Active Directory and asp .net

[iscuf]

Hello,

I'm building a web app where I like to query my users from active directory.
The code I'm working on it works fine for a user where all the properties that I'm query are filled in.

I'm trying already for a week to check if a property is empty but I'm stuck.

I need a method how I can check if a property is empty so I can use a string like "property empty". after testing I bring the AD up-to-date.

I hope there are some specialist over here so I can find a solution for my problem.

Many thanks in advance.

Check the proprty is empty or not using Properties.Cont ains("property" )

eg: if(adObject .Properties.Con tains("title"))

IsNullOrEmpty() function will not check the property is null
