C # Use DirectoryEntry to manage window accounts

Recently, wss has been used for oa. The headache is that wss has not modified its own password, added users, and so on. Therefore, it is easy to implement
1. Account query;
2. group query;
3. Change the password (change the current logon password );
4. Create an account (not completed );
Note: It is not AD, but window account management. The specific code is very simple and will not be described much, mainly Member. cs class;

Open directly with vs2008 sp1. There are two portal pages:
1. In the Members/Find. aspx search window, you can search for accounts and search groups, view account and group information, query accounts by group, and query groups by account.
2. UserChangePassword. aspx is used to change the password of the current Logon account;
3. UserAdd. aspx adds an account because it is not very urgent and has not been implemented yet;

Implemented in c #, the key is to operate DirectoryEntry
