Assembly: System.DirectoryServices (in System.DirectoryServices.dll)
The DirectorySearcher that created this collection calls the IDirectorySearch::ExecuteSearch method, which makes the query results available to the T:System.DirectoryServices.SearchResultCollection object. For more information, see the IDirectorySearch::ExecuteSearch topic in the MSDN Library at http://msdn.microsoft.com/library.
Each time that a query is performed, a handle for the results of that query is associated with its SearchResultCollection object. This handle corresponds to the search handle in ADSI. This handle persists until you call the Dispose() method on the SearchResultCollection object, so you must call Dispose() to prevent a memory leak. The garbage collector does not free memory for this particular object.
