　　在ProE二次开发中，时常需要遍历ProSolid下的面、点、轴等几何元素。我们知道，ProToolkit下的遍历函数还是有点小麻烦的，而ProWebLink中就简单很多，比如要遍历某ProSolid下的所有Group，代码如下：

1 var  groupList = sld.ListGroups();2 for (var i=0; i

　　那么，ProToolkit下是否可以封装类似的代码呢？当然可以。

　　先贴一段我封装之后遍历访问ProSolid下所有Datum Point的代码：

1     ProError err; 2     ProMdl mdl_curr; 3     err = ProMdlCurrentGet(&mdl_curr); 4      5     try 6     { 7         // 利用当前Model构造CProSolid对象,并遍历访问其下的所有Datum Point 8         CProSolid sld((ProSolid)mdl_curr); 9         CProList
     
       pntList = sld.ListPoints();10         CString cstr;11         cstr.Format(TEXT("%d"), pntList.size());12         AfxMessageBox(cstr);13 14         // 对每个Datum Point执行操作15         for (int i=0; i

再贴上我封装的代码：

1、CProArray.h 在前一篇博文<<类似vector的ProArray封装类CProArray>>中已贴出。

2、CProList.h

使用及代码说明：

1、使用时请包含以下头文件即可：

#include "CProArray.h"

　　#include "CProList.h"

　　#include "CProSolid.h"

2、之所以可以向WebLink那样使用，关键是CProList类的封装，该类有一个CProArray类的指针，并且CProArray类中包含一个引用计数，表明当前有多少个CProList对象引用了CProArray对象，这样，CProList对象的直接赋值实际上并没有重新分配数组对象，仅仅是增加了引用的数组CProArray的引用计数。

3、CProList对象会自动释放申请的数组内存，当引用计数变为0时。所以，使用者无需自己释放数组内存。
