I'm trying to filter out entities from a
principalcollection using what I think is called lambda expressions.
I cant get this to work, I get no results.
user.GetGroups() returns all the groups where user is member, but
user.GetGroups().Where(....) does not return anything.
Lets say that userprincipal user = Administrator
Lets say MyFilterString = "Exchange"
Lets say that Administrator is member of the following groups:
Exchange Domain Servers Exchange Services Administrators Enterprise Admins
UserPrincipal user = new UserPrincipal(MyActiveDirectoryContext); .. .. PrincipalSearchResult<Principal> memberOfGroups = user.GetGroups().Where(g => g.SamAccountName.Contains(MyFilterString) == true) as PrincipalSearchResult<Principal>;
What I expect is that memberOfGroups should now contain 2 groups:
Exchange Domain Servers Exchange Services
But it ends up empty, zip zero, nada.
A little help is very much appreciated.

.Whereis the standard
Enumerable.Where, then it isn't going to ever return a
nullevery time. Consider using
