Qbservable.Multicast<TSource, TIntermediate, TResult> Method

Returns a queryable 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.Providers (in System.Reactive.Providers.dll)

public static IQbservable<TResult> Multicast<TSource, TIntermediate, TResult>(
	this IQbservable<TSource> source,
	Expression<Func<ISubject<TSource, TIntermediate>>> subjectSelector,
	Expression<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.Reactive.Linq.IQbservable<TSource>
The source sequence which will be multicast in the specified selector function.
subjectSelector
Type: System.Linq.Expressions.Expression<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.Linq.Expressions.Expression<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.Reactive.Linq.IQbservable<TResult>
A queryable observable sequence that contains the elements of a sequence produced by multicasting the source sequence within a selector function.
