Revit二次开辟根据ElementId一键删除Element

public void DelElementByIds(List delIds)
{
    Selection selection = _uiApp.ActiveUIDocument.Selection;
    selection.SetElementIds(delIds);//选中要删除Element
    RevitCommandId commandId = RevitCommandId.LookupPostableCommandId(PostableCommand.Delete);
    _uiApp.ActiveUIDocument.Application.PostCommand(commandId);//使用PostableCommand进行删除
}

之前我是循环一个一个删，效率太低了，用PostableCommand就非常快。
