Hashtable Constructor (IHashCodeProvider, IComparer)
Initializes a new, empty instance of the Hashtable class using the default initial capacity and load factor, and the specified hash code provider and comparer.
Assembly: mscorlib (in mscorlib.dll)
[<ObsoleteAttribute("Please use Hashtable(IEqualityComparer) instead.")>] new : hcp:IHashCodeProvider * comparer:IComparer -> Hashtable
null to use the default hash code provider, which is each key's implementation of Object.GetHashCode.
A hash table's capacity is used to calculate the optimal number of hash table buckets based on the load factor. Capacity is automatically increased as required.
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.
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(1) operation.
