The Observable type exposes the following members.

Methods

	Name	Description
	Aggregate	Applies an accumulator function over an observable sequence. The specified seed value is used as the initial accumulator value.
	Aggregate1	Applies an accumulator function over an observable sequence.
	All	Determines whether all elements of an observable sequence satisfy a condition.
	Amb	Overloaded.
	And	Matches when both observable sequences have an available value.
	Any	Overloaded.
	AsObservable	Hides the identity of an observable sequence.
	Average	Computes the average of a sequence of numeric values.
	BufferWithCount	Overloaded.
	BufferWithTime	Overloaded.
	BufferWithTimeOrCount	Overloaded.
	Case	Overloaded.
	Catch	Overloaded.
	CombineLatest	Merges two observable sequences into one observable sequence by using the selector function whenever one of the observable sequences has a new value.
	Concat	Overloaded.
	Contains	Overloaded.
	Count	Returns an number representing the total number of elements in an observable sequence.
	Create	Creates an observable sequence from the subscribe implementation.
	CreateWithDisposable	Creates an observable sequence from the subscribe implementation.
	Defer	Returns an observable sequence that invokes the observableFactory function whenever a new observer subscribes.
	Delay	Overloaded.
	Dematerialize	Dematerializes the explicit notification values of an observable sequence as implicit notifications.
	DistinctUntilChanged	Overloaded.
	Do	Overloaded.
	DoWhile	Repeats source as long as condition holds.
	Empty	Overloaded.
	Final	Returns an observable that contains only the final OnNext value.
	Finally	Invokes finallyAction after source observable sequence terminates normally or by an exception.
	For	Concatenates the observable sequences obtained by running the resultSelector for each element in source.
	ForkJoin	Overloaded.
	FromArray	Overloaded.
	FromDOMEvent	Overloaded.
	FromHtmlEvent	Overloaded.
	FromIEEvent	Overloaded.
	Generate	Overloaded.
	GenerateWithTime	Overloaded.
	GetType	(Inherited from Object.)
	GroupBy	Overloaded.
	If	If condition is true, then thenSource else elseSource.
	Interval	Overloaded.
	IsEmpty	Determines whether an observable sequence is empty.
	Join	Overloaded.
	Let	Overloaded.
	Materialize	Materializes the implicit notifications of an observable sequence as explicit notification values.
	Max	Returns the maximum value in an observable sequence.
	MaxBy	Overloaded.
	Merge	Overloaded.
	MergeObservable	Merges an observable sequence of observable sequences into an observable sequence.
	Min	Returns the minimum value in an observable sequence.
	MinBy	Overloaded.
	Never	Returns a non-terminating observable sequence.
	OnErrorResumeNext	Overloaded.
	Prune	Overloaded.
	Publish	Overloaded.
	Range	Overloaded.
	RemoveInterval	Removes the timestamp from each value of an observable sequence.
	RemoveTimestamp	Removes the timestamp from each value of an observable sequence.
	Repeat	Overloaded.
	Replay	Overloaded.
	Retry	Overloaded.
	Return	Overloaded.
	Sample	Overloaded.
	Scan	Applies an accumulator function over an observable sequence and returns each intermediate result. The specified seed value is used as the initial accumulator value.
	Scan0	Applies an accumulator function over an observable sequence and returns each intermediate result. The specified seed value is prepended to the sequence once a message comes in.
	Scan1	Applies an accumulator function over an observable sequence and returns each intermediate result.
	Select	Overloaded.
	SelectMany	Projects each value of an observable sequence to an observable sequence and flattens the resulting observable sequences into one observable sequence.
	Skip	Bypasses a specified number of values in an observable sequence and then returns the remaining values.
	SkipLast	Bypasses a specified number of values at the end of an observable sequence.
	SkipUntil	Returns the values from the source observable sequence only after the other observable sequence produces a value.
	SkipWhile	Bypasses values in an observable sequence as long as a specified condition is true and then returns the remaining values.
	Start	Overloaded.
	StartWith	Overloaded.
	Subscribe	Overloaded.
	Sum	Computes the sum of a sequence of numeric values.
	Switch	Transforms an observable sequence of observable sequences into an observable sequence producing values only from the most recent observable sequence.
	Take	Overloaded.
	TakeLast	Returns a specified number of contiguous values from the end of an observable sequence.
	TakeUntil	Returns the values from the source observable sequence until the other observable sequence produces a value.
	TakeWhile	Returns values from an observable sequence as long as a specified condition is true, and then skips the remaining values.
	Then	Matches when the observable sequence has an available value and projects the value.
	Throttle	Overloaded.
	Throw	Overloaded.
	TimeInterval	Overloaded.
	Timeout	Overloaded.
	Timer	Overloaded.
	Timestamp	Overloaded.
	ToAsync	Overloaded.
	ToLocaleString	(Inherited from Object.)
	ToString	(Inherited from Object.)
	Using	Retrieves resource from resourceSelector for use in resourceUsage and disposes the resource once the resulting observable sequence terminates.
	Where	Overloaded.
	While	Repeats source as long as condition holds.
	XmlHttpRequest	Overloaded.
	Zip	Merges two observable sequences into one observable sequence by using the selector function.
