C#, LDAP, and Active Directory

[slvrscremr]

I have the following situation: Person A performs an application action that affects Person B. Management wants the application to automatically generate an e-mail to Person B, notifying them of the action. I can think of two solutions. 1) Query the Active Directory LDAP server for the e-mail address tied to Person B. 2) Get a dump of the e-mail addresses from the Exchange administrator and tie it into the application like another table. I don't like #2 because it doesn't account for change very well and I don't want to implement ANOTHER import/reconcile process if I don't have to. However, I've never done LDAP work and don't know how to exactly go about "eating this elephant". The proverbial answer is "one bite at a time", but where to start? :confused: BTW: The application is ASP. NET. The domain is Win Server 2000, Exchange 2000, and SQL Server 2000. Suggestions, pointers, hints, and help are welcome. Thanks in advance, Darien "I don't know. I haven't tried today." - Trumpet icon Maynard Ferguson's response when asked how high he could play.

Look at the System.DirectoryServices namespace. You can use a DirectorySearcher object and get the user account. The property to look for is "mail". I just did a phone/email list for a company last week. I don't have any of the code, but if you get stuck on something, I might be able to help. When getting the value of a property from a DirectoryEntry object, always do a .Contains("prpertyname") before trying to access the property. Not every entry will have the property you are after.
