SortedList<TKey, TValue>.TrimExcess Method
Sets the capacity to the actual number of elements in the SortedList<TKey, TValue>, if that number is less than 90 percent of current capacity.
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<TKey, TValue> can be considerable, however, so the 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<TKey, TValue> to its initial state, call the Clear method before calling method. Trimming an empty SortedList<TKey, TValue> sets the capacity of the SortedList<TKey, TValue> to the default capacity.
The capacity can also be set using the Capacity property.
