revit二次开发的问题

[hdztroop]

初学revit二次开发，下面一段代码，生成无错，执行无反应，是代码的问题吗？ using System; using Autodesk.Revit.DB; using Autodesk.Revit.UI; using Autodesk.Revit.Attributes; namespace HelloRevit { [Transaction(TransactionMode.Manual)] public class Class1 : IExternalCommand { public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elements) { UIApplication revit = commandData.Application; ElementSet collection = new ElementSet(); ElementSet selWall = new ElementSet(); foreach (ElementId elementId in revit.ActiveUIDocument.Selection.GetElementIds()) { collection.Insert(revit.ActiveUIDocument.Document.GetElement(elementId)); foreach (Element ele in collection) { Wall wall = ele as Wall; if (wall !=null) { selWall.Insert(ele); } } } return Result.Succeeded; } } }

感觉只是写了一个类，没有执行吧
