MOSS基于AD的用户组织目录树选择工具的解决方案

本文的需求来自进来SharePoint开发中的人员选择，基础中国的用户更加喜欢通过组织结构来选择人员，这样可以清晰的知道选择人员的部门，通过组织结构选择人员是本文的讨论点。

我也是集合了前人的思路，进行了整合，参考了下面的博客

使用C＃中的DirectorySearcher来获得活动目录中的组织结构与用户等信息，并在展示成树形结构(附源代码)

感谢三位作者的无私奉献，为我的这篇博客提供了资料。

我的整个实现是由三个页面组成，首先是一个信息填写页面WebForm1.aspx，有一栏为选择任务的执行人员

这个东西本来是SharePoint开发过程中出来的需求，可是返回的只是一个组合了用户姓名的字符串，不能变成SPUser对象，SPUser对象又没有构造函数，有没有研究过这个呢，如果有的话，可以给我留言，谢谢了。
