Creates an object that can partition the underlying collection into a variable number of partitions.
An object that can create partitions over the underlying data source.
The returned object implements the IEnumerable`1 interface. Calling IEnumerable`1.GetEnumerator on the object creates another partition over the sequence.
Each partition is represented as an enumerator over key-value pairs. The value in the pair is the element itself, and the key is an integer which determines the relative ordering of this element against other elements.
The OrderablePartitioner`1.GetOrderableDynamicPartitions method is only supported if the Partitioner`1.SupportsDynamicPartitions property returns true.
