I'm trying to get all the email addresses associated to a given AD user.
For the user I have the domain and the login name (ex. DOMAIN\\UserName) and I the AD is storing the email addresses in:
proxyAddresses
attributes. So far, I don't know what C# API to use to connect to the AD, and how to properly filter by the user to fetch all the email addresses. I'm using .NET 3.5.
Thank you.
Here's a possible solution using various classes in the System.DirectoryServices
namespace.
string username = "username";
string domain = "domain";
List<string> emailAddresses = new List<string>();
PrincipalContext domainContext = new PrincipalContext(ContextType.Domain, domain);
UserPrincipal user = UserPrincipal.FindByIdentity(domainContext, username);
// Add the "mail" entry
emailAddresses.Add(user.EmailAddress);
// Add the "proxyaddresses" entries.
PropertyCollection properties = ((DirectoryEntry)user.GetUnderlyingObject()).Properties;
foreach (object property in properties["proxyaddresses"])
{
emailAddresses.Add(property.ToString());
}
Have you looked at the DirectoryEntry class. You can pull properties from there given you have the LDAP string set up. The propery for mail is "mail" ironic aint it ?
