Question

I am trying to achieve an LDAP query to gather all properties we have about our users without specifying the properties before hand, I would like to display this in a table so u

Answer 1

This can be done using DirectoryEntry, but I don't think the SearchResultCollection has all fields.
Try to create a DirectoryEntry for every search result, it should have all active directory properties:

DirectoryEntry entry = result.GetDirectoryEntry();

Also, note that in the active directory every property can have multiple values (like the MemberOf field), so you'll have to iterate them as well.
I've wrote a similar method, but I chose a List with keys/values (it seemed more manageable over WCF. ILookup would be optimal, but I couldn't get it to work here). Here it is, stripped from try/catch/using

var list = new List>();
foreach (PropertyValueCollection property in entry.Properties)
   foreach (object o in property)
   {
       string value = o.ToString();
       list.Add(new KeyValuePair(property.PropertyName, value));
   }
