Topic: Attribute tag C#

[MP]

Thanks Bobby and Thorsten for these nice examples.

Ditto that.

I was off topic with my F# code

Are you lost? This is the swamp. Off topic IS on topic. Please continue to post your most valued code + comments my friend.

Thank you for all the replies. I hope to have time today to look at it all. Thanks again.

Another way using Linq extension methods

Code: [Select]

        public ObjectId[] SelByTag(string tag)
        {
            Document doc = AcAp.DocumentManager.MdiActiveDocument;
            Database db = doc.Database;
            Editor ed = doc.Editor;
            tag = tag.ToUpper();
            TypedValue[] filter = new TypedValue[2] { new TypedValue(0, "INSERT"), new TypedValue(66, 1) };
            PromptSelectionResult psr = ed.GetSelection(new SelectionFilter(filter));
            if (psr.Status != PromptStatus.OK) return null;
            using (Transaction tr = db.TransactionManager.StartTransaction())
            {
                return psr
                    .Value
                    .GetObjectIds()
                    .Where(brId => ((BlockReference)tr.GetObject(brId, OpenMode.ForRead))
                        .AttributeCollection
                        .Cast<ObjectId>()
                        .Any(attId => ((AttributeReference)tr.GetObject(attId, OpenMode.ForRead))
                            .Tag == tag))
                    .ToArray();
            }
        }
