CapacitySortedList 对象可存储的元素数。Capacity is the number of elements that the SortedList object can store. Count 是实际处于 SortedList中的元素的数目。Count is the number of elements that are actually in the SortedList.

Capacity 始终大于或等于 CountCapacity is always greater than or equal to Count. 如果在添加元素时 Count 超过 Capacity,则在复制旧元素并添加新元素之前,重新分配内部数组,将自动增加容量。If Count exceeds Capacity while adding elements, the capacity is automatically increased by reallocating the internal array before copying the old elements and adding the new elements.
