

                foreach(SurfaceOperation x in m_Bef)
                {
                    foreach(SurfaceOperation y in m_Aft)
                    {
                        if(x != y)
                        {
                            y.MoveUp();
                        }
                    }
                }

                tr.Commit();
            }
        }

Dirk, you cannot use Linq with the SurfaceOperationCollection as it does not have a GetEnumerator() method. Just as you cannot use foreach() with this collection. Therefor you have to use a for() loop. The following code is not tested, but should work (or be close to working, anyway).

Code - C#: [Select]

1.         public static void SortSurfaceOperations(SurfaceOperationCollection before, SurfaceOperationCollection after)
2.         {
3.             Document acadDoc = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument;
4.             using (Transaction tr = acadDoc.TransactionManager.StartTransaction())
5.             {
6.                 bool done = false;
7.                 for (int i = 0; i < before.Count;i++ )
8.                 {
9.                     var x = before[i];
10.                     if (x.GetType() == typeof(SurfaceOperationAddBoundary))
11.                     {
12.                         for (int j = 0; j < after.Count; j++)
13.                         {
14.                             var y = after[j];
15.                             if (y.GetType() == typeof(SurfaceOperationAddBoundary))
16.                             {
17.                                 while (i < j)
18.                                 {
19.                                     y.MoveUp();
20.                                     j--;
21.                                 }
22.                                 done = true;
23.                                 break;
24.                             }
25.                         }
26.                     }
27.                     if (done)
28.                         break;
29.                 }
30.                 tr.Commit();
31.             }
32.         }
33.
