Assembly

Extension methods implementing the concatMapTo operator.

public static class ConcatMapToOperator

Inheritance

System.Object

ConcatMapToOperator

Methods

ConcatMapTo<TSource, TResult>(Observable<TSource>, Observable<TResult>)

Projects every value from source to the same innerObservable, regardless of the source value, concatenating each resulting subscription in order. Equivalent to source.ConcatMap(_ => innerObservable).

public static Observable<TResult> ConcatMapTo<TSource, TResult>(this Observable<TSource> source, Observable<TResult> innerObservable)

Parameters

source Observable<TSource>

The source sequence.

innerObservable Observable<TResult>

The observable to subscribe to for every value emitted by source.

Returns

Observable<TResult>

An observable that concatenates the values of every subscription to innerObservable, in source order.

Type Parameters

TSource

The type of values emitted by source.

TResult

The type of values emitted by innerObservable.

Remarks

Marked @deprecated upstream (in favor of concatMap(() => result)) but still present in rxjs 7.8.2, so it is ported here too. Like ConcatMapOperator, this does not port rxjs's deprecated resultSelector parameter — apply .Map(...) to the result for a projection.
