取出AD中一個組的所有成員信息（C#實現功能配合EXT做的界面）

功能說明：

通過組名稱（AD組），取出用戶列表和用戶信息，如賬號、用戶名稱、說明、部門、職位、郵箱、OU等等AD賬號中已維護的信息。用EXT做的界面，可以導入多種格式的文件，當然用戶只是要Exsl格式就好。

先上效果圖:

1. 手工指定多個組名

2. 從列出的組名中選取、導出文件

需求背景：

之前开放的一个公共盘，一有职员需要，就申请开通权限，时间长了，人员的进进出出换了好多。有的部门管理人员也换了。出于一些原因，某天经理和yao的邮件

经理：please send the user access right for K drive to me 。

yao：是每一个用户的话，只好手工一个一个用户名列出，给一些时间才行。

经理：多做一点事情，我需要每个群组里的用户。

        堂文，可否写一个小系统，通过系统方法查询出来？以后可能常要拿这些信息。（这里开始邮件有抄送给我。）

yao:很多群组下面还包括群组，是否也要列出,我导出的只有登录帐号，没有名称。

经理:也需要，因为这个清单会交给他们自己做review，哪些权限需要调整，所以只给群组的名称，别人也看不懂是什么。

我:我可以測試一下看看，道理上是可以的。另外，P盤是否也要做控制？本來只是放WSD的數據的，現在什麼東西都有.

yao：现在我只能导出帐号名，没有其他信息，如果要全名那就要一个个在AD上对了。

        文，有没测试是否可以拿到我列出组的成员全名。

我：昨晚我已測試過，可以一個組一個組來列出組下邊的所有成員，成員的應有的信息都可以取到，現在只取出如下的信息，看是否是你需要的？如果是，我可以發布測試版本到服務器上。

yao:文，这些信息应该足够。

以下是一些关键代码：

 取一个组下的所有成员

public DataSet GetUsersForGroup(string GroupName)
