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)

[ExtensionAttribute]
public:
generic<typename TSource, typename TIntermediate, typename TResult>
static IObservable<TResult>^ Multicast(
	IObservable<TSource>^ source, 
	Func<ISubject<TSource, TIntermediate>^>^ subjectSelector, 
	Func<IObservable<TIntermediate>^, IObservable<TResult>^>^ selector
)

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

In Visual Basic and C#, you can call this method as an instance method on any object of type IObservable<TSource>. When you use instance method syntax to call this method, omit the first parameter.
