Stack<T>::TrimExcess Method ()
Sets the capacity to the actual number of elements in the Stack<T>, 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 Stack<T> 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 Stack<T> to its initial state, call the Clear method before calling TrimExcess method. Trimming an empty Stack<T> sets the capacity of the Stack<T> to the default capacity.
