所谓遍历目录，就是给定一个目录，访问其中的所有文件(包括子目录下的文件)。迭代是比较常用的遍历算法。本文利用C++面向对象的特性，通过一个类CBrowseDir，对目录遍历进行了封装。用户只需掌握该类四个成员函数的用法，就可以在自己的程序中，很方便地实现目录遍历。

-called directory traversal is given a directory, which visited all documents (including subdirectories under). Iterative is the commonest traversal algorithm. By using object-oriented C Properties, a category CBrowseDir to directory traversal of Packaging. Users only need to master these four members of the usage function, it can own procedures, it is convenient to directory traversal.
