Remarks
The capacity of a Dictionary<TKey,TValue> is the number of elements that the Dictionary<TKey,TValue> can store. The Count property is the number of elements that are actually in the Dictionary<TKey,TValue>.
The capacity is always greater than or equal to Count. If Count exceeds the capacity while adding elements, the capacity is increased by automatically reallocating the internal array before copying the old elements and adding the new elements.
Getting the value of this property is an O(1) operation.
