本文介绍了一个基于Revit API的.NET实现，用于获取用户在Revit界面中选择的建筑元素，并显示所选元素的ID。此外，还提供了一个查询当前文档中所有门元素ID的功能。

start

[Transaction(TransactionMode.Manual)]
[Regeneration(RegenerationOption.Manual)]
public class Document_Selection : IExternalCommand
{
    public Result Execute(ExternalCommandData commandData, ref string messages, ElementSet elements)
    {
        try
        {
            UIDocument uidoc = commandData.Application.ActiveUIDocument;
            //得到选择的对象
            Selection selection = uidoc.Selection;
            ElementSet collection = selection.Elements;
            if (0 == collection.Size)
            {
                TaskDialog.Show("Revit", "You haven't selected any elements");
            }
            else
            {
                string info = "Ids of selected elements in the document are:";
                foreach (Element elem in collection)
                {
                    info += "\n\t" + elem.Id.IntegerValue;
                }
                TaskDialog.Show("Revit", info);
            }

            //得到当前文档中门的ID
            ElementClassFilter familyInstanceFilter = new ElementClassFilter(typeof(FamilyInstance));
            ElementCategoryFilter doorsCategoryfilter = new ElementCategoryFilter(BuiltInCategory.OST_Doors);
            LogicalAndFilter doorsInstancefilter = new LogicalAndFilter(familyInstanceFilter, doorsCategoryfilter);
            FilteredElementCollector collector = new FilteredElementCollector(uidoc.Document);
            ICollection<ElementId> doors = collector.WherePasses(doorsInstancefilter).ToElementIds();
            string prompt = "the ids of the doors in the current document are:";
            foreach (ElementId id in doors)
            {
                prompt += "\n\t" + id.IntegerValue;
            }
            TaskDialog.Show("Revit", prompt);
        }
        catch (Exception e)
        {
            messages = e.Message;
            return Result.Failed;
        }
        return Result.Succeeded;
    }
}

end
