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.
System Defines types that provide an object representation of a uniform resource identifier (URI) and easy access to the parts of the URI. System.Collections.Specialized Defines specialized and strongly-typed collections; for example, a linked list dictionary, a bit vector, and collections that contain only strings. System.Net
add a new (,) pair to the collection, mapping the key to its new value. Any existing mapping is overwritten. The arguments to this operation are the key and the value. Remove or delete remove a (,) pair from the collection, unmapping a given key from its value. The argument to this operation is the key.
Data collection systems are an end-product of software development. Identifying and categorizing software or a software sub-system as having aspects of, or as actually being a "Data collection system" is very important. This categorization allows encyclopedic knowledge to be gathered and applied in the design and implementation of future systems.
A generic unit is a package or a subprogram that takes one or more generic formal parameters.

Based upon the generic syntax for Uniform Resource Identifiers (URI), CPE includes a formal name format, a method for checking names against a system, and a description format for binding text and tests to a name. [1] The CPE Product Dictionary provides an agreed upon list of official CPE names.
More generally, a collection of any sets whatsoever is called a family of sets, set family, or a set system. Additionally, a family of sets may be defined as a function from a set I {\displaystyle I} , known as the index set, to F {\displaystyle F} , in which case the sets of the family are indexed by members of I {\displaystyle I} .
