Explode within pre-selected coordinates via doc.Editor.Command ?

[h3nrik]

Hi

I have this piece of code that works , values[0] and [1] are like 400,200 500,0 that are read from a text-file. So the script can go in and erase one time or eight times at different locations depending on data in text-file

ed = Application.DocumentManager.MdiActiveDocument.Editor;
ed.Command("ERASE, "CROSS", values[0].Trim(), values[1].Trim(), "");

Now I want to explode also, and thought I could just do

ed.Command("EXPLODE", "CROSS", values[0].Trim(), values[1].Trim(), "");

But it doesn't work at all, I get this output in the command window. But if I type out the commands manually it works fine..

Select object: 4000,2000
None found.
Select object: 0,0

Googling around all example I find is about exploading blocks with certain names or based on user selection, none which will work for me.

What am I doing wrong and what are my options?

Edit1:
Full method that I use to test, with static coordinates

 [CommandMethod("valitExplodeTest")]
        public static void ExplodeTest() {
            var doc = Application.DocumentManager.MdiActiveDocument;
            Editor ed = Application.DocumentManager.MdiActiveDocument.Editor;
            try {
                doc.Editor.ZoomExtents();
                ed.Command("EXPLODE", "4000,2000","0,0", "");
            } catch (Autodesk.AutoCAD.Runtime.Exception e) {
                ed.WriteMessage(e.Message);
            }
        }

Edit2:

I tried to change the command to some variants, and tried just this

ed.Command("EXPLODE");

Which starts the EXPLODE command but I cannot select coordinates as I can if I type in EXPLODE myself, so comparing the arguments that EXPLODE is expecting:
Manual: Expects a point or Window/Last/Crossing/BOX/ALL/Fence/WPolygon/CPolygon/Group/Add/Remove/Multiple/Previous/Undo/AUto/SIngle
From DLL: Expects a point or Last/ALL/Group

Both at least have point..and both have ALL. So I tried all

ed.Command("EXPLODE", "ALL","");

The object is not able to be exploded.

So it cannot explode anything...
Do I need to open some transaction or BlockTable or something before running explode? Ideas?

After a good night sleep and more searching I found this post, https://forums.autodesk.com/t5/net/explode-command-by-c/td-p/9774112
Which was quite close and after copy-paste-glue I got something that looks like it is working just fine

Document document = Application.DocumentManager.MdiActiveDocument;
            Editor editor = Application.DocumentManager.MdiActiveDocument.Editor;
            
            using (Transaction transaction = document.Database.TransactionManager.StartTransaction()) {
                try {
                    BlockTable blockTable = transaction.GetObject(document.Database.BlockTableId, OpenMode.ForRead) as BlockTable;
                    BlockTableRecord blockTableRecord = transaction.GetObject(blockTable[BlockTableRecord.ModelSpace], OpenMode.ForWrite) as BlockTableRecord;

                    PromptSelectionResult selectionResult = editor.SelectCrossingWindow(new Point3d(4000, 2000,0), new Point3d(0, 0, 0));
                    if (selectionResult.Status == PromptStatus.OK) {
                        foreach (ObjectId objectId in selectionResult.Value.GetObjectIds()) {
                            Entity entity = transaction.GetObject(objectId, OpenMode.ForRead) as Entity;
                            using (DBObjectCollection objectCollection = new DBObjectCollection()) {
                                entity.Explode(objectCollection);

                                foreach (DBObject obj in objectCollection) {
                                    Entity explodedEntity = obj as Entity;
                                    blockTableRecord.AppendEntity(explodedEntity);
                                    transaction.AddNewlyCreatedDBObject(explodedEntity, true);
                                }
                                if (objectCollection.Count > 0) {
                                    entity.UpgradeOpen();
                                    entity.Erase(true);
                                }
                            }
                        }
                    }
                    transaction.Commit();
                } catch (Autodesk.AutoCAD.Runtime.Exception ex) {
                    editor.WriteMessage("\nError " + ex.Message);
                    transaction.Abort();
                }
            }
