Observable.Multicast(Of TSource, TIntermediate, TResult) Method (IObservable(Of TSource), Func(Of ISubject(Of TSource, TIntermediate)), Func(Of IObservable(Of TIntermediate), IObservable(Of TResult)))

Returns an observable sequence that contains the elements of a sequence produced by multicasting the source sequence within a selector function.

Namespace:  System.Reactive.Linq
Assembly:  System.Reactive (in System.Reactive.dll)

'Usage
Dim source As IObservable(Of TSource)
Dim subjectSelector As Func(Of ISubject(Of TSource, TIntermediate))

Type Parameters

TSource

The type of source.

TIntermediate

The type of intermediate.

TResult

The type of result.

Parameters

source
Type: System.IObservable(Of TSource)
The source sequence which will be multicast in the specified selector function.
subjectSelector
Type: System.Func(Of ISubject(Of TSource, TIntermediate))
The factory function to create an intermediate subject through which the source sequence’s elements will be multicast to the selector function.
selector
Type: System.Func(Of IObservable(Of TIntermediate), IObservable(Of TResult))
The selector function which can use the multicasted source sequence subject to the policies enforced by the created subject.

Return Value

Type: System.IObservable(Of TResult)
An observable sequence that contains the elements of a sequence produced by multicasting the source sequence within a selector function.
