Effective pagination with Active Directory searches

Question

What would be an effective way to do pagination with Active Directory searches in .NET? There are many ways to search in AD but so far I couldn\'t find how to do it effectively.

Answer 1

If SizeLimit is set to zero and PageSize is set to 500, the search will return all 12,000 results in pages of 500 items, with the last page containing only 200 items. The paging occurs transparently to the application and the application does not have to perform any special processing other than setting the PageSize property to the proper value.

SizeLimit limits the amount of results that you can retrieve at once - so your PageSize needs to be less than or equal to 1000 (Active Directory limits the maximum number of search results to 1000. In this case, setting the SizeLimit property to a value greater than 1000 has no effect.). The paging is done automagically behind the scenes when you call FindAll() etc.
