System.Reactive namespace¶

Part of the System.Reactive package.

Type	Kind	Summary
AnonymousObservable	class	Class to create an IObservable instance from a delegate-based implementation of the Subscribe method.
AnonymousObserver	class	Class to create an IObserver instance from delegate-based implementations of the On* methods.
EventPattern	class	Represents a .NET event invocation consisting of the strongly typed object that raised the event and the data that was generated by the event.
EventPattern	class	Represents a .NET event invocation consisting of the weakly typed object that raised the event and the data that was generated by the event.
EventPatternSourceBase	class	Base class for classes that expose an observable sequence as a well-known event pattern (sender, event arguments). Contains functionality to maintain a map of event handler delegates to observable sequence subscriptions. Subclasses should only add an event with custom add and remove methods calling into the base class's operations.
ExperimentalAttribute	class	Marks the program elements that are experimental. This class cannot be inherited.
IEventPattern	interface	Represents a .NET event invocation consisting of the strongly typed object that raised the event and the data that was generated by the event.
IEventPatternSource	interface	Represents a data stream signaling its elements by means of an event.
IEventSource	interface	Represents a data stream signaling its elements by means of an event.
IObserver	interface	Provides a mechanism for receiving push-based notifications and returning a response.
ITaskObservable	interface	Extension of the IObservable interface compatible with async method return types.
ITaskObservableAwaiter	interface	Interface representing an awaiter for an [ITaskObservable](#
ListObservable	class	Represents an object that retains the elements of the observable sequence and signals the end of the sequence.
Notification	class	Provides a set of static methods for constructing notifications.
Notification	class	Represents a notification to an observer.
NotificationKind	enum	Indicates the type of a notification.
ObservableBase	class	Abstract base class for implementations of the IObservable interface.
Observer	class	Provides a set of static methods for creating observers.
ObserverBase	class	Abstract base class for implementations of the IObserver interface.
TimeInterval	struct	Represents a value associated with time interval information. The time interval can represent the time it took to produce the value, the interval relative to a previous value, the value's delivery time relative to a base, etc.
Timestamped	class	A helper class with a factory method for creating [Timestamped](# instances.
Timestamped	struct	Represents value with a timestamp on it. The timestamp typically represents the time the value was received, using an IScheduler's clock to obtain the current time.
Unit	struct	Represents a type with a single value. This type is often used to denote the successful completion of a void-returning method (C#) or a Sub procedure (Visual Basic).
