Revit二次开发之“让对象处于被选择状态”

要想让对象被选择，需要知道对象的ID比如506025

uidoc.Selection.Elements.Add(element);

[Transaction(TransactionMode.Manual)]
[Regeneration(RegenerationOption.Manual)]
public class OpenDoc : IExternalCommand
{
    public Result Execute(ExternalCommandData commandData, ref string messages, ElementSet elements)
    {
        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);
        //}
        Element el = uidoc.Document.get_Element(new ElementId(506025));//得到对象
        SelElementSet selElements = uidoc.Selection.Elements;//添加到选择集里
        selElements.Add(el);

        return Result.Succeeded;
    }
}
