AD sync from SQL server

Question

Hello.  I'm currently working on an app that will submit a query to a sql database containing user names and school names.  I will then take this information and use it to build one of our AD sub domains.  Once it has added the users, I will plan to have the app run every few days to verify everything is still synched, and change user attributes in AD if needed.
I have the first part working - I'm successfully able to query the sql db and pull in everything I want into a data table.  I'd like to do something similar with AD if possible, which would be to pull users' user names, first and last names, department (for storing unique identifier from sql db), and the OU they're in into a data table.   I feel that once I get them both in a data table, I'll be able to search through them for a unique identifier and verify that  everything matches.  I found a couple resources, but I haven't been able to make this work.  Below is some code I found that pulls in whatever the objectcategory is set to, but I haven't been able to figure out how to make it pull all the values i want into a data table.  A multidimensional array would probably work fine as well I would think. 
Any help would be appreciated.
Try
Dim enTry As System.DirectoryServices.DirectoryEntry = New System.DirectoryServices.DirectoryEntry("LDAP://DC=student,DC=domain,DC=local")
Dim mySearcher As System.DirectoryServices.DirectorySearcher = New System.DirectoryServices.DirectorySearcher(enTry)
mySearcher.Filter = ("(objectCategory=computer)")
Dim resEnt As System.DirectoryServices.SearchResult
For Each resEnt In mySearcher.FindAll()
Try
Console.WriteLine(":Processing:" & Mid(resEnt.GetDirectoryEntry().Name.ToString(), 4))
Catch ex As Exception
Console.WriteLine("Trying to Connect to: " & _
resEnt.GetDirectoryEntry().Name.ToString() & vbCrLf & ex.Message.ToString())
End Try
Next
Catch
