提取CAD图元所有属性字段，通过窗体显示，效果如下：

代码如下：

   public void 属性查询()       
   {
           List<Curve> ents = Z.db.SelectEntities<Curve>();
       if (ents is null ||ents.Count ==0)
       {
           Z.ed.WriteMessage("未选择!\n");
           return;
       }
       object obj = ents[0];
           string str = "";
           str += "对象全部属性:  >\n";
           str += "类型:    " + obj.GetType() + "\n";
           PropertyInfo[] pis = obj.GetType().GetProperties(BindingFlags.Public | BindingFlags.Instance);
           foreach (var pi in pis)
           {
               try { str += pi.Name + " :    " + pi.GetValue(obj, null).ToString() + "\n"; }
               catch { str += pi.Name + "     " + "Null" + "\n"; }
           }
           //MessageBox.Show(str);
           TextForm f = new TextForm();
           f.richTextBox1.Text = str;
           Autodesk.AutoCAD.ApplicationServices.Application.ShowModalDialog(f);
   }
