Observable.Multicast(TSource, TIntermediate, TResult) Method (IObservable(TSource), Func(ISubject(TSource, TIntermediate)), Func(IObservable(TIntermediate), IObservable(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)
static member Multicast : 
        source:IObservable<'TSource> * 
        subjectSelector:Func<ISubject<'TSource, 'TIntermediate>> * 
        selector:Func<IObservable<'TIntermediate>, IObservable<'TResult>> -> IObservable<'TResult> 

Type Parameters

TSource

The type of source.

TIntermediate

The type of intermediate.

TResult

The type of result.

Parameters

source
Type: System.IObservable(TSource)
The source sequence which will be multicast in the specified selector function.
subjectSelector
Type: System.Func(ISubject(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(IObservable(TIntermediate), IObservable(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(TResult)
An observable sequence that contains the elements of a sequence produced by multicasting the source sequence within a selector function.

Usage Note
