Assembly: System (in system.dll)
This method can be used to minimize a collection's memory overhead if no new elements will be added to the collection. The cost of reallocating and copying a large SortedList can be considerable, however, so the TrimExcess method does nothing if the list is at more than 90 percent of capacity. This avoids incurring a large reallocation cost for a relatively small gain.
This method is an O(n) operation, where n is Count.
To reset a SortedList to its initial state, call the Clear method before calling TrimExcess method. Trimming an empty SortedList sets the capacity of the SortedList to the default capacity.
The capacity can also be set using the Capacity property.
