Type Parameters

Name Description
TSource The type of the elements in the source sequence.
TResult The type of the elements in the projected inner sequences and the elements in the merged result sequence.

Parameters

Name Type Description
source IObservable<TSource> An observable sequence of elements to project.
selector Func<TSource, IObservable<TResult>> A transform function to apply to each element.
maxConcurrent int Maximum number of inner observable sequences being subscribed to concurrently.

Return Value
