List of data types of the Standard Libraries
This is a list of data types of the Standard Libraries as defined in the ECMA-335 standard. Implementations of the Common Language Infrastructure must define the types of the standard in their respective standard libraries. The standard encourages implementers to extend or to modify the types specified in the standard to provide additional functionality.

Extended Array Library
The Extended Array Library provides support for non-vector arrays. That is, arrays that have more than one dimension or arrays that have non-zero lower bounds.[1] The Extended Array Library doesn't add any extra types, but it does extend the array-handling mechanism.[2]
