拾取点时出现的问题

请教斑竹在点取坐标的时候怎样用一个循环语句可以一直点取直到确定为止，显示在命令行里？

仔细看下这两天的帖子，有这方面的代码：

        [CommandMethod("t2")]
        public static void Test2()
        {
            Document doc = Application.DocumentManager.MdiActiveDocument;
            Database db = doc.Database;
            Editor ed = doc.Editor;
            var optPt = new PromptPointOptions("\n选择第一点");
            optPt.AllowNone = true;
            var resPt = ed.GetPoint(optPt);
            optPt.Message = "\n选择下一点";
            optPt.UseBasePoint = true;
            while (resPt.Status == PromptStatus.OK)
            {
                optPt.BasePoint = resPt.Value;
                resPt = ed.GetPoint(optPt);
            }
        }

飞狐大哥下面这段代码加个循环，该怎么编？先谢谢了
[CommandMethod("PP")]
public void Pickpt()
      {
         Editor ed = Application.DocumentManager.MdiActiveDocument.Editor;
         Point3d pt = Pick("\n 拾取点");
         ed.WriteMessage("\n{0:f1}", pt);
      }
   public static Point3d Pick(string word)
   {
      Document doc = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument;
      Editor ed = doc.Editor;
      PromptPointResult pt = ed.GetPoint(word);
      if (pt.Status == PromptStatus.OK)
      {
            return (Point3d)pt.Value;
      }
      else
      {
            return new Point3d();
      }
   }

}
希望会对你有用。
