Hashtable Constructor (IDictionary, Single, IHashCodeProvider, IComparer)
Initializes a new instance of the Hashtable class by copying the elements from the specified dictionary to the new Hashtable object. The new Hashtable object has an initial capacity equal to the number of elements copied, and uses the specified load factor, hash code provider, and comparer.

A number in the range from 0.1 through 1.0 that is multiplied by the default value which provides the best performance. The result is the maximum ratio of elements to buckets.
null to use the default hash code provider, which is each key's implementation of Object.GetHashCode.
The initial capacity is set to the number of elements in the source dictionary. Capacity is automatically increased as required based on the load factor.
The load factor is the maximum ratio of elements to buckets. A smaller load factor means faster lookup at the cost of increased memory consumption. A load factor of 1.0 is the best balance between speed and size.
When the actual load factor reaches the specified load factor, the number of buckets is automatically increased to the smallest prime number that is larger than twice the current number of buckets.
The custom hash code provider and the custom comparer enable scenarios such as doing lookups with case-insensitive strings.
This constructor is an O(n) operation, where n is the number of elements in the d parameter.
