.NET Standard API-referens version 1.5
Name | Description |
---|---|
System Namespace | Contains fundamental classes and base classes that define commonly-used value and reference data types, events and event handlers, interfaces, attributes, and processing exceptions. |
System. | Contains interfaces and classes that define various collections of objects, such as lists, queues, bit arrays, hash tables and dictionaries. |
System. | Contains interfaces and classes that define generic collections, which allow users to create strongly typed collections that provide better type safety and performance than non-generic strongly typed collections. |
System. | Contains classes that can be used as collections in the object model of a reusable library. Use these classes when properties or methods return collections. |
System. | Provides classes that are used to implement the run-time and design-time behavior of components and controls. This namespace includes the base classes and interfaces for implementing attributes and type converters, binding to data sources, and licensing components. |
System. | Provides classes that allow you to interact with system processes, event logs, and performance counters. |
System. | Provides types and members that enable you to create strongly typed events to be captured by event tracing for Windows (ETW). |
System. | Contains classes that define culture-related information, including language, country/region, calendars in use, format patterns for dates, currency, and numbers, and sort order for strings. These classes are useful for writing globalized (internationalized) applications. Classes such as StringInfo and TextInfo provide advanced globalization functionalities, including surrogate support and text element processing. |
System. | Contains types that allow reading and writing to files and data streams, and types that provide basic file and directory support. |
System. | Provides a simple programming interface for many of the protocols used on networks today. Classes in the System.Net namespace can be used to develop Windows Store apps or desktop apps. When used in a Windows Store app, classes in the System.Net namespace are affected by network isolation feature, part of the application security model used by the Windows Developer Preview. The appropriate network capabilities must be enabled in the app manifest for a Windows Store app for the system to allow network access by a Windows Store app. For more information, see the Network Isolation for Windows Store Apps. |
System. | Contains types that retrieve information about assemblies, modules, members, parameters, and other entities in managed code by examining their metadata. These types also can be used to manipulate instances of loaded types, for example to hook up events or to invoke methods. To dynamically create types, use the System.Reflection.Emit namespace. |
System. | Contains advanced types that support diverse namespaces such as the System, Runtime, and the Security namespaces. |
System. | Provides functionality for compiler writers who use managed code to specify attributes in metadata that affect the run-time behavior of the common language runtime. |
System. | Provides classes for advanced exception handling. |
System. | Provides a wide variety of members that support COM interop and platform invoke services. If you are unfamiliar with these services, see Interoperating with Unmanaged Code. |
System. | Contains managed types that correspond to types used by COM interop. |
System. | Contains advanced types that support versioning in side by side implementations of .NET. |
System. | Provides the underlying structure of the common language runtime security system, including base classes for permissions. |
System. | Contains classes that represent ASCII and Unicode character encodings; abstract base classes for converting blocks of characters to and from blocks of bytes; and a helper class that manipulates and formats String objects without creating intermediate instances of String. |
System. | Provides classes and interfaces that enable multithreaded programming. In addition to classes for synchronizing thread activities and access to data (Mutex, Monitor, Interlocked, AutoResetEvent, and so on), this namespace includes a ThreadPool class that allows you to use a pool of system-supplied threads, and a Timer class that executes callback methods on thread pool threads. |
