C# - 如何从 Active Directory 获取用户的“网页”属性？

Question

using System.DirectoryServices.AccountManagement;

string WebPage = "";
using (var context = new PrincipalContext(ContextType.Domain))
{
    var usr = UserPrincipal.FindByIdentity(context, System.Environment.UserName);
    if (usr != null)
        WebPage = usr.???????????;
}

I am able to get things like GivenName or EmailAddress, but the Web Page property is not an option. I am just using the Web Page property to store the users Slack channel ID for direct messages and would prefer not to repurpose the VoiceTelephoneNumber property, which I can acquire and have tested as working. Thanks in advance!

For any attribute that is not exposed by the UserPrincipal class, you can use GetUnderlyingObject() , which returns the underlying DirectoryEntry object, then get the attribute from the Properties collection. Like this:

WebPage = ((DirectoryEntry) usr.GetUnderlyingObject()).Properties["wWWHomePage"].Value;

This is one reason I don't bother with UserPrincipal at all. I have to resort to DirectoryEntry sometimes anyway. But also because of performance, which I wrote an article about: Active Directory: Better performance
